Radiation hardened LVDT position sensor
ABEK has extensive design expertise in nuclear radiation-hardened LVDT. The underwater high-temperature nuclear radiation-resistant position sensors and neutron irradiation-resistant position sensors, have been deployed in multiple large-scale scientific facilities.
Spring Loaded LVDT
The LVDT measuring head has a built-in frictionless LVDT structure, and its core is directly connected to the measuring axis, which can output a voltage signal that is linearly proportional to the displacement, are ideal for test measurements.
High-temperature resistant LVDT displacement sensors are produced with special materials and processes, and the temperature resistance is 200℃ for FHTA19 series, 300℃ for FCTA10 series, 400℃ for FCTA15 series, and there are high-temperature resistant nuclear radiation resistant ATX-XR series.
Signal Conditioner
The signal conditioner is compatible with LVDT, RVDT and half-bridge LVRT sensors, with field switchable output voltage and current signals, selectable excitation frequency and adjustable filtering bandwidth.
DC output LVDT position sensors have built-in demodulation circuits for easy connection to PLCs, signal acquisition equipment, etc.
ABEK is flexible in customization options for numerous deep-sea/underwater applications, e.g. deep-sea submersibles, underwater steering gears, submarine pipeline monitoring, derrick monitoring, mooring devices, etc.
Valve, spool position sensors
ABEK offers LVDT sensors for a wide range of valve position measurements, including hydraulic valves, feedback valves, nuclear spray valves, proportional valves, servo valves, etc.
Miniature LVDT Position Sensors
FCXA10 series LVDTs can be used at high pressure of 140MPa and high temperature of 200°C. These miniature LVDTs can be used in rock triaxial high temperature and high-pressure testing machines, hydraulic equipment, embedded robots and harsh downhole environments.
Explosion Proof position sensors
FLAR19 Series LVDT Linear Position Sensors are certified intrinsically safe and explosion proof.Ex ia ⅡC T6 GaIt can be safely operated in hazardous places with explosive gases, vapors and dusts.
RVDT Angular Displacement Transducers
RVDT adopts the same differential transformer principle as LVDT, i.e., the rotation of mechanical parts is transferred to the shaft of the angular displacement transducer, which drives the spoiler/core connected to it, changes the induced voltage/inductance in the coil, and outputs voltage/current signals proportional to the angle of rotation.
Aerospace LVDT-RVDT Position Sensors
From test equipment to airborne and airborne use.ABEK SENSORSThe LVDT/RVDT sensors are qualified for use under different conditions and environments.ABEKOffering single channel, dual channel, triple redundancy, quad redundancy, from small modifications to full customization.
