Sanitary Pressure Sensing Solutions with PC112K: Customized Flush Diaphragm Sensors for Food, Beverage, and Pharmaceutical Industries

In industries where hygiene, accuracy, and reliability are nonnegotiable—such as food, beverage, and pharmaceuticals—the choice of pressure sensors plays a pivotal role in ensuring both process safety and product quality. The PC112K Flush Diaphragm Pressure Sensor is purposebuilt for these demanding environments. With customizable parameters, advanced sanitary design, and robust performance across diverse applications, it delivers precise pressure and level measurements even in the presence of viscous or sticky media.

 Industry Challenges and the Need for Sanitary Pressure Sensing

Food and pharmaceutical processing environments require components that maintain the highest levels of cleanliness and compatibility. Standard pressure sensors often struggle with media like syrups, creams, dairy, or viscous pharmaceutical suspensions. The risks of contamination, scaling, or clogging can result in process inefficiencies or costly downtime.

The PC112K sensor addresses these challenges with a flush diaphragm design and 316L stainless steel housing, which ensure easy cleaning, minimal residue buildup, and resistance to corrosion. The use of foodgrade silicone oil further ensures safe operation even in sensitive sanitary environments.

 Adaptable Sensor Configurations for Various Industrial Applications

The PC112K supports a wide pressure range from 100kPa to 10MPa, enabling integration across multiple process points—be it for lowpressure beverage tanks or highpressure pharmaceutical reactors. It offers gauge, absolute, or sealed gauge pressure references to suit system requirements.

The sensor is also available with customized electrical outputs and connection interfaces, ensuring easy adaptability across existing equipment in different industries. Whether you're automating a food production line or managing realtime level monitoring in fermentation vessels, PC112K has a configuration to match your equipment needs.

 Application 1: Dairy and Milk Pasteurization Systems

In milk processing plants, precise monitoring of pressure in pasteurization pipelines and tanks is critical to ensure product safety and compliance. The PC112K excels in this environment by maintaining stable readings, even in the presence of proteinrich milk or foam. The flush diaphragm prevents bacterial buildup and supports CIP (CleaninPlace) and SIP (SterilizeinPlace) routines without sensor removal.

Recommended Parameters:  

 Pressure Range: 0–600 kPa  

 Pressure Reference: Gauge  

 Electrical Output: 10V excitation with goldplated KOVAR pin  

 Compensated Temp: 0℃~60℃  

 Application 2: Beverage Fermentation and Storage

In breweries and soft drink production, fermentation and storage tanks require realtime monitoring of both level and pressure to maintain consistent product quality. The PC112K sensor, mounted with a sanitary clamp, provides stable and driftfree measurements regardless of the carbonation or fluid viscosity.

Recommended Parameters:  

 Pressure Range: 0–1 MPa  

 Pressure Reference: Gauge or Sealed Gauge  

 Operating Temp: 10℃~70℃  

 Filling Oil: M20  

 Application 3: Chocolate, Syrup, and Viscous Product Processing

Thick media like chocolate or glucose syrup can cause severe clogging in traditional pressure sensors. The PC112K’s flush diaphragm ensures smooth measurement surfaces with no internal cavities where residues can accumulate. Its robust diaphragm and antivibration capability (20g) make it ideal for highspeed mixing environments.

Recommended Parameters:  

 Pressure Range: 0–1.6 MPa  

 Input Impedance: 2kΩ~5kΩ  

 Electrical Output: Constant current excitation (1.5mA)  

 Response Time: ≤1ms  

 Application 4: Pharmaceutical Mixing Vessels and Reactors

Pharmaceutical processes require sterility and accuracy. In mixing vessels and reactors, pressure monitoring is essential to control batch reactions and prevent contamination. The PC112K sensor’s absolute pressure configuration and high insulation resistance (≥200MΩ/250VDC) ensure safe, longlasting operation even in sterile environments.

Recommended Parameters:  

 Pressure Range: 0–2.5 MPa  

 Pressure Reference: Absolute  

 Compensated Temp: 10℃~70℃  

 Electrical Connection: Silicone soft wire for EMI resistance  

 Application 5: Cosmetics and Personal Care Production

Lotions, creams, and gels are notoriously difficult to monitor using traditional sensors. The PC112K offers a hygienic and reliable solution by allowing direct contact with the medium without disrupting the product’s consistency or cleanliness. Its durability (10⁷ pressure cycles) ensures a long lifecycle, reducing maintenance costs.

Recommended Parameters:  

 Pressure Range: 0–1 MPa  

 Pressure Reference: Gauge  

 Housing Material: 316L Stainless Steel  

 Shock Resistance: 100g/10ms
