Overview
HRP-T1000-EX combustible 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, can be adjusted without opening the lid, 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 completes the digital display and alarm operation after analysis and processing. Support the input signal of various standard transmitters, such as gas transmitters: carbon monoxide, hydrogen sulfide.
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. Use infrared remote control to adjust the detector without opening the lid
2. Connect the cable and ensure that the cable is ≥ 1.5mm ² × 3 or ≥ 1.5mm ² × 4
3. Provide DC24V +/- 15% power supply
4. Acquire 4-20mA transmitter input signal 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
Notice
• Working ambient temperature range -20~ 70 ℃, humidity < 95%
• The maximum distance between the detector and the host does not exceed 1000m
• Operating Pressure must be kept at 86~ 106kPa
• Power consumption does not exceed 3W to ensure stable power supply
• Only suitable for hazardous conditions zones 1 and 2, following explosion-proof requirements
