The SANTEST L2DT is a non-contact, absolute linear displacement transducer designed for high-temperature environments up to 150°C, with an effective stroke range of 100 to 500 mm. It consists of a probe with a copper sleeve, a heat-resistant shielded cable, and a controller, and is rated for a maximum pressure of 21 MPa on the sensor rod. The sensor outputs 0-10 V or 4-20 mA and includes two open-collector contact outputs rated at 0.1 A, 30 V DC. It features IP67 protection, a drive frequency of 10 kHz, a frequency response of 100 Hz, and operates with a +24 V DC supply. The probe is mounted in a cylindrical housing and is constructed with nickel-plated brass and SS304 stainless steel. The cable length is available up to 20 m, and the controller is housed in a DIN 35 mm rail-mountable enclosure.
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.
