Hygienic and process pressure sensors (or transmitters) are crucial components in various industries, particularly in food and beverage, pharmaceuticals, biotechnology, and chemical processing. These sensors are designed to measure and transmit pressure data, ensuring the safe and efficient operation of industrial processes. Here's an overview of each type. 

Hygienic Pressure Sensors

With Hygienic pressure sensors smooth, crevice-free surfaces prevent the buildup of bacteria and contaminants. The sensors are easy to clean and often designed for Clean-in-Place (CIP) and Sterilize-in-Place (SIP) processes. Compliance and adherence to industry standards such as FDA, EHEDG, and 3-A Sanitary Standards. Hygienic pressure sensors are specifically designed to meet the stringent requirements of industries where cleanliness and sanitation are paramount. These sensors are typically used in:

Food and Beverage Industry: Ensuring sanitary conditions to prevent contamination.

Pharmaceuticals and biotechnology: Maintaining sterile environments for drug production and biological processes.

Cosmetics: Ensuring product purity and consistency.

Process pressure sensors

Process pressure sensors are build to withstand harsh environments, including extreme temperatures, high pressure, and corrosive substances. Their high accuracy and reliability are essential for maintaining process control and safety. The versatility of process pressure sensors make them suitable for a wide range of industrial applications. Process pressure sensors are used to monitor and control pressure in various industrial processes. They are critical in:

Chemical processing: Ensuring safe and efficient operation by monitoring pressure in reactors, pipelines, and storage tanks.

Oil and gas: Monitoring wellhead pressure, pipeline pressure, and refining processes.

Water treatment: Ensuring proper pressure levels in filtration and distribution systems.

Things to consider selecting a suitable sensor

For any sensor, it is important to consider the pressure range, accuracy, sensitivity, range and conditions. Especially for our Hygienic and Process pressure sensor category, we would like to provide the following tips to help you choose the right sensor for your project or application:

• Compliance with hygiene standards
• Choose appropriate materials: The sensor’s wetted parts should be made of materials that resist corrosion, such as stainless steel (e.g., 316L), to ensure longevity and maintain hygiene. Ensure the materials are compatible with the media being measured and any cleaning agents used.
• Surface finish: Opt for sensors or transmitters with a polished surface finish (e.g., Ra < 0.8 μm) to minimize the risk of bacterial contamination and ensure easy cleaning.
• Sanitary process connections: Choose sensors with hygienic process connections, such as Tri-Clamp, DIN 11851, or aseptic fittings, that ensure a secure, leak-free, and easy-to-clean interface with your system.
• Ease of installation: Consider how the sensor will be installed and whether it fits seamlessly into your existing process lines, minimizing downtime and ensuring a tight seal.
• Operating temperature range: Ensure the sensor can operate within the temperature range of your process, including during sterilization cycles, without degradation.
• Temperature Compensation: Opt for sensors with built-in temperature compensation to maintain accuracy across varying process temperatures.
• Signal uutput type: Choose a sensor with an output that matches your control system, whether it’s analog (4-20 mA, 0-10V) or digital (e.g., HART, Profibus).
• Environmental protection: Consider sensors with high ingress protection ratings (e.g., IP67, IP69K) to ensure they withstand washdowns and harsh operating environments.
• Ease of maintenance: Select sensors that are easy to disassemble, clean, and reassemble, minimizing process downtime. Consider models with self-diagnostic features to simplify maintenance.
