Portable Hydraulic Testers

Posted on March 14, 2013

Stauff is launching its new SDMKR reversible flow device for monitoring hydraulic components and systems in mobile hydraulics systems at bauma 2013. The device allows the simultaneous measurement of flow, pressure and temperature and makes it possible to determine the performance of pumps, motors, valves or cylinders, along with complete systems.

Stauff said that the portable device is compact and robust – with a steel frame, removable protective cover and shockproof displays. The SDMKR incorporates a flowmeter with a visual display and a built-in thermometer, as well as a loading valve that makes it possible to safely increase the working pressure gradually and continuously up to 420 bar in order to provide a realistic simulation of normal machine operation. Two integrated burst discs act as internal safety mechanism, effectively protecting the device against accidental overpressure, the company said.

The operation of the hydraulic tester is mechanical and the device can be used independently of any internal or external power supply, thus providing high flexibility.  Unlike many other comparable devices, the SDMKR also permits flow in the reverse direction, Stauff said.

The company is also premiering its new PPC-04-Plus hand-held hydraulic tester for the measurement of pressure, temperature, flow rate, frequency and speed in mobile and industrial hydraulic systems. Succeeding the PPC-04 tester, the new device is available either with two inputs for analogue sensors or with a CAN interface for connecting up to three digital sensors. Both versions provide automatic sensor recognition. The CAN sensors also offer the advantage of lower susceptibility to interference due to digital data transmission, despite a maximum cable length of up to 50 meters.
