Gas transmitter KwikSense with display, output 4-20mA and relays

The gas transmitter ATEX KwikSense

The digital gas transmitter KwikSense is available exists in two versions:

KwikSense gas detector

The gas transmitter KwikSense is fitted with plug-n-play intelligent sensor technology allowing swapping of any sensor on the gas transmitter. It is thus possible to replace an electrochemical cell with a PID lamp or an infrared sensor.

This revolutionary technology of intelligent sensors, pre-calibrated at the factory, automatically sends the parameters (cell type, measurement range, alarm thresholds, etc.) into the gas transmitter. That facilitates the maintenance operations and the associated costs, as there is no need to perform a calibration after their replacement.

The KwikSense digital gas transmitter has 3 alarm relays for control, 4-20 mA and MODBUS outputs as standard, HART, and optional SIL2 certification.

The KwikSense Lite gas detector

This 'low cost' version offers the same pre-calibrated gas detection cells as the KwikSense but without the possibility of interchanging them. It also has a digital display but only one alarm relay for the controls and 4-20mA output for connection to a gas detection system.

Many accessories are available for both versions of the KwikSense digital gas transmitter depending on the needs and the applications, such as: a calibration cap, a gas manifold, a weather shield, a pipe
mounting kit, or a duct mounting kit.
