Product Description

The Endress+Hauser Cerabar PMP43 is a state-of-the-art hygienic pressure transmitter, meticulously engineered to meet the stringent requirements of sanitary process industries. As a core product in E+H’s Cerabar series, it combines high-precision measurement, robust hygienic design, and intelligent functionality, making it the first choice for pressure monitoring in food & beverage, pharmaceutical, biotechnology, dairy, and brewery applications. Whether for routine process control, critical quality assurance, or compliance with strict industry standards, the PMP43 delivers reliable performance and long-term stability in the harshest hygienic environments.

1. Product Overview & Core Design

The E+H PMP43 is a compact, hygienic pressure transmitter designed for gauge, absolute, or differential pressure measurement (depending on configuration), with a focus on minimizing contamination risks and ensuring easy cleaning. Its sleek, crevice-free design eliminates dead zones where media can accumulate, a critical feature for sanitary processes that require frequent CIP (Clean-in-Place) and SIP (Sterilize-in-Place) cycles.
Constructed with high-quality 316L stainless steel (or optional Hastelloy for corrosive media), the transmitter’s flush diaphragm is polished to a Ra ≤ 0.8 μm surface finish, meeting the strictest hygienic standards. The diaphragm is hermetically sealed to prevent media penetration, ensuring product purity and protecting the internal measurement components from damage. Additionally, the PMP43 features a rugged housing with IP69K protection rating, making it resistant to high-pressure, high-temperature cleaning agents and suitable for use in wash-down environments.

2. Technical Specifications & Performance

The PMP43 stands out for its exceptional measurement accuracy and stability, ensuring precise pressure monitoring even in dynamic process conditions. Below are its key technical parameters:
  • Measurement Range: Gauge pressure: -1...0 bar to 0...400 bar; Absolute pressure: 0...1 bar to 0...400 bar (depending on model)
  • Accuracy: Up to ±0.075% of full scale (FS), ensuring reliable and consistent measurement results
  • Output Signals: 4–20 mA HART (version 7), IO-Link (IEC 61131-9), optional pulse output for flow calculation
  • Temperature Range: Process temperature: -40°C to +200°C; Ambient temperature: -40°C to +85°C (with optional cooling element for high-temperature applications)
  • Pressure Rating: Maximum working pressure: Up to 400 bar; Burst pressure: 1.5 × maximum working pressure
  • Hygienic Certifications: Compliant with 3A, EHEDG, FDA, and CE standards, ensuring compliance with global sanitary regulations
  • Process Connections: Tri-Clamp, Varivent, SMS, or custom connections, compatible with standard sanitary fittings
  • Power Supply: 12–30 V DC (for 4–20 mA HART); 20–30 V DC (for IO-Link)
With a response time of ≤ 10 ms (fast response option available), the PMP43 can quickly adapt to changes in process pressure, providing real-time data for process optimization and control. Its low temperature drift (≤ 0.01% FS/°C) ensures measurement accuracy even in fluctuating temperature environments, a common challenge in sanitary processing.

Pressure Transmitter FAQ

What is a pressure transmitter used for?

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.

How do I choose the right pressure transmitter?

Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.

What is the difference between gauge, absolute and differential pressure transmitters?

Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.

Can Xinyi Instrument provide customized pressure transmitters?

Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
