Cerabar PMP43 Hygienic Pressure Transmitter

Cerabar PMP43 is a compact hygienic pressure transmitter for accurate gauge and absolute pressure measurement of liquids and gases in sanitary process applications. Featuring a 316L welded metal diaphragm with zero dead space, it offers 0.1% standard accuracy (0.075% Platinum), long-term stability of 0.1% URL/year, and a wide measuring range from 400 mbar to 100 bar with 20:1 turndown. Compatible with Tri-Clamp, DIN 11851, Varivent, SMS and other sterile connections, it supports 4–20 mA HART and IO-Link communication, and carries 3-A, EHEDG, ASME-BPE, NSF/ANSI 61 and global Ex certifications-ideal for food & beverage, dairy, pharmaceutical and potable water service.

The Cerabar PMP43 is a compact, highly reliable pressure transmitter purpose-built for hygienic process connections. Its crevice-free, welded metal diaphragm and polished 316L wetted surfaces clean quickly and completely, which is what makes it the preferred pressure measurement choice in food, beverage, dairy, brewery and pharmaceutical service, where cleanability and materials traceability are non-negotiable.

Despite its small footprint, the PMP43 delivers laboratory-grade performance: reference accuracy down to 0.075%, a turndown of up to 20:1, and long-term stability of just 0.1% of URL per year. It measures both gauge and absolute pressure in liquids and gases, can be supplied with remote diaphragm seals, and communicates over 4–20 mA with HART or IO-Link for digital diagnostics - all inside a hygienic 316L stainless housing designed to be cleaned and CIP/SIP-in-place.

• Sanitary by construction - The process diaphragm is welded to the process body, eliminating O-rings, gaskets and dead legs where bacteria could harbour. Surfaces are polished and easy to drain and clean.
• Proven metal-diaphragm accuracy - The robust 316L ceramic-cell-free metal membrane gives precise, repeatable readings on liquids and gases; reference accuracy reaches 0.075% on the platinum option.
• A hygienic connection for every pipe - Factory options cover Tri-Clamp, DIN 11851, DIN 11864-1, NEUMO, Varivent, SMS, DRD and universal-adapter fittings, plus standard threads (G, R, MNPT, FNPT) and flanges (DN25–DN80, NPS 1"–3").
• Wide measuring range & turndown - Ranges from 400 mbar up to 100 bar (6–1450 psi) with a minimum span of just 20 mbar (0.3 psi) and a turndown of up to 20:1 - one transmitter covers many duties.
• Robust across temperature - Process temperature spans −40…+130 °C (optionally −20…+200 °C) and ambient −40…+85 °C, suiting CIP, SIP and steam-clean cycles.
• Digital, future-ready communication - 4–20 mA with HART or IO-Link enables in-system commissioning and remote diagnostics without opening the process.
• Explosion protection available - Non-Ex (11.5…45 V DC) or intrinsically safe Ex ia (12…30 V DC) power supply for hazardous sanitary areas.
• A complete approval portfolio - ATEX, FM, CAN/US, IECEx, INMETRO, NEPSI and UK Ex for functional safety and hazardous-area use; EN 10204-3.1 and NACE MR0175 for materials; NSF/ANSI 61, ACS and KTW for drinking-water duty.

• Dairy and UHT processing, milk and cream lines
• Beverage and brewery - filling, blending, CIP return monitoring
• Food processing and cooking / evaporator vessels
• Pharmaceutical and biotech water, WFI and clean-steam loops
• Bottling and packaging machine pressure monitoring
• Drinking-water distribution where NSF / ACS / KTW is required

Important - please read before requesting a quotation. The PMP43 is not configured through an online selection tool. Because hygienic variants differ in diaphragm and housing material, process connection, gasket/seal, options and certifications, we quote the PMP43 only against the exact model code or the nameplate of your existing transmitter.

To receive an accurate offer, please provide one of the following:

• Full order code / model designation - the complete model code printed on the nameplate or in your original order.

• A photo of the product nameplate - for a replacement, a clear photo of the nameplate is enough for us to read the code.

Q. Can the PMP43 be CIP and SIP cleaned in place?

A. Yes. The welded, crevice-free diaphragm and polished 316L wetted surfaces are designed for clean-in-place and steam-in-place cycles; process temperature reaches +130 °C standard and +200 °C by option.

Q. Is it suitable for both gauge and absolute pressure?

A. Yes. The PMP43 covers gauge and absolute pressure measurement of liquids and gases across ranges of 400 mbar to 100 bar with a turndown of up to 20:1.

Q. Which hygienic process connections are offered?

A. Tri-Clamp, DIN 11851, DIN 11864-1, NEUMO, Varivent, SMS, DRD and universal-adapter fittings, in addition to standard threads and DN/NPS flanges.

Q. What accuracy and stability should I expect?

A. Reference accuracy is 0.1% standard or 0.075% platinum, with long-term stability of 0.1% of URL per year (0.2% over 5 years, 0.25% over 10 years).

Q. Can I get an offer without an existing model code?

A. For a replacement we need the exact code or a nameplate photo. For a new installation, provide the media, pressure range, hygienic connection and required certificates and we will recommend the correct variant.

Q. Does it support digital integration?

A. Yes - 4–20 mA with HART or IO-Link, plus explosion-protection (Ex ia) power options for hazardous sanitary areas.

Because every PMP43 is application-specific, pricing is prepared only from the exact model code or nameplate. Send us your model designation, a nameplate photo,and our engineers will confirm availability and issue a firm quotation.
