Objective of Pressure Laboratory
The main objectives of the pressure laboratory are to establish, maintain and upgrade national primary standards of pressure measurements compatible to international standards through research and development.
The aim of the pressure laboratory is to realize,maintain and disseminate the derived SI Units of pressure(Pa).The laboratory has been providing apex level calibrations in different pressure regions and maintains traceability of pressure measurements at international level.
The main activities of the laboratory are participate inter comparisons in the field of pressure and to assure international traceability,provide calibration service to calibration laboratories , testing laboratories and to industry.
Pressure is a derived Unit combining the SI Units of Mass,Length and Time.
SI Unit - Pa=Nm-2
1) Hydraulic Pressure Standards
The hydraulic pressure standard in the range up to 200 Mpa
Hydraulic Pressure Balance
2)Pneumatic Pressure Standards
The Pneumatic pressure standard in the range up to 7 Mpa
Pneumatic Pressure Balance
Existing facilities of pressure laboratory
The following secondary pressure standards have been established in the pressure laboratory and are internationally compatible Existing instruments and their ranges are shown in Table.
|Pneumatic pressure||High Pressure pneumatic controller.||70 MPa|
|Hydraulic pressure||Dual range Dead Weight Tester.||120 MPa|
|Blood Pressure||Blood pressure stimulator and Tester
(High accuracy model)
|0 - 400mmHg|
Following calibration services provided by pressure laboratory from existing pressure facility.
1. Hydraulic pressure gauges - up to 200 MPa
2. Pneumatic pressure gauges - up to 7 MPa
3. Blood pressure meters (Mercury sphygmomanometers , digital blood pressure apparatus , aneroid apparatus)
