Brief Introduction:
QB10N gas transmitter is used for toxic gas leak for continuous inspection for long time at site
It features high precision, passive output, LCD and reasonable price.
Generally, industrial sensors are installed on fixed type mild steel structures and a cable connects the detectors to a SCADA system for continuous monitoring.
A tripping interlock can be activated for an emergency situation.
The gas detector transmitter is equipped with LCD display for monitoring combustible gas density.It's widely used in the firefighting place,such like oil and gas transportation, biogas plant, methane treatment,etc.
Characteristics:
-Adopts the original imported sensors and advanced digital processing system
-High accuracy, stable, anti-toxic and anti-interference.
-Self-test technology in the sensor, automatical alert for short circuit, power supply fault, etc.
-4-20mA analog output for direct communication to DCS system
-Can be set with IR remote controller without open the upper enclosure.
-Highlight segment digital display real-time concentration
-Temperature compensation to ensure accuracy.
-Built-relay switch output
-Can be connected with audible-visual alarm.
-Over-range protection for gas sensor
