926230 Solartron Metrology LVDT

Optimum Series LVDT Sensors_x000D_ The optimum series of LVDT sensors are high performance sensors ideal for use in process control and research applications, the 9.52 mm diameter of these sensors make them an ideal choice where space is limited._x000D_ Large radial bore clearance_x000D_ 9.52 mm body diameter_x000D_ Stainless steel case material_x000D_ IP65 ingress protection_x000D_ Note_x000D_ Range of accessories also available:_x000D_ 775-3877: universal joints kit_x000D_ 775-3871: ball tip and adapter_x000D_ 775-3880: return spring_x000D_ 775-3883: return spring_x000D_ 775-3887: return spring_x000D_ 775-3896: return spring_x000D_ 775-3899: return spring_x000D_ Linear Variable Differential Transformers (LVDT)_x000D_ 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;_x000D_ No wear problems as with potentiometers_x000D_ Infinite resolution, high accuracy and linearity_x000D_ No friction introduced into the measured system_x000D_ Available in ranges from ±1mm to ±50mm_x000D_ Note_x000D_ RS LVDT's datasheet Stock No. 232-4049 is available on request.
