Description
The XCL-LB-H2S-RA is a VESDA Sensepoint XCL Large Bore hydrogen sulphide (H2S) gas detector with a 50PPM measuring range. Its 4-20mA analogue output and relay wire straight into toxic-gas monitoring and alarm systems on Large Bore aspirated sampling networks.
XCL-LB-H2S-RA handles hydrogen sulphide sensing in the Xtralis Gas Detection XCL line, a VESDA Sensepoint XCL Large Bore gas detector spanning a 50PPM measuring range. Signalling combines a 4-20mA analogue output with a relay, so the detector can feed toxic-gas monitoring and alarm systems on Large Bore aspirated sampling networks over a current loop while also switching local circuits.
Read the full technical description
Configuration and any later reconfiguration of the unit are carried out through the Sensepoint App. When the sensing element needs renewal, the XCL-SC-H2S replacement sensor cartridge restores the 50PPM hydrogen sulphide cell without exchanging the detector itself. Physical connection and wiring detail follows the VESDA Sensepoint XCL - Large Bore Installation Manual, and an Xtralis warranty covers the detector against defects in parts and workmanship.
