Technical Specifications

General Specifications

Environmental and Installation Conditions

When installing the PMP23, ensure moisture does not penetrate the housing during mounting and electrical connection. For devices with M12 metal plugs, do not remove the protection cap until shortly before electrical connection. Point the cable and connector downwards where possible to prevent moisture ingress from rain or condensation water.-36

Process Connections

The Cerabar PMP23 is available with multiple flush-mounted hygienic process connections:

Sanitary tri-clamp (1-1/2in)

Flush-mounted hygienic connections (EHEDG and 3-A certified)

Flush-mounted thread connections (G1, M24)

G 1 external thread (front-flush)

Model Code Breakdown: PMP23-BA1B1HBWQJ

Endress+Hauser uses a structured product code system to define the exact configuration of each Cerabar PMP23 pressure transmitter. The following breakdown explains the configuration of PMP23-BA1B1HBWQJ:

This configuration delivers the full capabilities of the Cerabar PMP23 platform—absolute and gauge pressure measurement across the complete sensor range, with the added intelligence of IO-Link communication, IP66/69 ingress protection for rigorous washdown conditions, and hazardous area certification for installations requiring ATEX or IECEx approval.

For reference, other typical PMP23 model codes include:

PMP23-AA1N1PB3CJ – Gauge pressure, 0-10 bar range, M12 connector, 4-20 mA output, gauge type-2

PMP23-CAAN1KF3CJ – 0 to 30 psig range, 4-20 mA output with IO-Link, 1-1/2in sanitary tri-clamp connection, 4-pin M12 quick-disconnect-7

PMP23-AA1U1NBWSJ – 0-6 bar relative pressure, 4-20 mA output, G1 process connection, M16 plug connection, IP65-17

Application Fields

The E&H PMP23 pressure transmitter is ideally suited for the following applications:

Food and Beverage Industry

Tank pressure monitoring

Filter pressure differential measurement

Pipeline pressure in sanitary processes

CIP/SIP cleaning pressure monitoring

Pasteurization and sterilization processes

The PMP23 is fully compatible with CIP (Clean in Place) and SIP (Sterilize or Steam in Place) cleaning procedures, ensuring minimal downtime and maximum process availability.

Pharmaceutical and Biotech

Bioreactor pressure measurement

Fermentation vessel monitoring

Sterile filtration systems

Purified water systems

Hygienic Process Industries

Dairy processing

Beverage production (including carbonated beverages)

Brewing operations

Personal care and cosmetic manufacturing

The flush-mounted 316L diaphragm eliminates dead zones where bacteria could accumulate, while the fully welded process connections minimize the use of gaskets, maximizing process safety.-1

Key Benefits

Superior Process Safety

The fully welded process connections eliminate potential leak paths, ensuring maximum process safety without the need for additional gaskets. The stringent use of 316L material throughout the wetted parts provides excellent corrosion resistance and compatibility with aggressive cleaning agents.

Hygienic Compliance

With EHEDG and 3-A certifications, FDA-conformity materials, and compliance with EG1935/2004 regulations, the PMP23 meets the most stringent requirements for food contact materials in the European Union and North American markets.

Washdown Ready

Models with IP69 protection withstand high-pressure, high-temperature washdown procedures common in food processing environments, eliminating the need for additional protective enclosures.

Simplified Installation and Configuration

The ultra-compact construction enables time-saving installation even in space-constrained applications. Customizable measuring ranges allow the device to be factory-calibrated to specific process requirements, reducing commissioning time.

IO-Link for Industry 4.0

Optional IO-Link communication transforms the PMP23 from a simple analog sensor into a smart IIoT device. IO-Link enables:

Remote parameterization and configuration

Real-time access to process values and diagnostic data

Simplified device replacement with automatic parameter download

Reduced inventory costs with flexible device configuration

Reduced Inventory Costs

The PMP23 is suitable for both CIP and SIP cleaning, allowing a single device to serve multiple applications across a facility. This versatility reduces the number of spare parts needed in inventory.

Installation Guidelines

Mounting Dimensions

Refer to the Mechanical Construction section in the Technical Information (TI) document for complete dimensional drawings. The compact form factor allows installation in tight spaces typical of hygienic processing skids.

Installation Best Practices

Do not remove the process isolating diaphragm protection until shortly before installation

Always tighten cable entries firmly

For devices with gauge pressure sensor: if a heated device is cooled during cleaning (by cold water), mount the device so the pressure compensation element points downward or to the side to prevent moisture penetration–

Any orientation is possible; however, orientation may cause a zero point shift

Zero point shift values: Up to +4 mbar when diaphragm points upward; up to -4 mbar when diaphragm points downward–

Electrical Connection

The PMP23 supports multiple electrical connection options:

M12 plug (4-pin) — metal or plastic versions

M16 plug connection (Valve connector ISO4400)

IP65/67 or IP66/69 ratings depending on connection type and model

Why Choose the Endress+Hauser Cerabar PMP23?

The E&H PMP23 pressure transmitter delivers the optimal balance of performance, compliance, and value for hygienic pressure measurement applications. Unlike general-purpose pressure transmitters that require adaptation for sanitary service, the PMP23 is purpose-built with:

No gaskets or crevices where bacteria can accumulate

Materials that withstand harsh cleaning chemicals

Certifications that satisfy regulatory requirements out of the box

Form factor designed for hygienic process connections

For applications requiring the highest level of accuracy or extended temperature ranges, consider the Cerabar PMP51 or PMP55 series. For basic pressure switching applications, the Ceraphant PTP33B offers a cost-effective alternative.
