Cerabar PMC71B Pressure Transmitter
Part number PMC71B
Digital pressure transmitter with Ceraphire ceramic measuring cell, 4–20 mA HART, Bluetooth commissioning, Heartbeat Technology, SIL2/3.
- CE
- ATEX
- IECEx
- SIL2
- RoHS
Overview
The Cerabar PMC71B is the ceramic-cell member of Endress+Hauser's current Cerabar generation, for gauge and absolute pressure from 100 mbar to 40 bar. The gas-tight Ceraphire ceramic diaphragm tolerates abrasive and corrosive media and vacuum, and survives overload far better than metal diaphragms — which is why it is the default choice for water, chemicals and food processes. Commissioning is done from a phone via Bluetooth and the SmartBlue app; Heartbeat Technology verifies the device without removing it from the process. PMC71B is an ordering family: the complete code specifies range, process connection, output and approvals. We configure it with you before quoting.
Key features
- Ceraphire ceramic measuring cell: overload-resistant, vacuum-proof, abrasion-resistant
- Reference accuracy up to ±0.05 % (Platinum version), long-term stability ±0.05 %/year
- 4–20 mA HART; optional Bluetooth, PROFINET with Ethernet-APL or IO-Link
- Heartbeat Technology: diagnostics, verification and monitoring
- SIL2 (SIL3 in homogeneous redundancy) per IEC 61508; ATEX, IECEx, CSA, NEPSI approvals
Typical applications
- Process pressure in water, chemical and food plants
- Hydrostatic level in open and closed tanks
- Pump and filter monitoring
- Safety instrumented systems

Frequently asked questions
Why choose the ceramic PMC71B over the metal-diaphragm PMP71B?
Ceramic handles abrasive slurries, vacuum and chlorides better and is vacuum-proof. Choose PMP71B when pressure exceeds 40 bar, when a diaphragm seal is needed for high temperature, or when hydrogen permeation is a concern.
Is the PMC71B available from stock, and what is the lead time?
Availability of the Cerabar PMC71B Pressure Transmitter changes with manufacturer production and distributor stock, so we confirm it per request rather than publishing a number that may be out of date. Send the part number and quantity through the quote form and you will receive stock position and lead time within one business day.
Is the PMC71B genuine, and what documentation comes with it?
We supply only genuine Endress+Hauser products sourced from the manufacturer or authorized distribution channels. Each delivery includes the commercial invoice and packing list; a Certificate of Conformance, declaration of conformity and country-of-origin statement are provided on request, and the manufacturer's warranty applies.
Can you ship the PMC71B outside Vietnam?
Yes. We quote EXW Hai Phong, FCA/FOB, CIF or DAP and prepare the export documentation. Buyers in Japan, ASEAN, Europe and North America regularly consolidate multi-brand orders with us into one shipment.
What if the PMC71B is the wrong variant for my application?
Tell us the application in the notes field. Our engineers check the ordering code against your supply voltage, I/O, communication and environmental requirements and propose the correct variant or a successor part before quoting — at no charge.
