For a pressure sensor of the same class with a ceramic diaphragm, use PMC11. If the pressure range exceeds 4MPa or explosion protection is required, use PMP21 / PMC21. For hygienic applications, use PMP23.
The Cerabar PMP11 is the most economical compact pressure transmitter. It uses a piezoresistive sensor with a gauge pressure measuring range of 400 mbar..40bar. The PMP11 uses high-quality materials (e.g. 316L) and meets the measurement conditions in the process industry. It can be used in standard applications in the process industry.
Advantages
Ultra-compact design and user-configurable measuring range for simple, time-saving installation and setup in the plant
Reference measuring accuracy of 0.5% with high long-term stability and high repeatability, ensuring high-quality process monitoring in standard processes
Strict use of 316L material and passing all tests during production guarantee wide process compatibility
Application areas
Pressure transmitter with a fully welded metal sensor for gauge pressure measurement of gases or liquids.
Process connection: thread
Process temperature: -25...+85°C (-13...+185°F)
Process pressure: 400 mbar...+40 bar (6...600 psi)
Measuring accuracy: ±0.5% of full scale
