The IFM PM1709 is a hygienic pressure sensor developed for demanding applications in the food and beverage industry, where strict hygiene requirements must be balanced with durability and precision. Its flush-mount design and Aseptoflex Vario connection ensure aseptic integration into process systems, making it an ideal solution for handling viscous media, liquids with suspended particles, as well as standard liquids and gases.

At the core of the PM1709 is a ceramic-capacitive pressure measuring cell, a proven technology that delivers excellent long-term stability, measurement accuracy, and durability. Ceramic elements offer strong resistance to corrosion, aggressive cleaning agents, and abrasive media, making them highly suitable for food and beverage production environments. Additionally, the capacitive design provides excellent overload resistance, ensuring reliable operation under fluctuating or high-pressure conditions.

The sensor’s Aseptoflex Vario process connection with G 1 external thread offers hygienic, flexible, and secure installation. This system eliminates crevices where residues might accumulate, ensuring compliance with hygiene standards and supporting effective clean-in-place (CIP) and sterilise-in-place (SIP) cleaning procedures. The flush-mount construction further reduces the risk of contamination by ensuring that no dead space remains, making the PM1709 particularly effective for use with sticky or particle-rich products.

The PM1709 is designed to withstand medium temperatures ranging from –25…150 °C, giving it broad suitability across a wide range of processes. From refrigerated storage and cold-fill applications to heat-intensive processes such as pasteurisation, sterilisation, and cooking, the sensor provides reliable measurement performance. This temperature flexibility allows manufacturers to standardise on a single sensor type across different stages of production.

In terms of media compatibility, the PM1709 is especially effective for viscous products such as sauces, dairy, creams, and fruit-based preparations, as well as liquids containing suspended solids. It is equally reliable in monitoring standard process liquids and gases, making it a versatile solution for multipurpose production lines.

Electrical reliability is reinforced through the use of gold-plated contacts, which resist corrosion and provide stable signal transmission over the sensor’s service life. This ensures dependable performance even in humid or chemically aggressive environments typical of food and beverage processing facilities. While the PM1709 does not feature integrated temperature monitoring, it excels in delivering robust, precise pressure measurements that support process efficiency, product quality, and operational safety.

In summary, the IFM PM1709 is a durable, hygienic, and precise pressure sensor designed for the food and beverage industry. Featuring a ceramic-capacitive measuring element, Aseptoflex Vario connection, flush-mount hygienic design, and wide operating temperature range, it is built to handle both standard and challenging media. For engineers and plant operators requiring reliability, hygiene, and adaptability, the PM1709 is a trusted and versatile solution.
