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 inches (± 12.7 mm) to ± 1.0 inch (±25.4 mm) and offer high sensitivity, high resolution, and excellent linearity.
