High strength LVDT probe

The GA-750 series LVDT touch probe sensors provide instantaneous position measurement with excellent accuracy, high sensitivity and infinite resolution. The measuring ranges are from ± 1.27mm to ± 50mm.

The output signal of the GA-750 is proportional to the position of a core inside the sensor body, the core being moved by the probe. The output signal is either unamplified, a 0-10VDC voltage, a +/-10VDC voltage or a 4-20 mA current.

The sensor body is made of high-strength, corrosion-resistant nickel-iron alloy. The electrical connector is directly mounted on the sensor either axially or radially. 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 as an option.
