Precise, Sustained Measurement in High Temperatures with New Miniature TE Connectivity Position Sensor

Compact LVDT with low mass core withstands temperatures up to +200 degrees Celsius (+392 degrees Fahrenheit)

HAMPTON, Va. November 19, 2015 –TE Connectivity (TE), a world leader in connectivity, has added the MHR-T Series of high-temperature, miniature linear variable differential transformers (LVDTs) to its line of linear displacement sensors.

With a diameter of only 9.5 mm (3/8-inch), these high-reliability transducers accurately measure displacement in space-constrained applications including process controls, automation and robotics as well as chemical plants, hydraulics and power turbines.

Efficiently manufactured under a strict ISO 9001 quality system, these LVDTs operate in temperatures from minus 20 degrees Celsius up to 200 degrees Celsius (minus 4 degrees Fahrenheit up to 392 degrees Fahrenheit) and are available with a wide range of strokes from ±0.025 to ±1 inch. The new series also features a rugged, corrosion-resistant aluminum construction that withstands elevated temperatures as well as high shock and vibration.

The high output sensitivity of the MHR-T enables interfacing with nearly all signal conditioners and conditioning circuits. These miniature position transducers enable precise measurement in a diverse set of applications, including cylinder position feedback, materials testing machines and many other space-restricted, high-temperature installations.

The low core weight of the MHR-T significantly reduces its influence on the attribute being recorded for accurate measurement in applications requiring higher displacement speeds. It also reduces mechanical stresses to preserve the structural integrity of the core actuation assembly for long-term, reliable measurements.

The frictionless design provides several benefits, most notably truly infinite resolution and null position (zero) repeatability, both of which provide exceptional stability and repeatability. It also contributes to the long life of the MHR-T, as there are no parts that can wear out or cause failure provided the core is properly aligned in the application.

With the core separated from the coil, the new position sensors can isolate caustic or pressurized media from the coil assembly via a non-magnetic barrier to enhance reliable, long-term operation. The windings in the MHR-T Series include a high-temperature, flexible resin for exceptional protection against harsh environments.

Each unit comes with a calibration certificate and is compatible with TE’s full line of LVDT signal conditioners. AC operation for all models ranges from 2 kHz to 20 kHz.
