Digital Pressure Calibrator Model DPI – 2000 of Range 0-100 Bar with Necessary Fittings.
Operation
This calibrator applies the pascal's law in its use. Pressure is applied on the liquid inside the cylinder of the screw pump by the movement of the piston. Pressure gets transmitted to both limbs equally and if master gauge is connected on one limb and a test gauge on the other limb, then both should show the generated pressure equally. If not, the test gauge is adjusted.
Features
•Portable
•Calibration at site
•Suitable for both oil & water
Applications
Testing and calibration of pressure gauges and switches

Operation
A Solid block of Cu – AI alloy is heated upto the set temp and maintained at the set value. Temperature stability and uniformity meets the most stringent service conditions. Temperature probes of different sizes can be tested in the range of from 50°C to 650°C. Use of an Auto tuning controller ensures, that the deviation of the measured valve from set value remain within ± 0.2°C.
