LBW-420-LEL
Ammonia Leak Detector

The LBW-420-LEL ammonia gas detector is a versatile detector offering that rounds out the Cool Air Inc. ammonia gas detection system product line. The LBW-420-LEL is specifically purposed for the detection of high ammonia concentrations in the event of a catastrophic leak in industrial ammonia applications. To do this, a catalytic bead sensor, with a range of 0-10%, monitors for potentially explosive levels of ammonia, creating a notification and response prior to achieving the lower explosive limit (LEL) of the target gas. It has all the features you need for emergency response, in any harsh environment. 

One of its main features is noticeable at first glance, with its highly visible digital readout for displaying the ammonia concentration in %NH3. This detector can also seamlessly integrate with your existing PLC or automation control system via its 4-20 mA analog output. Finally, the LBW-420-LEL comes equipped with three output relays that can be used for activating emergency ventilation, de-energizing pumps, compressors, motors and other equipment.

Features

• Bright LED display, indicating NH3 concentration in Real Time
• Gas sensor mounted externally, ensuring highest probability for immediate detection
• Annual calibration requirement, process is simple and quick, reducing maintenance costs
• Industry standard 4-20 mA output for connecting to controllers and PLCs
• Three relay output contacts for stand-alone operation
