ABEK SENSORS’ FHNA19 Series of 19 mm diameter AC-operated LVDTs is designed for a wide range of position measurement applications. These are rugged hermetically sealed sensors, constructed entirely of stainless steel, and intended for general industrial use. The coil windings are sealed against hostile environments to IEC standard IP-68 and electrical termination is through a sealed axial connector. The mating connector plug is supplied with the unit.

Available in ranges of ±3mm to ±250mm, FHNA19 Series feature the high resolution, excellent repeatability, and low hysteresis associated with LVDT technology, as well as the highest sensitivity consistent with good linearity. The maximum linearity error is ±0.25% of full range output using a statistically best-fit straight line derived by the least squares method.

The FHNA19 series offers multiple technical specifications for customer selection. Beyond the options provided in the selection table, comprehensive customization is available based on customer requirements, including radiation resistance, PTFE core wear-resistant liners, thread specifications, cable outlet types, connector types, and numerous other options.

All FHNA19 Series LVDTs will operate properly with any conventional differential input LVDT signal conditioners, but operation with ratiometric LVDT signal conditioning is not recommended. ABEK SENSORS offers a full line of LVDT signal conditioners that will deliver optimum performance from any FHNA19 Series LVDT.
