Introduction

The P118 family of probes has measuring ranges from 0 mm to 50 mm with a variety of options such as connector or cable outlet, ball and socket mounting. This probe is used for displacement or position measurement under particularly difficult conditions. The P118 inductive displacement transducer is a simple and cost-effective way to achieve accurate and complex displacement measurement. Electrical integration is facilitated by a number of options for the analogue output e.g. 0.5 to 4.5 Vdc, ± 5Vdc or 4-20mA. The sensor can be supplied with 5VDC, 24VDC or with a bipolar supply of ±5VDC or ±15VDC. The P103 has very good linearity and infinite resolution. The bandwidth is 10 kHz.

Mounting and measuring principle

The fixed part (body) of the sensor is fixed by means of a ball joint or a mounting flange. The movable part, corresponding to the displacement measurement, can be actuated by a spring (feeler) that pushes it permanently against the part to be measured. It can also be connected by a ball joint or by the threaded hole at the end of the rod. The measurement is made without contact between the fixed part and the moving element, by induction, allowing a very high number of cycles, MTBF > 350 000 hours.

Applications

The LIPS P118 sensor is recommended for :

  • Displacement measurements
  • Vibration measurement
  • Displacement and control monitoring
  • Position monitoring
  • Laboratory measurements
