Dwyer Instruments indicating transmitters are sensors providing an electrical transmission output for remote indication of the pressure ratings. These units provide a 4-20 mA process output signal, a robust NEMA 4X enclosure to handle impact loads and a large LCD screen which can be programmed to display pressure, velocity or flow rates. They also facilitate simplified programming via a Menu key which enables the user to select: security level; English or Metric engineering units; and pressure, velocity or flow ratings. Choose from a broad range of these indicating transmitters available in 0-10 V, 0-5 / 0-10 V, 4 to 20 mA and 4-20ma output range on Raptor Supplies, an authorised Dwyer Instruments distributor.
