Accurate hydraulic testing

Data-logger reading hydraulic pump

We are pleased to introduce a new piece of equipment for our Service Department - a handheld data-logger.  The image to the right shows this equipment attached to a hydraulic pump on our in-house test rig.

Recording accurate dat

The data-logger will also be used for on-site visits
and will assist our hydraulics engineer whilst
completing the initial inspection.  Accurate data
will be recorded for analysis and to produce test
certificates.  Our hydraulics engineer will be
working in a safer environment and more
efficiently helping to save our customers valuable
time.

The data-logger is a recently launched product from Webtec Products Ltd and is ideal for diagnostic applications as well as for permanent installation on small hydraulic test benches. It can be used to measure any combination of flow, pressure, temperature, speed and custom analogue inputs.  It is a valuable tool for diagnostic testing as well as preventive maintenance, verifying component settings, pinpointing poor system performance and measuring pressure differentials.


P & R Hydraulics can repair most makes of hydraulic pumps, motors and valves. We have an in-house workshop and test-rig and also offer a local on-site service for the East Anglia region.  Please contact our Service Department on 01603 424880 for more information.
