The LIPS P111 is an accurate and robust inductive linear displacement transducer for harsh industrial applications. A hardened version of the P101, the P111 features a reinforced 12.6mm diameter shaft for increased vibration resistance and excellent service life (MTBF > 350,000 hours).

Measurement ranges are specifiable to the centimetre in the range 0-5mm to 0-800mm. The resolution is infinite and the excellent frequency response > 10 kHz allows vibration studies. The transducer is DC powered, and incorporates conditioning electronics for a voltage or 4-20mA output signal compatible with any analogue acquisition system.

The analogue output signal is linear with the absolute position (non-linearity: < ± 0.25mm for 100mm displacement, optionally reduced to ± 0.1mm)


The sensor body is made of stainless steel. The fixed part (body) of the P111 transducer is fixed by means of an M5 ball joint or a flange. The movable part, corresponding to the displacement measurement, can be connected either by a ball joint or by an M5 rod. A probe option is available up to 300 mm in length. Clamps are also available.

The electrical connection is either a connector (IP65) or a cable (IP67), in axial or radial position. Two potentiometers allow fine adjustment of zero and gain. Several types of output signals are available :

ATEX version / Intrinsic safety

The LIPS X111 is the ATEX version of the P111. The LIPS X111 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 X101 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 X101 data sheet.
