Measuring Short Displacements Reliably
The W1ELA/0 displacement transducer in plunger version enables precise measurement of short displacements directly during the process.
W1ELA/0 Displacement Transducer: Inductive Displacement Measurement in Machines and Systems; Nominal (Rated) Measuring Range +/– 1 Mm
The extremely compact W1ELA/0 displacement transducer consists almost entirely of just the coil body and plunger. This allows the sensor to be perfectly placed in the relevant machine, system, or test bench. This is further supported by the widely approved temperature range of the sensor from –55° C to +130° C. The W1ELA/0 displacement transducer can be used for reliable acquisition of the nominal (rated) displacement, moving outward from the center position in both directions.
The coil body contains two measuring coils arranged one behind the other, which together form an inductive half bridge. This must be completed in a 4.8 kHz carrier frequency amplifier to form a full bridge circuit.
Nominal (rated) measuring range: 0…±1 mm
