Industrial LVDT sensor

The LVDT sensors of the R-812 series are suitable for a large number of industrial applications including severe operating conditions (temperature, radioactive environment, etc...). The measurement ranges are from ± 1.25 mm to ± 250 mm. The sensor body is resistant to corrosion and abrasion. The vibration resistance is 20 g at 2 kHz, the operating temperature range is -55°C to +135°C as standard and can be extended to 200°C as an option.

The output signal (unamplified) of the R-812 sensor is proportional to the position of the core inside the sensor body. The connection system consists of a bundle of insulated wires in an axial Teflon sheath. Other advantages are typical of the LVDT: excellent accuracy (non-linearity: 0.15% of the PE), infinite resolution, long life and no drift.
