IMP+ I.S. Pulsar ATEX Level Sensor

IMP+ I.S. is a combined transducer and controller in one self-contained unit and is I.S. certified to ATEX EEx ia IIC T4 and IECEx.

IMP+ I.S. benefits from a specially designed digital echo processing technique and is available in three versions, 3m, 6m or 10m range. The full IMP range is available with the wetted parts in PVDF build alternative for corrosive or aggressive applications.

Simple installation

IMP+ I.S. is easy to install, just simply screw into a 1.5" or 2" universal fitting (a 1.5" or 2" adapter is available). Programming is also straightforward by simply using the LCD display and integral keypad featured on the IMP+ I.S.
