Overview
HRP-T1000-NH3 ammonia gas detector is an explosion-proof Gas detection instrument of HUIRUIPU brand. It adopts catalytic combustion Sensor and Electrochemical sensor technology imported from the United States, which has the advantages of stable signal and high accuracy. The shell adopts cast aluminum one-time molding explosion-proof and explosion-proof design, which is suitable for various dangerous places. This product is widely used in chemical fertilizers, natural gas pipe networks, sewage treatment, municipal, iron and steel making, chlorine plants, acetylene plants, refrigeration workshops, chemical workshops, gas station areas, boiler rooms, hotel kitchen operation rooms and other places that need anti-poison, fire and explosion-proof.
Features
1. Adjustable detection accuracy and range
2. Long Life, High Sensitivity, Low drift, Stable and Reliable
3. Two-stage concentration alarm with relay output function
4. LCD display and working status display
5. With temperature compensation, automatic zero correction function
6.4~ 20mA standard Analog Output and RS485 digital output, can be uploaded to DCS, PLC system
7. Infrared remote control method, the detector can be adjusted without opening the lid, which is safe and convenient
8. Flameproof design suitable for hazardous conditions 1 and 2 zones
Principle
The system provides 24V standard DC voltage to the external transmitter, collects the input signal of the standard 4-20mA transmitter, and analyzes and processes it to complete the digital display and alarm operation. The system supports the input signals of various standard transmitters, such as gas transmitters: carbon monoxide, hydrogen sulfide, etc.
