Brief introduct of Gas detector:
Fixed ammonia detector can also have a field detection concentration display, signal transmission, led lights and relay alarm function.Volkswagen series shows the fixed ammonia detector works is the site of the detection of ammonia gas concentration, converted to the corresponding standard signals (such as voltage signals (such as 0-5 / 10V), current signals (such as 4-20mA) , Standard digital signals (such as bus RS-485, RS232), frequency signal, Hart protocol signal, and then send the signal to the PLC, DCS, alarm control host and other host computer for unified display, management and control. Gas detector with a relay inside (switch signal), you can control the fan, sound and light alarm, solenoid valve and other equipment.
Features of Gas detector:
1.Volkswagen series Wall-mounted ammonia detector can be connected to the Ampel server to achieve mobile phone and computer remote monitoring, alarm reminders and alarm settings, etc.
2.Ultra-high-definition color display. Long distance visual, visual distance of 10 meters (5.0 vision).
3.Standard signal output range; Volkswagen series with fixed ammonia detector display cable output signal has a variety of options
4.Chinese and English lanuage switch free.
5.Black box function: operation, alarm records, over-temperature use records, over-range use records;
6.Reminders and alarm function is complete: sensor expiration reminder function, ultra-concentration alarm function, over-temperature alarm function,
Fault alarm function, instrument calibration reminder function;
