High resistance long stroke LVDT sensor

The HA-750 series LVDT sensors are designed for instantaneous position measurement in harsh environmental conditions, over measurement ranges from ± 1.25 mm to ± 250 mm. The sensor body is made of high-strength, corrosion-resistant nickel-iron alloy, IP68 waterproof. The vibration resistance is 20 g at 2 kHz, the operating temperature range is -55°C to +135°C as standard and up to 200°C for the HATR-750 model.

The output signal (unamplified) of the HA-750 sensor is proportional to the position of the core inside the sensor body. The electrical connector is directly mounted on the sensor either axially or radially. Other advantages are characteristic of the LVDT: excellent accuracy, infinite resolution, long life and no drift.
