Why use an SO2 sensor?


Why use an SO2 sensor?

Sulfur Dioxide gas (SO2) is a toxic gas with a strong irritating smell. It is present at very low concentrations in the atmosphere and is naturally emitted during volcanic eruptions. Inhaling sulfur dioxide has been associated with respiratory disease and difficulty breathing. It is also a precursor to acid rain and atmospheric particulates. Sulfur dioxide gas can be an active component or a waste product of several different industrial processes.

Atmospheric Sulfur Dioxide

Fossil fuel combustion at power plants is the largest emission source of sulfur dioxide into the atmosphere. Other sources include extracting metal from ore and the burning of high sulfur containing fuels by ships, trains and machinery. Perimeter monitoring at industrial sites is common to measure the concentration of sulfur dioxide being emitted into the atmosphere. isweek offer both fixed and portable monitors with an SO2 sensor suitable for long term outdoor perimeter monitoring as well as shorter term human exposure studies.

Industrial Uses of Sulfur Dioxide

Sulfur dioxide is an intermediate component in the formation of sulfuric acid. Sulfuric acid is a very important commodity chemical used in several industrial processes including the removal of oxidation and rust from metal sheeting. Sulfur dioxide gas is also used directly in many industries. It acts as a preservative for dried fruits due to its antimicrobial properties and is used in wine making to protect the wine from spoilage. isweek can provide a range of instruments for industrial monitoring of sulfur dioxide.

Things to Consider When Buying Carbon Monoxide Sensors


Things to Consider When Buying Carbon Monoxide Sensors

Before you buy, it’s good to break down exactly what to look for in a carbon monoxide Sensor. We’ll highlight several key factors that were part of our decision-making process to help you become a more informed consumer, but if you’d like to skip to the details on our recommended models, you can do that here.
Carbon Monoxide Sensor (CO Sensor) 4-Electrode

What Are the Symptoms of Carbon Monoxide Poisoning?

Carbon Monoxide doesn’t have a smell or taste, so you might not know right away that you’re being poisoned, but your body will. If you have carbon monoxide poisoning, you may feel dizzy, become nauseous, throw up, develop a headache, get confused, or pass out. It’s often been said that the signs of CO poisoning might resemble the flu.
Every year, 400 Americans die from accidental carbon monoxide poisoning (from fuel burning, not fires), and 20,000 are admitted to the emergency room.1 If you become unconscious while carbon monoxide is filling your home, it can be life threatening. That's where carbon monoxide Sensors come into play. Once installed, they can alert you about high levels of carbon monoxide in your home, which will give you more time to get to safety.

Who Is Most Susceptible to CO Poisoning?

Everyone is susceptible to carbon monoxide poisoning. But, according to the Centers for Disease Control and Prevention (CDC), children, older adults, people who are physically ill, and pets are more likely to be affected by CO.2 The Mayo Clinic adds that unborn babies’ blood cells take in more CO than adult blood cells, which makes them more susceptible to poisoning.3 Older adults who experience high levels of CO could be more likely to incur brain damage.
When it comes down to it, a CO Sensor can help save your life and the lives of the people you love.

What to Do If You Suspect High Levels of Carbon Monoxide

If you or your family members experience carbon monoxide poisoning symptoms, quickly walk outside for fresh air and call 911. Even if you start to feel better, you can still have toxic levels of CO in your system and might require medical help. In this situation, it’s a good idea to have your whole family checked for poisoning, including your pets. Signs of carbon monoxide poisoning don’t always happen right away—it can happen over the period of days and possibly even weeks, depending on the levels of CO in your home.

What Is a Carbon Monoxide Sensor?

Carbon monoxide Sensors are a lot like smoke Sensors, but instead of looking for signs of fire, they detect levels of carbon monoxide. Depending on the brand, Sensors operate in one of three ways: with a biomimetic sensor, metal oxide semiconductor, or electrochemical sensor.
Biomimetic Sensors use gels that change color after absorbing a certain amount of carbon monoxide—and then a sensor sounds an alarm. Metal oxide semiconductors have silica chips that detect CO and send electrical signals to trigger an alarm. Electrochemical sensors are considered to be the best in the industry. They use electrodes in chemical solutions that sense changes in electrical currents when carbon monoxide is present, and they sound an alarm.
If you have a professionally monitored security system installed, it should come with a CO Sensor.

Where to Install Carbon Monoxide Sensors

The Consumer Product Safety Commission recommends putting a carbon monoxide Sensor outside every separate sleeping area in your home.4 You might also want to add a carbon monoxide Sensor in your kitchen and basement for added safety. Also, make sure you install Sensors close to bedrooms so alarms will wake you up if you're sleeping.
If you have an attached garage, you’ll want to place a CO Sensor by the entranceway. A vehicle that’s been left running in a closed space is a common cause for CO poisoning. In the grand scheme of things, it’s better to be overly cautious by placing CO Sensors in every room, floor, and hallway than suffering CO poisoning.

