Flush faced pressure sensors

09 December 2022

With a flush sensing face, with no dead space to allow the build-up of contaminants, PL15xx pressure sensors from ifm electronic are said to perform reliably even with viscous media such as adhesives and sealants.

Developed primarily for use in high pressure systems, PL15xx sensors are resistant to damage caused by transient pressure peaks. They also incorporate a sealing system that prevents fluid media, even at high pressure, from entering the threaded area of the process connection. This not only eliminates the possibility of leakage, but also prevents cross-contamination in systems that are used with more than one type of medium.

With a G½ process connection, ifm’s new PL15xx pressure sensors are available in eight versions with measuring ranges from 0 to 2.5 bar up to 0 to 160 bar. Accuracy, determined according to DIN IEC EN 62828-1, is ± 0.5% or better, while long-term stability is ± 0.1% or better. The sensors are suitable for use with media over a wide temperature range of -25 to +110°C.

PL15xx sensors provide either a conventional two-wire analogue output or a digital IO-Link output. When IO-Link is used, the sensors provide both pressure and temperature data which, in many applications, can save money be eliminating the need for a separate temperature sensor. A cumulative total of operating hours can also be accessed via the IO-Link connection.
