Gas Relief Line Vent
Gas Detector LBW-50-RLV
Gas Detector LBW-50-RLV-%

Having gas detectors on your vent lines can alert safety personnel, allowing swift action to reduce the potential exposure to the surrounding community and the onsite workers in the event of a gas release.

The LBW-50-RLV relief line vent (RLV) detector has the basics needed to suit most of the needs your vent line application requires. We retrofit a standard LBW-50 detector with a 2-inch schedule 80 fitting and potted electronics. The detector can sense any gas in your relief line vent header, regardless if it is coming from a weeping valve or during a release due to system overpressure. The front panel contains five LEDs that illuminate when ammonia gas is detected. Two of the LEDs are paired with the detector's alarm set points, and it comes equipped with three output relays for connecting to alarm beacons/horns and auxiliary equipment. This is packaged in a bright, safe yellow enclosure, allowing quick identification.

• Front panel LEDs indicate progressive gas concentration.
• Capable of sensing gas at very low concentrations to catch weeping valves.
• Annual calibration requirement, reducing maintenance costs.
• RLV fitting mounted on back of detector or configured as remote sensor.
• Same features as standard LBW-50

The LBW-50-RLV detector is manufactured in the USA and comes with our standard three-year limited warranty.
