Hoffmann + Krippner provides custom, pressure-resistant sensors for hydraulic valves

In cooperation with the German manufacturer INELTA, Hoffmann + Krippner now offers a family of robust and customer-specific hydraulic valve position sensing solutions used in a wide range of industries such as oil & gas, power generation or wherever a precise valve position in hydraulic applications is required.

The LVDT sensors are fitted into existing hydraulic valve assemblies, and by using electromagnetic coupling, measure the core placement inside valve. They can also be used as continuous position sensors. For continuous sensing applications, the sensors can be mounted to the hydraulic valve in the end position behind the magnet or in an intermediate position in between the magnet and the valve block. The LVDT sensors can be also be coupled to the valve anchor with a non-magnetic core extension.

Depending on the version, the sensors can detect a measurement range of ± 1.2 mm to ± 20 mm. They are available with either current or voltage output (4 to 20 mA / 0 to 10 VDC).
