Overview
Specifications

Description

The GDA 4350 Carbon Dioxide Gas Sensor is a 3 wire Non Dispersive Infra red (NDIR) Carbon Dioxide (CO₂) sensor. It gives a 4-20 mA, 0-20 mA, 0-5 V or 0-10 V o/p over the range of the sensor.

Housed in an ABS plastic case with an aperture for the gas path. It uses laser LED to give reliable performance. Calibration for non critical safety applications is every 3 years. The low temperature version (suffix LT) operate from - 25°C to 30°C.

Highlighted Features

24 VDC, 3 Wire Operation
4-20 mA, 0-20 mA, 0-5 V or 0-10 V o/p linear over range of sensor
Ultra low cross sensitivity to other gas
Temperature and humidity compensated
Multiple ranges
No moving parts.
Factory calibrated
Low drift

Designed, manufactured and supported locally in Australia.
