Use of Toxic Gas Detection Alarms
In the industrial environment, when the combustible or toxic gas leakage, the gas alarm detects the gas concentration reaches the critical point set by the alarm, the alarm will send out an alarm signal to remind the operators to take safety measures and drive the exhaust, cut off, spraying system to prevent explosion, fire, poisoning accidents, so as to ensure the safety of production.
In the chemical production process, to use or produce a variety of hazardous chemicals, which have toxicity and explosive properties of more substances, the danger is also greater. In the process design, not only through the use of closed operation, maintain a safe distance, set up mechanical ventilation, to ensure that the pressure relief area and other means to ensure the safety of production, through the adoption of the necessary monitoring measures will also greatly reduce the risk.
Toxic gas detection and alarm instrument: QD6330 with display gas detection transmitter can be applied to flammable and explosive gas leakage and its toxic and hazardous presence of chemical plants, gas detection instrumentation using foreign catalytic combustion sensors and their U.S. imports of electrochemical sensor technology, the product has a stable signal, high precision, the instrument enclosure using cast aluminum one-time molding of explosion-proof and explosion-proof design, the wiring method is suitable for All kinds of dangerous places.
Gas detection alarm instrument product features:
1. Alarm record query function
2. Detection accuracy, adjustable range
3. Long service life, high sensitivity, low drift, stable and reliable work.
4. Sensor failure self-test, two-level concentration alarm, with relay output function
5. Liquid crystal or digital tube gas concentration digital display and work status display.
6. Temperature compensation, automatic zero correction function.
7.4-20mA or RS485 digital output, can be uploaded to DCS, PLC system.
8. Infrared remote control mode, without opening the cover can be adjusted to the detector, safe and convenient.
9. Adopting explosion-proof design suitable for hazardous conditions 1, 2 zones.
Toxic gas detection alarm instrument is widely used in pharmaceutical, chemical fertiliser, natural gas network, sewage treatment, municipal, iron and steelmaking, acetylene plant, refrigeration workshop, chemical workshop, gas station area, boiler room, hotel kitchens, such as the need for anti-toxic fire and explosion-proof places.
