The SANTEST L2DT is a non-contact, absolute linear displacement transducer using inductive sensing with a copper sleeve, designed for high-temperature applications up to 150°C. It provides analog output of 0-10 V or 4-20 mA and two open-collector contact outputs rated at 0.1 A, 30 V DC. Sensor stroke ranges from 100 to 500 mm, with non-linearity of ±0.5% F.S. typical and resolution better than ±0.1% F.S. The sensor housing has IP67 protection and can withstand up to 21 MPa pressure. The system includes a probe, cable up to 20 m in length, and a separate controller (L2DTC-4) that drives a 10 kHz excitation signal. Operating temperature for the sensor is -40°C to +150°C, and the controller operates from 0°C to +60°C. The probe body is nickel-plated brass with an SS304 rod, and the cable is heat-resistant and shielded.
SANTEST's Linear Inductance-L Transducer L2DT is a sensor of which inductance changes with displacement of the copper sleeve covering a sensor probe. 10kHz sine wave excites the solenoid coil of the L2DT sensor. It generates the short ring effect as a copper sleeve covers a sensor probe. The magnetic flux of the short ring effect makes decrease inductance of solenoid coil. When the copper sleeve covers the whole sensor probe, the short ring effect is the strongest and the value of inductance becomes the smallest. Calculating the change of this inductance, it is possible to detect the position of a copper sleeve.
