RKI Instruments PS 2 [73-1020RK-01] Combustible Gas Monitor 24 VDC

The RKI Instruments PS 2 combustible gas monitor is a multi-purpose, stand alone unit with an MOS (metal oxide semiconductor) for long lasting and low maintenance detection at the LEL or PPM levels of many gases or vapors. Since the PS 2 sensor is a general hydrocarbon sensor, it is not specific to any particular gas It has two alarm levels for increasing gas or vapor levels, at the PPM level for detection of many solvent vapors, or for LEL level detection of flammable vapors. Each alarm level activates a 12 amp relay inside the unit, and terminals are provided for wiring the relay to activate an external alarming device or some other device such as a ventilation fan.

This RKI Instruments unit is housed in a durable plastic enclosure with flanges provided for wall mounting and is designed with easy access wiring hubs on the bottom of the unit. The front of the PS 2 contains three lights; Pilot, Alarm 1, and Alarm 2. An internal audible alarm (85 db) is also built in which activates in a gas alarm condition. The standard PS 2 is supplied with the gas sensor located on the end of a 30 foot cable (other cable distances are also available). Each unit is powered by 24 VDC as standard (115 VAC or 48 VDC versions optional) and the AC version comes complete with a 6 foot power cord.

Common applications for the RKI Instruments PS 2 combustible gas monitor include battery storage and charging locations, petrochemical plants, refineries, water and wastewater treatment plants, gas, telephone and electric utilities, manufacturing facilities, steel, automotive, HVAC and buildings on landfill.
