Fixed wall-mounted liquid ammonia leak detector

Fixed wall-mounted liquid ammonia leak detector:) The liquid ammonia leak alarm consists of a liquid ammonia controller and a liquid ammonia detector. The liquid ammonia controller is placed in the duty room to display the leakage liquid ammonia concentration value. When the concentration of the detected gas reaches the preset alarm value, the controller immediately issues an audible and visual alarm. At the same time, it can drive the exhaust, cut off the pipeline, and start spraying. system to prevent poisoning accidents.
Special technical requirements: The detector inputs power and outputs a current signal. The controller can output two sets of passive switching signals, one set is open (level one alarm), and a set of normally open pulse signal (level two alarm) Alarm), the first level alarm in multi-channel is, the second level alarm is,.
The product has passed: China National Compulsory Product Certification, Explosion-proof Certificate, People's Republic of China Manufacturing Measuring Instrument License, Type Approval and other certificates. And the alarm is insured.
Technical parameters of liquid ammonia controller:
.Alarm output: power connection detector, /3 control exhaust fan, solenoid valve, etc.
