Model 521 Hammer Union Pressure Transmitter
521 is Viatran's state of the art hammer union pressure transmitter with industry exclusive features that were developed in direct response to requests from the field. Included in these features is a voltage powered shunt cal, ability to calibrate and track pressure spikes using HART software and packaged in a patented housing which can withstand extreme vibration and abusive impact and still perform to specification.
