Overview
HRP-T1000-O2 oxygen gas detector is an explosion-proof Gas detection equipment 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 is designed with cast aluminum one-time molding explosion-proof and explosion-proof design, which is suitable for flammable and explosive gas leakage and toxic and harmful 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. 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.
Applications
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
Standards
Explosion-proof marking: Ex d ⅱ C T6 Gb
Steps
1. Use the infrared remote control for debugging without opening the lid
2. Connect DC24V +/- 15% power supply
3. Upload to DCS and PLC system through 4~ 20mA output signal or RS485 digital output
4. Monitor the concentration value of LCD liquid crystal display and LED light indication status
