Overview
HRP-T1000-O2 oxygen gas detector adopts Electrochemical sensor technology, 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 instrument is widely used in chemical fertilizers, natural gas pipe networks, sewage treatment, municipal, iron and steel making, chlorine gas plants, acetylene plants, refrigeration workshops, chemical workshops, gas station areas, boiler rooms, hotel kitchen operation rooms and other places that need anti-toxic, fire-proof 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. 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
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. Provide 24V standard DC voltage
