LVDTs allow measurements at higher displacement speeds

Measurement Specialties has introduced its series of miniature, high-reliability linear variable differential transformers (LVDTs) for measurements at higher displacement speeds. The MHR Series measures 3/8" or 9.52mm in diameter and can be applied in settings with space restrictions. The series is designed with a lightweight core to reduce inertia and mechanical stress, and can be used in environments where excessive core weight could affect the motion of the measurement.

Applications include satellite mirror focusing systems, UAV and helicopter targeting and sight systems, as well as oil and gas equipment, pneumatic actuators, medical ventilators, wire-bonding machines, and material and soil testing.

The miniature transducers come in stroke ranges from ±0.005" to ±2" with ±0.25% linearity. The MHR's operating temperature ranges from -55 degrees C to +150 degrees C, with an option for 220 degrees C operation, and an excitation frequency up to 20kHz.

The close electrical coupling between the coil and the core allows the LVDTs to offer high output sensitivity, providing a sufficient signal to interface with various signal conditioning circuits.

The rugged transducers feature stainless steel housings, as well as imperial or metric threaded cores.

The MHR series windings are vacuum impregnated with a formulated, high-temperature flexible resin that provides protection against hostile environments such as high humidity, vibration, and shock.

Mild radiation resistant versions, as well as high pressure versions up to 20,000 psi submersed in oils (vented housing) are available upon request.

The MHR series is compatible with Measurement Specialties' full line of LVDT signal conditioners. All units come with a calibration certificate.
