Product Details

1、 Product Overview

The TCB3 digital gas detector is characterized by the use of catalytic combustion, electrochemical, and infrared dual beam gas sensors, combined with sophisticated SMD technology manufacturing. It has good repeatability and resistance to humidity and temperature interference, long service life, and easy operation. Suitable for detecting gas leakage concentration in various industrial environments.

The TCB3 digital gas detector can convert the concentration signal of leaked gas in the air into an electrical signal for remote transmission. It adopts signal structures such as three wire 4-20mA, four wire RS485 bus, passive switch quantity, etc. The monitoring instrument or controller host is far away from the site to observe the detection results.

The TCB3 digital gas detector product is suitable for gas safety detection, alarm and control in industrial sites such as refineries, chemical plants, liquefied gas stations, gas boiler rooms, refueling stations, paint spraying rooms, pharmaceuticals, iron and steel smelting where flammable and explosive materials, toxic and harmful substances are used.
