LGW-2G-… Pressure Switch
The differential pressure switch LGW-2G-…-SIL is suitable for monitoring over-, differential- and underpressure of air, gaseous, non-aggressive media in air ducts, in supply or exhaust air units.
Description
In combination with Ex-i switch type EXL-IR-9170 with intrinsically safe circuit, the sensors can be used in hazardous locations in zone 1 and 2. The switching amplifier may only be installed and operated in non-hazardous atmospheres.
The sensor has a passive, potential-free switch contact.
