Collection: Hydraulic Testers for Pressure, Flow & Temperature

The right hydraulic test equipment depends on which parameters need to be measured. For pressure testing alone, hydraulic test cases with analog or digital pressure gauges are suitable. If the flow rate and hydraulic oil temperature also need to be measured, a hydraulic diagnostic device with the appropriate sensors is required. The required measuring range, available connections, and the hydraulic system to be tested are also important factors.

Depending on the test device, pressure, volume flow rate or flow rate, and temperature can be measured. Pressure measurement alone, for example, is suitable for monitoring system pressure. By additionally measuring the volume flow rate, it is also possible to assess the performance of pumps, valves, motors, and complete hydraulic circuits. Temperature measurement adds another important operating parameter to the diagnosis. Which measured variables are required depends on the specific diagnostic task.

The required measuring range depends on the maximum operating pressure or flow rate of the hydraulic system to be tested. When measuring pressure, the measuring range should be selected so that the expected system pressure is safely within the permissible range of the measuring device. For different applications, hydraulic test cases with various pressure ranges as well as flow meters for different flow rates are available. Therefore, the technical data and target values of the hydraulic system to be tested should be known before making a selection.

Analog hydraulic test gauges are particularly suitable for quick and easy checking of system pressure. They require no electrical power supply and allow for a direct reading of the measured value.Digital test gauges offer additional functions such as min/max display, higher readability and – depending on the version – the storage and documentation of measured values.If, in addition to pure pressure checking, an evaluation or documentation of the measurement results is required, a digital measuring device with a data logger may be the better solution.

Flow measurement is useful when not only the available pressure, but also the actual oil flow rate needs to be assessed.This allows, for example, hydraulic pumps, motors, valves, cylinders, steering systems and complete hydraulic circuits to be checked.In combination with pressure and temperature measurement, flow measurement enables a more comprehensive assessment of the performance of a hydraulic system.Devices with different flow ranges are available for various applications.

This depends on the specific testing device. Various digital hydraulic pressure gauges and hydraulic diagnostic devices are supplied with a factory calibration certificate. For other devices, calibration is not provided or must be checked separately. If documented calibration is required for your application, you should therefore check at the time of product selection whether the device in question is offered with a calibration certificate.
