The R4 series of infrared gas detection sensors utilise NDIR (Non Dispersive Infrared) to monitor the presence of Refrigerants, on which the sensor is precalibrated.
This technique is based on the fact that the gases have 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 analysing the optical absorption of the light that passes through the gas.
The sensor contains optics and incorporated electronics with software in order to provide an output that is linearised and temperature compensated. The output is digital MODBUS and analogue voltage type [0.4 V—2 Vdc].
The sensor provides a linearised and temperature compensated digital and analogue voltage output (voltage or dynamic pellistor) that is proportional to the gas concentration.
