The FHPA26 series of AC output LVDT position sensors are designed for high reliability requiring extremely high-pressure applications while operating in the harsh environments required for deep sea applications. These sensors are made of special high-pressure materials and can operate at pressures up to 350 Bar.
The FHPA26 series of high pressure and seawater resistant LVDT position sensors offer excellent performance and are available in custom ranges up to 300mm.
When equipment is submerged in the ocean for an indefinite period of time, it is critical to choose instrumentation that is reliable, and the FHPV26 series of LVDT position sensors are designed with wet-pluggable underwater connectors with protection ratings up to IP69K.
ABEK Sensors has a wealth of experience in the design and manufacture of LVDT sensors and can customize the mechanical and electrical design of sensors to meet the user's design requirements.
