Standard and Extended Temperature Optical Liquid Level Sensors - LLC200D324-003

Standard and Extended Temperature Optical Liquid Level Sensors - LLC200D324-003

Standard and Extended Temperature Industrial Series Optical Liquid Level Sensors
  • Standard and Extended Temperature Optical Liquid Level Sensors

Product Specification

GENERAL DESCRIPTION
The LLC Industrial Series liquid level sensor provides single point liquid detection via a TTL compatible output.
This  sensor  range  was  designed  to  directly  switch incandescent indicators, sounders, relays or applications which require higher output power.

An infra-red LED and phototransistor accurately positioned at the base of the sensing tip ensure good optical coupling between the two when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes from the cone causing a change in the amount of light detected at the phototransistor which makes the output change state. Various electrical outputs are available to suit different applications.

CLEANING
Proper fluids should be selected based on type of contamination to be removed. SST Sensing recommends freon and alcohol based solvents. DO NOT use chlorinated
solvents such as tricholorethane as these are likely to attack the sensor material.
LIQUID MEDIA COMPATIBILITY
Before use check that the fluid in which you wish to use these devices is compatible with either polysulphone or trogamid.

NTM SenseH2 Hydrogen Sensor

Product Specification

Overview

Designed for hydrogen monitoring, this ceramic sensor exhibits a highly sensitive, selective, and rapid response to the
presence of hydrogen in ambient air. It reliably measures H2 concentrations over a wide range of temperature and
humidity variation and provides a repeatable response, even in the presence of other combustible gases. Additionally,
the NTM SenseH2® hydrogen sensor is immune to signal saturation upon continuous exposure to low levels of hydrogen,
and recovers rapidly and completely upon hydrogen removal.

System Components

Sensor: The sensor element employs a patent‐pending, chemi‐resistive ceramic technology, which provides accurate
and reliable hydrogen detection.
