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 flammable and explosive gas leakage places and toxic and harmful chemical plant areas and other dangerous environments.
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. With temperature compensation, automatic zero correction function
5.4~ 20mA standard Analog Output and RS485 digital output, can be uploaded to DCS, PLC system
6. Infrared remote control method, the detector can be adjusted without opening the lid, which is safe and convenient
7. Use flameproof design 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, analyzes and processes it to complete the digital display and alarm operation. The system supports the input signal of each standard transmitter.
Applications
Chemical fertilizer, natural gas pipeline network, sewage treatment, municipal, metallurgical steelmaking, chlorine plant, acetylene plant, refrigeration workshop, chemical workshop, gas station area, boiler room, hotel kitchen operation room, oil exploration and production, oil and gas transportation, refining, metallurgy, power plants, chemical industry, oil depot, liquefied gas station, mine, tunnel, tunnel, underground pipeline
Standards
Explosion-proof marking: Ex d ⅱ C T6 Gb
Steps
1. Debugging through infrared remote control or button operation
2. Connect DC24V +/- 15% power supply
3. Use ≥ 1.5mm2 cable connection, the distance between the detector and the host does not exceed 1000m
4. The system collects the input signal of the 4-20mA transmitter for analysis and processing
5. The concentration value is displayed through the 4-digit LED digital tube, and the LED light indicates the power supply and alarm status
