Best Endress+Hauser Cerabar PMP71B - pressure transmitter Supplier, Products

Overview

The Endress+Hauser Cerabar (new generation) is a robust pressure transmitter featuring high accuracy—up to 0.05% as standard and up to 0.025% for platinum configurations—with a pressure measuring range of 400 mbar to 700 bar (1.5 psi to 10,500 psi), matching its measuring cell capacity of 400 mbar to 700 bar (6 psi to 10,500 psi).

It adapts to diverse process conditions: standard process temperatures range from -40°C to +125°C (-40°F to +257°F), and with a diaphragm seal, this extends to -40°C to +400°C (-40°F to +752°F); its main wetted parts and process membrane use corrosion-resistant materials including 316L, Alloy C, Tantal, Monel, PTFE, and Gold for compatibility with varied media.

Designed for user convenience and reliability, it supports secure wireless control via the SmartBlue App on mobile devices, with intuitive software wizards guiding setup, proof tests, and verification; it also integrates Heartbeat Technology for in-process device health verification and anomaly monitoring (e.g., changes in loop characteristics).

Process Diagnostics

Verify device health without process interruption. Clear status indication shifts from green to red on diagnostic alerts.

Safety Commissioning

Reduced systematic failures via error-free SIL commissioning and instrument-guided proof testing.

Wireless Oversight

Supports secure wireless control and status overview directly in the process area.

Frequently Asked Questions

What is the accuracy profile of the Cerabar PMP71B transmitter?

The Cerabar pressure transmitter offers high measurement accuracy up to 0.05% as a standard setup, and goes up to 0.025% for high-precision platinum configurations.

Can this transmitter withstand high process temperatures?

Yes, standard process setups handle temperatures from -40°C to +125°C (-40°F to +257°F). When fitted with a diaphragm seal, its capability extends significantly to handle temperatures between -40°C and +400°C (-40°F to +752°F).

What materials are used in the process membrane to resist corrosion?

To match diverse process media, the wetted parts and process membranes are manufactured using robust, corrosion-resistant materials such as 316L stainless steel, Alloy C, Tantalum, Monel, PTFE, and Gold.

How does Heartbeat Technology benefit operations?

Heartbeat Technology allows you to perform in-process diagnostics and verify device health status without stopping your processes. Diagnostics are visually indicated by a direct color shift from green to red on the LED display.

Does the Cerabar support wireless management?

Yes. The transmitter supports secure wireless oversight and operation in the field using Bluetooth® connectivity via the SmartBlue mobile application, featuring guided wizards for commissioning and validation.
