E&H PMC11 pressure transmitter

E&H PMC11 pressure transmitter

1. Product Overview

The Cerabar PMC11 is a compact pressure transmitter designed for cost-conscious applications that do not compromise on measurement quality. At the heart of this device lies a capacitive ceramic measuring cell that operates without oil filling, eliminating common failure points associated with traditional pressure sensors-7.

Manufactured with high-quality materials including 316L stainless steel and 99.9% Al₂O₃ ceramic, the PMC11 pressure transmitter withstands challenging conditions across process industry environments. Whether measuring gases, vapors, liquids, or dust, this device provides consistent, repeatable pressure readings with minimal maintenance requirements-6.

The transmitter’s compact construction simplifies installation and setup within existing plants. Users can customize measuring ranges directly at the factory, reducing on-site configuration time and minimizing potential errors during commissioning-6.

2. Key Features and Technology

2.1 Oil-Free Ceramic Sensor

Unlike conventional pressure transmitters that rely on oil-filled systems, the PMC11 employs a capacitive, oil-free ceramic membrane known as Ceraphire. This design offers distinct advantages:

Zero oil migration risk – eliminates potential process contamination

High abrasion resistance – withstands particulate-laden media

Vacuum-proof construction – maintains integrity under negative pressure

Exceptional long-term stability – 0.2% of URL per year-7

2.3 Environmental Specifications

2.4 Electrical and Communication

The transmitter supports two analog output configurations:

4‑20 mA output: Supply voltage 10–30 VDC

0‑10 V output: Supply voltage 12–30 VDC-7

Electrical connections include valve plugs conforming to ISO4400 M16 standard, as well as M12 connector options for more compact installations.

6. Installation and Operational Considerations

6.1 Mechanical Installation

The compact form factor of the PMC11 simplifies integration into tight spaces. The process connection mounts directly to standard threaded fittings. Orientation of the housing can be adjusted to facilitate cable routing and display readability.

For optimal performance:

Install with the diaphragm oriented downward for liquid applications to prevent air entrapment

For gas measurements, position the transmitter above the tapping point

Protect the ceramic diaphragm from mechanical impact during installation

6.2 Electrical Connection

The ISO4400 M16 valve plug provides secure, weather-resistant connection. When wiring:

4–20 mA configuration: Connect positive to pin 1, negative to pin 2

0–10 V configuration: Refer to specific wiring diagram in operating instructions

Use shielded cable for installations in electrically noisy environments

Ensure proper grounding to prevent EMC interference

6.3 Storage and Transport

Store the device in its original packaging under clean, dry conditions. The storage temperature range of –40 to +85 °C accommodates most warehouse environments. Protect the device from shocks during transport per EN 837-2 requirements-37.
