The first hygienic pressure sensors on the market with a G 1/2 fitting, products in the new PM15 range from ifm electronic provide a convenient and dependable solution to the problem of measuring pressure in small pipes, such as those often found in dosing and filling systems. Thanks to their G 1/2 thread, the sensors can be installed quickly and easily without the need for expensive adaptors and, as they use oil-free ceramic sensing cells, they are ideal for applications in the food, pharmaceutical and other hygiene-sensitive industry sectors.
PM15 pressure sensors feature I/O-link connectivity, which ensures accurate transmission of measurements even in electrically noisy environments and allows the sensors to additionally provide temperature measurements. In many applications, this eliminates the need for a separate temperature sensor, thereby saving money and reducing complexity. The sensors also provide a 4 to 20 mA analogue output for pressure measurements only.
Since they need no elastomer seal and incorporate a pre-mounted PEEK sealing ring, PM15 sensors are virtually maintenance free. All types have stainless-steel bodies with an IP67 or better ingress protection rating, depending on the method of installation. They are highly resistant to pressure and vacuum shock, and to the effects of abrasive substances. In addition, they are suitable for use with media over a wide temperature range of -25 to +125 ºC (<1hr: 150ºC). These features, together with their robust construction, make the new sensors ideally suited for use in even the most demanding environments.
ifm electronic is currently offering the PM15 G 1/2 hygienic pressure sensor with ranges from 0 to 2.5 barg through to -1 to 40 barg and all have a minimum of 5 x measuring range overload resistance.
