PCM1350 Flat Diaphragm Pressure Transmitter for Hygienic and Aseptic Applications

In hygienic industries such as food processing, beverage production, pharmaceuticals, and bioengineering, pressure measurement accuracy and sanitary compliance are critical to product quality and consumer safety. Conventional pressure transmitters often present challenges including measurement dead zones, cleaning difficulties, and limited long-term stability.

The PCM1350 Flat Diaphragm Pressure Transmitter is specifically engineered for high-hygiene applications. With a robust aseptic structure and stable measurement performance, it provides a safer, more accurate, and more efficient solution for sanitary process control.

Hygienic Structural Design for Aseptic Environments

316L Stainless Steel Flush Diaphragm

The PCM1350 adopts a hygienic-grade 316L stainless steel isolation diaphragm. The flush-mounted diaphragm features a surface roughness of Ra < 0.38 μm, effectively minimizing medium adhesion.

Direct welding of the process connection eliminates additional gaskets, ensuring a dead-zone-free structure. The fill fluid is hygienically certified, preventing medium residue and cross-contamination. This design fully complies with aseptic requirements in food and pharmaceutical production environments.

High Accuracy and Long-Term Stability

Designed for demanding industrial applications, the PCM1350 offers:

• High-precision measurement performance

• Strong anti-interference capability

• Excellent long-term stability

Both zero and span are adjustable, allowing flexible calibration to maintain measurement accuracy under varying environmental conditions.

Adaptability to High-Temperature and Complex Media

The transmitter supports multiple aseptic process connections and can withstand process temperatures up to 150°C. It operates reliably in high-temperature steam environments and is suitable for viscous, paste-like, or other challenging media.

Its structural design ensures consistent performance under diverse working conditions.

Simplified Installation and Maintenance

The PCM1350 provides various electrical connection options and a flexible structural configuration. Its compact and practical design enables convenient on-site installation and reduces maintenance workload, helping lower overall operational costs.

Application Fields

Thanks to its hygienic design and stable performance, the PCM1350 is widely applied across multiple industries:

Food and Beverage Industry

Used for pressure monitoring of liquids and pastes throughout the entire production process—from raw material handling to final filling—ensuring accurate measurement in aseptic environments.

Pharmaceutical and Bioengineering

Suitable for pharmaceutical manufacturing and biotechnology R&D applications. It supports vacuum pressure detection, such as vacuum transfer pump monitoring, as well as fluid pressure control under strict hygiene and accuracy requirements.

Other Industrial Applications

In addition to hygienic sectors, the PCM1350 performs reliably in hydropower, chemical processing, water supply systems, oil & gas, compressed air, steam, and powder media measurement, adapting to both standard and aseptic process conditions.

Core Advantages of PCM1350

Hygienic Design Minimizing Contamination Risk

The 316L stainless steel diaphragm and food/pharmaceutical-grade fill fluid, combined with a dead-zone-free structure, meet stringent aseptic processing standards and support compliance audits.

High Accuracy with Stable Performance

Low hysteresis, rapid response, and strong anti-interference capability ensure reliable data output. Temperature drift performance is maintained within:

• ±3% FS (0°C–60°C) for 35 kPa range

• ±1.5% FS (-10°C–70°C) for other ranges

This guarantees accurate measurement under fluctuating conditions.

Flexible Configuration and Efficient Deployment

Customizable measuring range, output signal, electrical connection, and optional heat sink (three fins available for media above 100°C) provide flexibility for diverse applications. Easy installation and simplified wiring reduce maintenance costs and enhance operational efficiency.
