The Ralston Instruments DCAP-PV pump along with a FieldLab calibrator and an absolute pressure transmitter can generate a vacuum to reach necessary test points. The pump needs to be easy to use as most calibration technicians will calibrate quite a few transmitters each day.
The FieldLab pressure calibrator from Ralston Instruments is said to perform well in Class 1 Division 1 hazardous locations for pressure calibration, testing or validation. There are test modes for high speed logging up to 128 times per second, hydrostatic testing and templates for pressure calibration of pressure transmitters and gauges that the user whether the device being tested passed or not.
With the Ralston Instruments PSV Test suite of software and hardware, it is said to be possible to conduct the test and record most of the information on a FieldLab calibrator. After the test is completed the data is then transferred electronically to a PC where a certificate with graphs, customer data, tag data and other required information can be created.
