摘要：Cerabar PMC21: Oil-Free Ceramic Sensor The PMC21 uses a capacitive, oil-free ceramic sensor for absolute or gauge pressure measurement in gases and liquids. It is an option to evaluate where ceramic diaphragm compatibility and compact installation are relevant. Cerabar PMP21: Metallic Measuring Diaphragm The PMP21 uses a piezoresistive sensor with a metallic measuring diaphragm. Its sensor range options extend to higher pressures than those of the featured PMC21 and PMP23 models.

Endress+Hauser Cerabar PMC21, PMP21 and PMP23: Compact Pressure

Transmitters for Different Process Requirements

Pressure transmitter selection involves more than choosing a measuring range. Sensor technology, process connections and material compatibility also affect whether an instrument matches the application.

HONGKONG XIEYUAN TECH CO., LIMITED introduces three compact Endress+Hauser Cerabar models—PMC21, PMP21 and PMP23—to help customers distinguish between ceramic sensor, metallic sensor and hygienic pressure measurement options.

Featured Models

Cerabar PMC21: Oil-Free Ceramic Sensor
The PMC21 uses a capacitive, oil-free ceramic sensor for absolute or gauge pressure measurement in gases and liquids. It is an option to evaluate where ceramic diaphragm compatibility and compact installation are relevant.

Cerabar PMP21: Metallic Measuring Diaphragm
The PMP21 uses a piezoresistive sensor with a metallic measuring diaphragm. Its sensor range options extend to higher pressures than those of the featured PMC21 and PMP23 models.

Cerabar PMP23: Hygienic Process Connections
The PMP23 features a flush-mounted 316L metallic diaphragm and hygienic process connection options. It is designed for applications where cleanability and hygienic installation requirements influence instrument selection.

Model Comparison

Model	Sensor technology	Manufacturer-listed sensor range options*	Main selection focus
PMC21	Capacitive ceramic	100 mbar to 40 bar	Oil-free ceramic sensor
PMP21	Piezoresistive, metallic diaphragm	400 mbar to 400 bar	Metallic sensor and higher-pressure options
PMP23	Piezoresistive, flush-mounted metallic diaphragm	400 mbar to 40 bar	Hygienic connections and cleanability

Check the Complete Configuration

Before ordering, confirm whether gauge or absolute pressure is required. Also check the calibrated range, medium, process temperature, connection thread or clamp standard, electrical connection and output signal.

For hygienic applications, specify the required connection, surface finish and documentation. Available approvals must be checked against the exact order

Quick Q&A

Q1: Does the PMP21 automatically replace the PMC21?
A replacement requires checking sensor material compatibility, measuring range, connections, output and operating conditions.

Q2: Why consider the PMP23 for hygienic installations?
Its flush-mounted metallic diaphragm and hygienic connection options address installation requirements where cleanability is a priority.
