Transducers For High Line Pressure Applications

RDP Electronics has announced that it has a range of transducers available for high line pressure applications where it is important to measure the differential pressure between two pressure ports.

Applications such as measuring the pressure across hydraulic cylinders, very high pressure filter measurement, or test applications where a very high line pressure or very high overload pressure is called for, can all be addressed with true wet/wet differential transducers.

Versions can allow differential pressure of 4,000lb/in2, for example, even where the line pressure may already be 5,000lb/in2. They are designed for the minimum possible error caused by variations in line pressure. Transducers are manufactured from stainless steel and versions are compatible with a range of fluids and gases.

Transducers Handle Mechanical Shock And Vibration

RDP Electronics has developed a range of LVDT and magnetostrictive transducers for use in the testing of vehicle suspension systems. The transducers have been designed to withstand the type of mechanical shock, vibration and the tough treatment generally meted out during testing of vehicle suspension systems under all road conditions. RDP transducers are available for vehicle suspension movement applications that involve testing of vehicle components as well as ride, handling and even load detection.

RDP has modified LVDTs to operate reliably and accurately in conditions including the presence of high levels of water and dirt, as well as being subject to vibration and shock during road testing in all weather conditions. Typically for test purposes, the LVDTs are mounted through the floor at the rear of the vehicle or through the body components at the front, and are well suited to providing measurement data derived from the range of components under test.

RDP Develops Transducers For Soil Testers

RDP Electronics has developed transducers suitable for use in triaxial soil testers, where ground samples are subject to pressure applied, most commonly by water or oil. A triaxial shear test is used to measure the mechanical properties of many deformable solids, especially soil, sand, clay, and other granular materials or powders.

Design of the transducer calls for a physically small device, preferably with a through bore permitting cleaning when contaminated with debris, and it must be waterproof. RDP has now designed a wide range of transducers with different armature and cable configurations to optimise their suitability inside a triaxial tester chamber.