How to Maintain a Carbon Monoxide Sensor

Most carbon monoxide Sensors last an average of five years. Although the product’s lifetime will vary depending on your make and model, you can still get the most out of your Sensor by wiping it down weekly to keep it clean from dust and debris.
It’s also a good idea to test your CO Sensor monthly. Start by pressing the “test” button to ensure the siren works. If your Sensor is older, you can purchase a carbon monoxide test kit to ensure that it’s fully functional. If the Sensor doesn’t go off when you test it, it’s probably time to buy a new one.

How Liquid Level Sensors Work

Level sensors are used to monitor and regulate levels of a particular free-flowing substance within a contained space. These substances are usually liquid, however level sensors can also be used to monitor some solids such as powdered substances. Level sensors are widely used industrially. Cars use liquid level sensors to monitor a variety of liquids, including fuel, oil and occasionally also specialist fluids such as power steering fluid. They can also be found in industrial storage tanks, for slurries, and in household appliances such as coffee machines. Basic level sensors can be used to identify the point at which a liquid falls below a minimum or rises above a maximum level. Many sensors can detail the specific amount of liquid in a container relative to the minimum/maximum levels, to provide a continuous measurement of volume.
There are a number of different types of liquid level sensor used to detect the point level of a liquid. Some types use a magnetic float, which rise and fall with the liquid in the container. Once the liquid, and by extension, the magnet, reach a certain level, a reed magnetic switch is activated. Commonly, there is a switch towards the top and the bottom of the container, allowing detection of minimum and maximum levels of liquid. Many sensors also include a protective shield to protect the magnet from turbulence or interference from direct contact with the liquid.
Another common type of level sensor is known as a Conductive sensor. Only liquids which conduct electricity can be used in this sensor. This type of sensor includes a source of power, usually of a fairly low voltage. At least two electrodes are placed within the container. When a conductive liquid reaches a certain point, it will come into contact with both a longer and a shorter electrode, and thus complete a circuit and activate an internal switch.
Pneumatic sensors are also a fairly common occurrence with particularly hazardous liquids, or in systems where the use of electricity is not viable or possible. This is because the sensor itself does not come into direct contact with the liquid at all. The sensor detects the level of air between the liquid and the pneumatic sensor, then uses this to calculate the amount of liquid used to fill the remainder of the container. These types of sensors are also relatively cost-effective.
There are also other types of level sensors which offer continuous measurement of liquids. Magnetostrictive sensors are similar in design to regular magnetic float sensors, yet the magnet level is measured using a magnetostrictive wire, which will react when its magnetic field is interrupted by the presence of the magnet. The exact point at which this interruption occurs can be determined by the distance between the bottom of the wire and the point of interference. Alternatives to this design include a magnetoresistive sensor, whereby an additional magnet is inserted onto the arm of the float, allowing accurate triangulation of the exact position of the magnets. This type of sensor is commonly used in conjunction with computer programs due to its accuracy.

Rain Collector Sensor - Rainfall Sensor


Rain Collector Sensor - Rainfall Sensor

Rain Collector Sensor
Rain Collector Sensor Rainfall Sensor
This self-emptying, tipping bucket style rain collector utilizes an 8" diameter openning to meet NWS specifications for statistical accuracy. Rainfall is gathered in the collecting bucket and funnels through a small openning into a tipping mechanism. When the mechanism has 1/100th of an inch of water in it, it tips.  A count is then transmitted to an indicator and the water emptys from the tipping mechanism, through the bottom of the collector bucket to the outside.

Rain Collector Sensor Rainfall Sensor
Tipping bucket, self-emptying rain collector.  8" diameter openning meets NWS specifications for size and accuracy.
Dimensions: 8.63" O.D. x 7.88" Deep
Weight: 1.77 lbs.

The rainfall collector requires no manual emptying. Each tip of the bucket is equivalent to 1/100th of an inch of rain. It utilizes a normally open circuit that is momentarily closed each time it tips.  As such, it can be connected to any simple counting circuit, including Maximum's Rainwatch indicator.

Rain Collector Sensor Rainfall Sensor Features
Outside rainfall collector meets NWS specifications for size and accuracy, and is self-emptying for your convenience.
The collector bucket can remain outdoors year-round.  Freezing weather will not damage the collector, but readings of snow or freezing rain are not to be considered accurate readings of rainfall.
Ships complete with 60', 22 AWG, 2-wire, UV protected cable.
