Leak Detector for Ammonia Refrigeration
Model LBW-420-LEL is designed for catastrophic leak detection and response before you get to the lower explosion level (LEL). It displays ammonia concentration in percent from 0 to 9.9. It has a 4 to 20 mA analog output, scalable for 0 to 1 percent, 0 to 2 percent, or 0 to 10 percent. It has three latching relays capable of shutting down equipment. The detector connects to a control system, local alarms or exhaust fans. It also comes with an alarm-disable mode to disable alarms for testing, repair or calibration.
