High Temperature

HT-1000 Series

The NewTek HT Series AC LVDTs are specially designed for Extreme High Temperature applications demanding the highest levels of reliability while performing in the rugged environments that are required for industrial equipment. These transducers are constructed of special high temperature materials, allowing them to operate up to 1000°F (538°C). The HT Series provide a ratiometric output, allowing their secondary difference voltages to be divided by their sum. This cancels thermal error, providing extremely low thermal sensitivity over a wide temperature range. These HT Series are available from ± 0.500 inch (± 12.7 mm) to ± 1.0 inch (±25.4 mm) and offer high sensitivity, high resolution and excellent linearity.
