Product Information

LS series OEM Refrigerant Gas Sensor Description
LS series gas sensors are designed for maximum sensitivity and speed they do not have a reference channel. Thus a calibration procedure (background detection) is needed with these sensors. Each sensor consists of an I.R. detection cell and an electronic board. The board is equipped with a micro-processor which performs the measurement and transmits it to any external control unit via an RS-232 protocol. For complete operations the sensor requires an RS-232 line, DC power supply (+/- 15 V) and connection to a suitable pneumatic circuitry to allow the gas being tested to flow into the cell.

Our sensors for trace gas detection adopt the N.D.I.R. (Non Dispersive Infra Red) Tecnology. This technology is based on light absorption at selected wavelengths for each different gas.

(1) the sensor response time can be set on customer demand. A faster response time means a lower detector precision.
(2) Sensor parameters are factory set for this flow rate. Different settings available on demand.
(3) Baud-rate=9600 (it can be differently set on customer demand), Data bits=8, Parity=none, Stop bits=1.
