Cerabar M PMC51 and PMP51 pressure transmitters for gas, steam and liquids

Cerabar M PMC51 and PMP51 pressure transmitters are suitable for accurate absolute and gauge pressure measurements in gases, steams or liquids and level, volume or mass measurements in liquids.

Standard accuracy is 0.15% with 0.075% accuracy available as an option. Long-term stability is 0.1% of upper range limit (URL)/year and 0.25% of URL/five years.

The transmitters are available with ceramic or metal process isolating diaphragm seals which allow the sensors to work in temperatures up to 400ºC or pressures up to 413 bar.

Outputs include 4-20 mA, 4-20 mA with HART, Profibus PA and Foundation Fieldbus.

The transmitters can be programmed to calculate level, volume and mass in any tank shape by means of a programmable characteristic curve that accounts for level, pressure, density of the medium and gravitation constant. The system can compensate for foam formation, agitators, screen fittings and liquid gases.

The intrinsically safe (Ex ia/IS) transmitters can be used in hazardous areas, including FM/CSA Division 1 installations. Options are available that make the transmitters suitable for gaseous oxygen, hydrogen and ultrapure gas environments, as well as paint shops.

The PMP51 has a piezoresistive measuring cell and a metal welded process isolating diaphragm to handle pressures to 6000 psi.

The PMC51 has a capacitive measuring cell and a ceramic process isolating diaphragm, and provides a metal-free PVDF connection.

All versions are compliant with ASME-BPE, have 3A and EHEDG approvals, can be used for process pressure monitoring up to SIL2 and are certified to IEC 61508 Edition 2.0 and IEC 61511 by TÜV NORD.
