Project Overview
A water treatment and industrial process facility in East Africa required a reliable and stable pressure measurement solution for critical process monitoring under fluctuating operating conditions. The application demanded high accuracy, long-term stability, and compatibility with standard industrial control systems (4–20 mA + HART).
Customer Requirement
- Stable pressure measurement in the range of -1 to 10 bar
- High reliability for continuous industrial operation
- Compatibility with existing control system (HART communication)
- Resistance to process fluctuations and harsh working conditions
- Easy integration into existing instrumentation infrastructure
Selected Solution
To meet the application requirements, we supplied the following model:
Endress+Hauser CERABAR S Pressure Transmitter
Model: PMC71-KHM9/1Q7 (PMC71-ABA1PBMPBAA)
Key Features
- Measuring range: -1 to 10 bar
- Output: 4–20 mA with HART communication
- High precision ceramic sensor technology
- Excellent long-term stability and overload resistance
- Suitable for demanding industrial process environments
- Robust design for water and general process applications
Engineering Value
The CERABAR S PMC71 series ensures:
- Stable and drift-free measurement performance
- High resistance to pressure spikes and overload conditions
- Reliable signal transmission for PLC/DCS systems
- Reduced maintenance cost and downtime
Result
The solution was successfully selected and supplied as a direct replacement/upgrade for the customer’s pressure monitoring system. It significantly improved measurement stability and system reliability in continuous operation conditions.
Conclusion
This project demonstrates the reliability of Endress+Hauser CERABAR S pressure transmitters in water treatment and industrial process applications, especially where accuracy and long-term stability are critical.
