Comparison Test Pump
Pressure comparators
are used as working pressure standards and allow rapid, accurate calibration
of pressure instruments by comparing an instrument on a pressurised test
pump with a test standard of known accuracy and span.
Application: Calibration of pressure Gauges, Transmitters, Transducers, Recorders.
Operating Principle:
When fluid Pressure generated by a screw pump acts on the Test Gauge,
the pressure in the circuit will be determined by the reading in the test
gauge and this pressure is compared with the respective readings of the
gauge under test.
 |
Range: | Various models from 0-1000 kg/cm2. |
|
|
Accuracy: | Depends on the accuracy of the master gauge. We manufacture gauges of accuracy + 0.25% and + 0.5%. |
|
|
Operating Medium: |
Air, Water or oil as the operating fluid as per application. |
|
|
Type of Pump: |
Bulit-in screw
pump of adequate capacity to generate pressure by turning a handle
permitting easy and accurate settings.
|
|
|
Wetted Parts: | MS or SS304. |
