Robust G 1/2 pressure transmitter with hygienic approval for small pipes

The ifm PM15 pressure transmitter is a first in this category. ƒ An ideal solution for hygienic production plants or where clogging is a concern ƒ Maintenance-free PEEK sealing concept for G 1/2 fitting ƒ A robust, tried-and-tested ceramic measuring cell free from pressure transducer liquids ƒ Resistant to high-pressure cleaning with aggressive cleaning agents ƒ High temperature resistance and high protection rating (IP 67, IP 68, IP 69K) ƒ Approved to industry-wide hygienic standards, such as: FDA, EHEDG, EC1935 and 3A ƒ Integrated temperature measurement via IO-Link removes need for multiple instruments ƒ 4 to 20 mA and digital IO-Link communication without A/D or EMC losses. Hygiene has top priority in many process-technical installations, in the food, beverage or pharmaceutical industries, for example. This also applies to sensor technology used in a multitude of applications. The new pressure sensor PM15 with a G 1/2 external thread sealing cone connection which meets the requirements for all approvals to industry-wide hygienic standards, is ideal for such applications. Perfect for pressure and temperature monitoring The PM15 is perfect for pressure and temperature monitoring in mixing, dosing and heat exchanger systems. Cost savings are achieved by using the G1/2 sealing cone instead of the 1˝ connection with clamp fittings for pipe installations. It provides for elegant and simple installation on pipes, in particular smaller pipe sizes where compactness is critical. Ideal for hygienic production plants The new PM15 pressure sensor is ideal for hygienic production plants or where clogging is a concern. It has

a unique flush sealing concept. This allows for the hygienic integration of small ceramic capacitive measuring cells in small pipes, for example, in dosing and filling systems, which was not previously possible. With the

G 1/2 thread, it can be installed without requiring expensive adapters. Flush fitting makes it possible to use viscous media and guarantees optimum results for CIP processes. For each sensor, a factory certificate is available for free download.

Maintenance-free and robust On the process side, the sensor is maintenance-free because it has no elastomer seal. The flush and robust ceramic measuring cell is resistant to pressure and vacuum shocks and to impact by abrasive sub stances. The sensor can be used for viscous prod ucts that would typically clog pressure transmitters with small measuring ports. The final value of the meas uring range is from 2.5 bar to 40 bar. The sensor is resistant to medium tem
