With nearly 30 years of experience in the deadweight industry, our technicians at WeberCal provide our customers with confidence that their equipment is in the most capable hands while delivering the full spectrum of calibration, troubleshooting, repairing, and manufacturing of parts for your hydraulic deadweight testers.

Full Service Calibration

Full Service Package includes:

  • Inspect Deadweight Tester for external damage

  • Note any missing parts

  • Complete disassembly of Deadweight Tester

  • Clean internal and external of Deadweight

  • Clean all weights

  • Ensure proper stacking of weights

  • Ensure proper boss and counterbore are in line (if out, correct if possible)

  • Weigh all weights

  • Ensure weights are within factory tolerance/acceptable condition (if out of tolerance, add/remove mass to correct, when possible)

  • Record mass of each weight

  • Replace all O-rings

  • Replace all seals/bearings, if applicable

  • Disassemble piston and cylinder assembly- includes: visual inspection of component parts for wear/damage; ensure table assembly mass is within factory tolerance (correct if needed, when possible); acquire total mass and surface area of piston/cylinder assembly*

*In order to better serve our customers’ needs, WeberCal offers the option to rebuild, repair, or completely replace piston and cylinder assembly

  • Reassemble Deadweight Tester

  • Install new oil

  • Pressure test deadweight tester to meet factory specifications

  • Provide a Certificate of Calibration to include the following:

    • -Mass of all individual weights provided with the unit plus their calculated pressures in PSI, Bar, and kPa

    • -Piston height specification

    • -Total mass required to float 1,000 PSI (or 500 PSI if approx. 3/16 piston diameter, as applicable)

    • (all certificate pressures are calculated utilizing local gravity coefficient of 980.665 cm/sec2. A custom certificate can be provided if given the end user’s specific gravity)

    • Guarantees accuracy of 0.05% of calculated pressure reading.

Also listed:

  • -Serialized identification of all scales utilized in certificate preparation, with expiration dates of those scales calibration.

  • -Serialized identification of the transfer standard (traceable to NIST) with its calibration expiration date.

 **Customer will be notified immediately upon discovery of any discrepancy/component failure and provided a cost estimate of repair/ replacement.
