Solartron Metrology S Series Linear Transducer 30V

Solartron S Series displacement sensors feature a stainless steel body and IP67;sealing coupled with polymer bearings and 6 mm diameter carriers. The transducers keep working accurately and reliably even in wet and corrosive environments.

<0.2% Linearity;Analogue, DC and 4-20mA versions;19 mm diameter stainless steel body;IP67 rated;Excellent measuring range for the body length;Multiple output options with integrated electronics;Large bore to core clearance for ease of installation;Excellent magnetic shielding;Absolute Positioning

These devices comprise a movable nickel iron core and three coils - one for energisation and two for pick-up. They need to be driven by a sine wave to produce an output amplitude and phase directly proportional to the position of the core with respect to the pick-up coils. A phase sensitive detector is required to demodulate the output signal. The main advantages of LVDTs are;

No wear problems as with potentiometers
