Fixed propylene gas detector with audible and visual alarm

Propylene gas detector Multigas testing &imported sensor stainless steel enclosure 4-20mA/RS485 output detection for all gas

GQB-200G10 Fixed propylene gas detector alarm with audible and visual alarm

Compound gas transmitter GQB-200G10 with stainless steel shell is a symbol of high quality transmitters.Its has the characteristics of high-precision display; intelligentized operation; ability of Digital network signal transceiver; multi-sensor design, testing two gas concentrations.low unit costs;Advanced PnP technology allows charged replacement for different kinds of sensors; Intelligent life counter can read sensor life at any time to determine whether need replacement or not.

Performance and characteristics

 

1 test two different gases simultaneously

2 in the same domestic industry have no this technology application

3 4-20mA, Rs485 main line system (optional)

4 120dB explosion-proof sound-light alarm

5 high brightness LED can be instructed in ten metres away

6 the original imported sensor

7 stainless steel shell

Rs485 and 4-20mA double output can access any field devices Calibrating wihtout open cover and makes operation more convenient.

 Certificates

1.one patent of practical new technique.

2.two patents of appearance technique.

3.fire control type approval of the ministry of public security.

4.National explosion-proof electric inspection.

Characteristic of sensor

1.plug and play any time

2. High concentrations protection (applies only to catalytic sensor)

3. High precision & wide range hardware VGA (variable gain amplifier) avoids the sensitivity decrease brought only by software amplification.

4. Each probe contains a extra temperature sensor to compensate the impacts to gas sensor by temperature.

5. Artificial intelligence compensation technology makes reading more smooth and stable.

6. Sensor lifetime system from the viewpoint of sensor helps the user know whether the sensor need to replace or not.

7. Double output of current completely satisfy the requirements of Dual-use machine.

 

The compound gas transmitter of GQB-200A10 is applied for semiconductor, catalytic combustion, electrochemistry, nondispersive infrared and PID sensors and can be used between any two kinds of the above sensors. It’s the first choice of exceeding the imported products and complex gas ambients.

Attention: GQB-200G10 cannot be applied for two catalytic combustion sensors working at the same time.
