MODEL 374 PRESSURE TRANSMITTER

Low Range Differential Pressure, 1000 psi Line Pressure

Viatran’s 374 differential pressure transmitters are extremely accurate and durable units, designed specifically for test applications. The variable capacitance sensing technology provides extremely high overpressure protection, and long range stability, as well as high accuracy of 0.15% BFSL.

The Model 374 measures pressure ranges from 5" W.C. to 100 PSID and provides a 4-20 mA signal. All wetted surfaces, including flanges and diaphragms, are constructed of 316 stainless steel with a sealing Viton® O-Ring for excellent corrosion resistance. A standard 1,000 PSI static line pressure and single side overpressure rating are featured with these transmitters. For applications that require a higher static line pressure rating, 3,000 PSI is available with optional flanges.
Models 374 also features an internal calibration circuit for easy field set-up, a quick disconnect electrical connection and external zero and span controls. A special option called fast response enables the unit to accurately respond to changes in pressure in approximately one tenth of the standard time.These features make the Model 374 ideal for most industrial test and flow applications.
