Product Overview
KQ500D series Fixed gas detector (also called gas sensor or gas transmitter). It can detect various gases such as flammable gas, O2,H2S,CO,HCN,NO2,SO2,NH3,HCL,CL2,H2 etc. Detect the gas density and transform it into 4~20mA electric current signal. With two-core or three-core shield cable, it gives high fidelity when transmit the signal to the controller through a long distance.
The detector has high sensitivity, quick response, long lifetime, polarization time and many other characteristics; it is among the first class in similar products in China.
Applications
It can be widely used in metallurgy, petrol, petrifaction, chemistry, light industry, coking, municipal administration, gas, pharmacy, sewage dealing and many other special industries and fields.
Main Features:
- Various kinds of gases detectors, high precision
- Fixed explosion-proof shell, safe and reliable
- Detect gas density in long distance, and transmit it to total controller in 4~20 mA electric current output
- Two-core or three-core shield cable, high fidelity
- Compatible with existing alarm unit or DCS ( distributed control system)
- Imported sensor, sensitive, high precision, quick response, stable performance
- Sipmple operation steps, easy to install and maintance
