Hardened inductive probe - 0-5 to 0-50 mm - IP67 - Diameter : 19 mm - ATEX option

Introduction

The LIPS P112 inductive probe allows precise measurement of position or displacement over ranges from 0-5mm to 0-50mm. Incorporating inductive technology, the P112 is designed for the harshest environments: operating temperature: -40 to +257°F, IP67, excellent durability (MTBF > 350,000 hours), vibration resistance of 10g.

The analogue output signal is proportional to the absolute position (non-linearity: < ± 0.25mm for 100mm displacement, optionally reduced to ± 0.1mm). The resolution is infinite, the frequency response very high (> 10 kHz).

Installation

The sensor body is made of stainless steel, with a diameter of only 19mm. The fixed part (body) of the sensor P112 is fixed via a thread. The moving part, corresponding to the displacement measurement, is actuated by the spring in the sensor body. Clamps are also available.

The electrical connection is either a connector or a cable, in axial or radial position. Two potentiometers allow fine adjustment of zero and gain. The transducer is powered by DC voltage, and incorporates conditioning electronics for a voltage type output signal :

ATEX version / Intrinsic safety

The LIPS X112 is the ATEX version of the P112. The LIPS X112 is certified Intrinsically safe Ex II 1G and Ex ia IIC T4 Ga (Ta= -40°C to 80°C) . The measurement performance and size are identical. The X112 must be used with an ATEX galvanic barrier, like the X005. The output signal is analogue, type 0.5 - 9.5V or 4-20 mA See LIPS X112 data sheet.
