Calog Loadcell

The Calog Loadcell Calibrator is ideal for testing 4 and 6 wire loadcells, checking insulation breakdown, weighing system calibration and simulation.

It can test a loadcells' zero balance, input resistance, output resistance, bridge balance, 50V DC insulation test from bridge to shield, bridge to housing and shield to housing.

The Calog - Loadcell Calibrator is a hand-held precision calibrator specifically designed for load cell testing, including insulation breakdown, and weighing system calibration or stimulation. Simply connect a strain-guage load cell to the spring terminals and press "TEST LOADCELL". The backlit graphics will display four or six wire, zero balance, input or output resistance and bridge balance. It can then carry out a 50 VDC insulation test form bridge to shield, bridge to housing and shield to housing.

For system testing and calibration the Calog - Loadcell Calibrator can simultaneously measure mV (with mass display), excitation voltage and mA. In source mode, used for load cell amplifier pre-calibration testing, it can source mV (with mass display), measure excitation and measure mA. In simulate mode it sources a mA signal to the control room or SCADA. The display can be in mA, mA and mass or mass and mA.
