The HP19 series of LVDT position sensors from Abek Sensors are designed for displacement measurement in high-pressure environments and are ideal for position measurement in pressure vessels such as autoclaves, pressure seal chambers, hydraulic actuators, valve position indicators, etc.

HP19 series LVDT adopts thick-walled stainless-steel pressure-resistant design and can also be customized with 316L or C276 material in strong corrosive environments, with an integral welded sealing structure, which is sturdy and durable, and is very suitable for applications in high-pressure and corrosive environments. This series of LVDTs can withstand working pressures up to 35MPa and high temperatures of 200°C, which is very suitable for applications in high-temperature and high-pressure environments.

The HP19 series LVDTs are available in ±6.5mm, ±12.5mm, ±25mm and are available with US or metric threads. At the same time, the LVDTs have a maximum measurement non-linearity of ±0.25% (full stroke output), which ensures high-precision position measurement.

All models in the HP19 series have an internal magnetic shield to protect the sensor from external magnetic fields. At the same time, this series of LVDT adopts through-plate installation, which has strong resistance to shock and vibration.

In order to facilitate the actual application of the customer, we also supply a variety of accessories to match the sensor, the series of related mounting fixtures, signal processing equipment, cables and other accessories, please contact us for information.
