Overview
HRP-T1000-O2 oxygen gas detector 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 factory areas. The wiring method is suitable for various dangerous places.
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, and analyzes and processes it to complete the digital display and alarm operation. The system supports the input signal of each standard transmitter, such as gas transmitter: carbon monoxide, hydrogen sulfide.
Applications
Gas safety detection and alarm in places that require fire prevention, explosion prevention and poisoning prevention, such as petroleum exploration and production, oil and gas transportation, oil refining, metallurgy, power plants, chemical industry, oil depots, liquefied gas stations, mines, tunnels, tunnels, underground pipelines, etc
Standards
Explosion-proof marking: Ex d ⅱ C T6 Gb
Steps
1. Use infrared remote control or button operation for debugging
2. Connect DC24V +/- 15% power supply
3. Upload data to DCS and PLC system through 4~ 20mA standard Analog Output or RS485 digital output
4. Monitor LED digital tube display concentration value and LED light indication status
