Adjustable differentialpressure switches Electronic pressure transmitters

Differential pressure transmitter 986 This series has an IP 65 metal housing and is designed for industrial applications. Standard pressure transmitter 980 Digital pressure gauge SensWitch Display P2 990 This universal series with LCD display and optional relay output is designed for installation in control panels and switchboards. There is IP 20 protection on the front. Differential pressure transmitter 984M The adjustable differential industrial pressure switches of the series 930.8 x Climair The electronic pressure transmitters with analog current or voltage output signal are used mainly for pressure measurement in industrial processes as well as for monitoring air flows at filters and blowers. They measureoverpressure, vacuum or differentialpressures of gaseous, non-aggressive media from -1 bar to 12 bar, whereby the lowest pressure ranges are at 0...+-100 Pa. The standard pressure transmitter in the IP 50 plastic housing is available with plug or cable connection. The pressure connection is designed as a pipe connection. This differential pressure transmitter in the IP 54 plastic housing, optionally with LED display, can be fastened directly using molded mounting eyes. The electrical connection is by a cable conduit to screw terminals. The pressure connection to the process is made by means of hose connections.
® and 911.81 are primarily used in ventilation and air-conditioning systems for monitoring the air flow in air ducts, as well as in filters, flaps and fans. They are suitable for air and also other non-inflammable and non-aggressive gases.Various connection sets for ventilation ducts areavailable as accessories. Differential pressure switch 930.8x Climair
® with guide value scale The switching pressure can be adjusted without a manometer at the adjustment knob with the guide value scale. Various versions are available for this with overlapping adjustment ranges of between 0.2 mbar and 40 mbar.The pressure switch is equipped as standard with a transparent cover, protection class IP54. Differential pressure switch 911.81 without guide value scale The switching pressure can be set at the central adjustment screw with a screwdriver. Various versions are available with overlapping adjustment ranges of between 0.4 mbar and 5 mbar.
