Product Description

Overview: Dead weight testers are high precision fundamental pressure standards that define the derived unit of pressure directly from the fundamental units of mass, length and time following the formula p = F/A.

Application: The dead weight testers are applicable in a very wide variety of pressure calibration and measurement tasks. Appropriate configurations are available for use in primary standards laboratories and as reference instruments on the workshop.

 

Feature

  • Test differential pressure transducer under the high static pressure
  • Piston and cylinder is made of tungsten carbide, which makes minimized errors caused by deformation and temperature effects.
  • The piston operation position shown by displacement sensor
  • One side of dead weight tester pistons can be used as gauge pressure calibration solution

 

Specification

Uncertainty:

  • Uncertainty under the static pressure status (by using two pistons):  2Pa5×10-7×P1Pa×10-4×△P, P is static pressure, P is differential
  • One side of pistons /can uses as gauge pressure calibration, uncertainty is ±0.01% reading.

Media: Air (System installed oil-gas separator, media in piston system is transforming oil, the media to unit under test is air)
