Diaphragm monitoring system with HART® protocol
Part number: Model DMSU21SA
Applications
- Hygienic pressure measurement for the pharmaceutical industry and for aseptic food processing
- Pressure/vacuum measurement on pipelines, fermenters, bioreactors and vessels as well as with processing and transport of high-quality media
- Suitable for the production of active pharmaceutical ingredients (API)
- For the monitoring of processes with sterile steam
- For gases, vapour; liquid, pasty, powdery and crystallising media
Special features
- Double-diaphragm system prevents contamination of process and environment
- Hygienic process connections in different designs
- Signal transmission and configuration with only one cable per measuring location
- Minimal installation costs, even with retrofitting
Description
The model DMSU21SA diaphragm monitoring system fulfils the constantly growing requirements for process monitoring on plants for sanitary applications. With the HART® protocol, not only the measuring signal, but also the status of the integrated diaphragm monitoring can be transmitted, as required, to the process control. The system architecture with integrated diaphragm monitoring bridges the gap between digitalisation and process reliability.
With the patented diaphragm monitoring, a monitoring element is mainly used for electrical/digital signal transmission of the diaphragm condition. In addition, the diaphragm condition is displayed on a dial with red/green areas.
In the event of a diaphragm rupture, a second, internal diaphragm ensures the reliable separation of the environment and the process. A fluid inside the system, which is explicitly chosen to suit the particular measuring requirement, hydraulically transmits the pressure to the pressure measuring instrument. Depending on the application, the system fill fluid is FDA- and also USP-compliant.
The diaphragm monitoring system can be supplied with all common process connections for sanitary applications and fulfils the applicable standards for them, e.g. EHEDG, 3-A and ASME BPE.
