Pressure Transducers – Secondary Standard

Harwood Engineering offers strain gauge cells as secondary standards for pressure measurement (read more on the difference between secondary and primary standards). This device is typically sold with a Precision Digital indicator and a 10 point primary calibration with certification records.


The strain gauge cell is extremely reliable and durable. These rugged pressure transducers are suitable for general field applications.  When calibrated against our deadweight tester, the strain gauge cell can serve as a secondary standard reference instrument.  If used as a secondary standard in a laboratory setting, we generally recommend semi annual calibration against the dead weight tester.
