Gas Sensors

The methane sensor detects gas concentration by natural diffusion and adopts imported catalytic combustion sensor with good sensitivity and excellent repeatability; the instrument adopts embedded micro-control technology, simple operation, complete functions, high reliability and reliable performance of the whole machine.

        The methane sensor is composed of cast aluminum housing, stainless steel sensor breathing device, sensor module, display module, main control module, digital communication module, dust cover and calibration cover.

        ◆ Standard 3-wire 4-20mA current signal output, compatible with existing alarm control units or DCS

        ◆ LED field display suitable for plant applications (optional LCD display)

        ◆ Automatic sensor fault identification and field display, while outputting the corresponding fault current signal

        ◆ -30～+60℃ temperature digital automatic tracking compensation to ensure measurement accuracy

        ◆ Standard three keys to achieve single person single point site maintenance

        ◆ On-site two-level light alarm, relay output (external sound and light alarm or drive the peripheral equipment such as exhaust air)
