The PDS815 Sanitary Pressure Transmitter is a smart hygienic pressure transmitter designed for pressure, differential pressure, level, and flow measurement in food processing, chemical, pharmaceutical, and clean process applications. It can measure liquids, gases, or steam and convert the measured signal into 4–20 mA DC with HART communication, or optional PROFIBUS PA, FOUNDATION Fieldbus FF, WirelessHART, and ZigBee output signals.
With ±0.04% FS accuracy, 100:1 rangeability, long-term stability of ±0.1% FS over 10 years, intelligent diagnostics, simulation functions, and multiple corrosion-resistant material options, the PDS815 is suitable for hygienic process pressure measurement where clean connection, reliable sealing, and smart communication are required.
The PDS815 sanitary pressure transmitter is designed for pressure measurement in hygienic and clean process systems. It is suitable for applications where the process connection must reduce residue, avoid dead zones, and support cleaning or sterilization requirements.
Compared with ordinary threaded pressure transmitters, a sanitary pressure transmitter normally uses a hygienic process connection such as clamp, flange, or other clean-interface design. This makes it more suitable for media that require clean operation, such as food liquids, beverages, pharmaceutical fluids, purified water, process steam, and compatible chemical media.
The PDS815 supports 4–20 mA DC with HART communication, PROFIBUS PA, FOUNDATION Fieldbus FF, WirelessHART, and ZigBee communication options. Through compatible communication devices, users can perform remote configuration, monitoring, diagnostics, simulation, and maintenance.
The PDS815 hygienic pressure transmitter can be selected with different output signals according to the automation system and site requirements.
| Output / Communication | Description |
|---|---|
| 4–20 mA DC + HART | Standard analog output with HART digital communication |
| PROFIBUS PA | Digital fieldbus communication for process automation systems |
| FOUNDATION Fieldbus FF | Fieldbus communication for advanced field instrument networks |
| WirelessHART | Wireless communication option for smart field instrument networks |
| ZigBee | Wireless communication option for specific wireless monitoring systems |
For most food, pharmaceutical, and industrial process applications, 4–20 mA with HART communication is commonly used because it works well with PLC and DCS systems while still supporting smart configuration and diagnostics.
The PDS815 is designed for hygienic process installations where cleanability, sealing reliability, and reduced residue are important. It is suitable for food, beverage, pharmaceutical, and clean utility systems.
The PDS815 can be used for pressure-related measurement tasks including pressure, differential pressure, level, and flow, depending on the selected structure, process connection, and installation method.
The transmitter can be selected as PDS815G gauge pressure transmitter or PDS815A absolute pressure transmitter according to the process measurement requirement.
The PDS815 provides ±0.04% FS accuracy, supporting stable pressure measurement in hygienic and industrial process control loops.
The maximum rangeability of 100:1 allows flexible span setting for different pressure ranges and operating conditions.
The transmitter provides long-term stability of ±0.1% FS over 10 years, helping reduce recalibration frequency and maintenance workload in continuous production.
The PDS815 supports intelligent diagnostic and simulation functions. These functions help users check device status, verify output signals, and simplify commissioning or troubleshooting.
Configuration can be performed through HART, PROFIBUS PA, FOUNDATION Fieldbus, WirelessHART, ZigBee, or compatible communication devices depending on the selected output.
Different wetted materials can be selected for different process media. For chemical, pharmaceutical, or food-related applications, material compatibility, sealing material, and process cleanliness should be confirmed carefully.

The PDS815G gauge pressure transmitter measures pressure relative to atmospheric pressure. It is suitable for tank pressure, pipeline pressure, pump outlet pressure, filtration pressure, clean utility pressure, and hygienic process pressure measurement.
The PDS815A absolute pressure transmitter measures pressure relative to absolute vacuum. It is suitable for vacuum systems, sealed vessels, evaporation processes, sterile process systems, and applications where atmospheric pressure variation should not affect measurement accuracy.
The PDS815 can be used in food and beverage production lines for pressure monitoring of liquids such as water, milk, juice, syrup, beverage base liquids, sauces, and other compatible food-grade media.
It is suitable for process points where ordinary threaded pressure ports may cause residue, cleaning difficulty, or hygienic concerns.
Used in pharmaceutical process lines, purified water systems, clean utility systems, fermentation processes, mixing systems, and sterile process equipment where stable pressure measurement and clean installation are required.
For direct sanitary applications, process connection type, diaphragm surface, sealing material, and cleaning requirements should be confirmed carefully.
Suitable for compatible chemical media where a hygienic or flush process connection is preferred. For corrosive media, diaphragm and process connection materials should be selected according to chemical compatibility.
Can be applied to clean steam, process steam, compressed air, purified water, and other utility systems. For high-temperature steam, temperature limits, sealing material, and installation accessories should be checked.
The PDS815 can be used for pressure-based level or pressure monitoring in sanitary tanks, mixing vessels, storage tanks, and process containers, depending on installation position and process conditions.
When configured appropriately and installed with suitable process connections or primary elements, the PDS815 can support differential pressure or flow-related measurement applications in hygienic process systems.
In food and pharmaceutical industries, many process systems require CIP and SIP procedures.
| Term | Meaning | Description |
|---|---|---|
| CIP | Clean-in-Place | Cleaning the process system without disassembly |
| SIP | Steam-in-Place | Sterilizing the process system with steam without disassembly |
For hygienic pressure transmitter applications, the process connection and wetted structure should support cleaning requirements and reduce areas where residue may remain.
The PDS815 sanitary pressure transmitter can be selected for applications where clean process connection, stable pressure measurement, and smart signal output are required. For strict sanitary applications, connection type, surface finish, gasket material, and temperature resistance should be confirmed according to project requirements.
When selecting a PDS815 sanitary pressure transmitter, the following details should be confirmed:
Depending on the site conditions, the PDS815 sanitary pressure transmitter may require accessories such as:
For food, beverage, and pharmaceutical applications, gasket material, connection standard, surface finish, and cleaning compatibility should be confirmed before ordering.
| Item | Standard Pressure Transmitter | PDS815 Sanitary Pressure Transmitter |
|---|---|---|
| Process Connection | Usually threaded or industrial flange | Hygienic process connection |
| Cleanability | Not always suitable for sanitary systems | More suitable for clean process applications |
| Residue Risk | Higher with small pressure ports | Lower with suitable hygienic connection |
| Typical Media | Water, air, oil, gas, steam | Food liquids, pharma fluids, clean utilities, compatible chemicals |
| Typical Industries | General industrial process | Food, beverage, pharmaceutical, clean process systems |
| Selection Focus | Pressure, material, connection | Cleanability, gasket, diaphragm, process connection, cleaning temperature |
For general industrial pressure measurement, a standard pressure transmitter may be sufficient. For food, pharmaceutical, clean utility, or applications requiring hygienic installation, the PDS815 sanitary pressure transmitter is more suitable.
