Pascal CI4 serie

How do these sensors work?

Are you looking for a pressure sensor that is suitable, for example, for measurements of aggressive measuring materials or at high process temperatures? The Ci4 series of sensors is Labom's flagship. The high-quality pressure transmitter can be used to measure pressure & differential pressure. The sensor has a large, high-resolution display. This is especially useful for reading and programming.

Cleaning from the outside is also possible because an IP69K rating is available with this sensor. The transmitters of the Pascal Ci4 series can be divided into two categories: the sensors for relative / pressure sensors (Ci41) and the sensors for the differential pressure, level and flow measurements (Ci43).


The Ci4 sensors are widely used in (petro) chemical installations. The high reliability, SIL2 and ATEX certification and the robust design make the transmitter suitable for this environment. In Biotech & Pharma installations, the Ci4 is also widely used due to the sanitary design.

The large turndown (1:00) is used to narrow the measuring range without losing accuracy. In addition to the flexibility that this offers, it can also mean a considerable saving in the number of spare parts. The transmitter is also very suitable for panel mounting due to the large display and the various mounting options.
