BH-60 Zetron Natural Gas Leak Detector With 4~20mA Signal Measurement Inspecting
BH-60 Fixed Gas Detector
BH-60 fixed gas detector adopts advanced catalytic gas sensor or electrochemical sensor, which can translate the gas concentration in the air to the digital signal output. The detector working with gas controller can be used to detect gas in refinery, chemical plant, LPG station, boiler room, painting plant and other places with gas exists.
Detection principle:
The system provides 24V standard DC voltage to the external detector, collecting standard (4-20) mA input signal to analyze and complete the digital display and alarm operation.
BH-60 fixed gas detector can be connected with control panel, alarm information would be display in the control panel by uploading 485 or (4-20) mA. Gas technical parameter settings shows as in Appendix 1.(For reference only, users can set parameters according to specific conditions.)
