Model 511 - Hammer Union Pressure Transmitter

The Viatran Model 511 hammer union pressure transmitter is among the most advanced in this field. It has an output of 4-20 mA, with a 2 inch 1502 fitting. It is approved for use in hazardous locations. It is ideal for such situations because of its unique design features, created to fulfill direct feedback requests from actual operators. Thus it has such advantages as a voltage-powered tool to calibrate the shunt, the ability to detect and track spikes in pressure, using software from HART^® Communicators or DevCom2000-Lite. The whole sleek device is housed in an extremely rugged housing which can resist high vibrations and extreme impact amounting to abuse, while still maintaining standard parameters of performance.
