Detector de gas de combustible de punto industrial y comercial GT-TCB3

Descripción

The outstanding feature of the GT-TCB3 industrial and commercial point-type combustible gas detector is that it uses high-performance imported catalytic combustion, electrochemical, and infrared dual-beam gas sensors, combined with sophisticated SMD technology. It has good repeatability and resistance to moisture and temperature interference, long service life, and easy operation. It is suitable for gas leakage concentration detection in various industrial environments.

The GT-TCB3 industrial and commercial point-type combustible gas detector can convert the leakage gas concentration signal in the air into an electrical signal output for remote transmission. It uses a three-wire 4-20mA, a four-wire RS485 bus (or a two-wire system), a passive switch signal structure, and the monitoring instrument or controller host can view the detection results away from the site.

The GT-TCB3 industrial and commercial point-type combustible gas detector is suitable for refineries, chemical plants, liquefied gas stations, gas boiler rooms, gas stations, paint rooms, pharmaceuticals, iron and steel smelting, and other industrial sites that use flammable and explosive materials and toxic and harmful materials for gas safety detection and alarm control.
