Datasheet

New Tek Sensor Solutions has introduced the HT-1000 LVDT Position Sensor that offers a 1,000°F (538°C) continuous operating temperature rating and resistance to high radiation levels of 100Mrad. The HT-1000 Position Sensor meets the demands of specialty materials testing in autoclaves to determine dimensional stability and long term behaviour by measuring expansion, contraction and strain rates.

Additionally, the displacement sensor is used in nuclear power plants and test laboratories to determine fuel rod behaviour by measuring its expansion and contraction.

Available in high pressure configurations to 3,000psi, the HT-1000 LVDT also delivers position feedback for nuclear fuel rods and control rods in power generation applications.

To minimise thermal sensitivity over a wide temperature range, the Model HT-1000 Position Sensor provides a ratiometric output processed by dividing the secondary difference voltages by the sum to greatly reduce thermal error.

Available in sizes from ±0.500" (±12.7mm) to ±1.0"(±25.4mm), the HT-1000 Position Sensor operates with high resolution, high sensitivity of 0.25mV/V/.001", and linearity of less than ± 0.5% full range typical.

This AC-operated sensor operates with a DIN-rail mounted signal conditioner that provides voltage, 4-20mA current, or RS-485 digital output based on user requirements. NewTek also offers ratiometric signal conditioners to maintain lower thermal sensitivity with high linearity.

Signal conditioners operate remotely while the HT-1000 LVDT operates in extreme environments.
