using a reference measurement
A hydraulic press is fitted with a load cell for monitoring the pressing force. This sensor must be checked regularly, because the system is operated in shifts under difficult conditions. The only option is to calibrate the sensor in its installed state, because internal friction forces arising from guides etc. can have an effect on the measurement result. The 8527 load cell, bundled with the TRANS CAL 7281, proves a practical measurement combination for portable use under these circumstances.
