Differential pressure sensor GBEL-LED

piezoresistiveanalogwall-mounted

The differential pressure measuring instrument GBEL-LED offers highquality measurement with flexible options based on a piezo-resistive sensor. It comes in a plastic housing for wall mounting (enclosure rating IP 54), wired ready for connection. With its easily readable digital display and the continuous analog output signal (0-10V or 4-20 mA) the GBELLED is particularly suited for monitoring and controlling differential pressure in HVAC applications. Upon ordering you can select the output signal (0-10V or 4-20 mA) and the measuring unit (e.g. PA, KPA, inch w.c., mbar, mm of water…). In case of major pressure fluctuations both the output signal and the response time of the display can be dampened. The electrical connection is a M16 cable gland with cage clamps, the process connections are two nozzles for tubing with a nominal width of 4 MM (inner diameter) and 6 MM (outer diameter). The measuring instrument is calibrated for vertical mounting with the process connections pointing downwards. Optionally available: square-root output signal (and display) for indicating volume flow and/or two adjustable set points with zero-potential switch-over contacts. Violation of the set limit values is visualized by two red LEDs below the digital display. The limit values can be programmed individually and independently via keys at the backside of the digital display.
