Affordable, dependable and virtually maintanance-free. 4-20mA analog output. NEMA 4X enclosure. Alarm, pre-alarm and auxiliary relays. 115/230 VAC, 50/60 Hz, or 24 VDC. Includes TB-100 test bottle The LBW-420 ammonia leak detector from Cool Air Incorporated has all the features you need to protect your personnel and product. It has a solid-state, long-life ammonia sensor that provides fast and accurate detection of ammonia. In addition to the main alarm system, an early warning system gives you time to react before ammonia levels reach full-alarm status. The front panel display indicates ammonia concentration in parts per million and temperature in degrees Fahrenheit (with a temperature sensor installed). Front panel LEDs give you a quick indication of alarm status. The detector has a 4-20 mA analog output for seamless integration with your existing factory systems. It also comes equipped with contacts for communicating with common industry alarm systems. Additional contacts allow the detector to operate auxiliary equipment such as exhaust fans, king valves, compressors, and additional alarm systems. To reduce nuisance alarms, the LBW-420 has a service mode that temporarily disables the detector s relays during service and testing. And to further enhance the value of this detector, Cool Air Incorporated offers these beneficial options: a temperature sensor and alarm relay with programmable set points, a remote ammonia sensor, and a back-up battery to keep your detector operating during power failures all options you would expect from the refrigeration equipment experts!
