Compact NDIR Gas Sensor Modules

Electro Optical Components offers a wide range of N.E.T. sensors based on the Non Dispersive InfraRed principle (NDIR), designed for a reliable detection of the following gases:


Different from other sensors on the market, IRNET-P sensors have a microprocessor for internal signal processing, offering an engineered output, already linearized and temperature compensated. For this, IR sensors are suited for instrument manufacturers without any specialist knowledge in IR technology.

Main features of NDIR sensors:

IR PART NUMBER SPECIFICATIONS

NDIR sensors for CO2 or HC detection

The IR series of infrared gas detection sensors uses the technique of NDIR (Non Dispersive Infrared) to monitor the presence of hydrocarbons or carbon dioxide. This technique is based on the fact that the gas has a unique and well defined light absorption curve in the infrared spectrum that can be used to identify the specific gas. The gas concentration can be determined by using a suitable infrared source and analyzing the quantity of energy absorbed from the gas inside the optical path.

Advanced NDIR Sensors for SF6 or Refrigerant Gas Detection

A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle. Most of the gases in refrigeration plants have adverse environmental effects and could be dangerous for humans. The IR series of infrared gas detection sensors use the technique of NDIR (Non Dispersive Infrared) to monitor the presence of SF6 and refrigerants. This technique is based on the fact that the gas has an unique and well defined light absorption curve in the infrared spectrum that can be used to identify the specific gas.

The gas concentration can be determined by using a suitable infrared source and analyzing the quantity of energy absorbed from the gas inside the optical path. The IREF-P sensors are equipped with electronics and firmware in order to provide an output that is linearized and temperature compensated. The output is analogue voltage type [0.4 V-2 V] dc (other voltages are available on request).
