Pressure transmitters

Pressure Transmitters and Pressure Switches

Pressure transmitters and switches are essential components for monitoring and controlling pressure in automation and process systems.
They are designed to measure pressure in liquids, gases, or steam, converting the applied force into a precise electrical signal that can be used for control, monitoring, and safety applications.

These sensors are ideal for detecting both relative and absolute pressure, and are widely used in systems with rapidly changing or high-pressure environments, such as process pipelines, hydraulic systems, and closed vessels.

Key Features and Advantages

• High measurement accuracy for liquids, gases, and vapor pressure.

• Rugged construction with long-term stability and high resistance to mechanical stress.

• Protection against aggressive or high-temperature media through metallic or PTFE-coated diaphragms.

• Custom configurations available upon request, including pressure range, output type, and process connection.

• Durable operation in harsh industrial environments — temperature range from −40°C to +400°C and pressure up to 420 bar.

Pressure Switches and High-Pressure Transmitters

High-pressure switches and regulators are designed for demanding industrial conditions.
They often include components such as isolating diaphragms (CSB standard), which protect the sensor from:

• Corrosive media,

• Highly viscous materials,

• Elevated process temperatures.

These protective diaphragms also enable differential or level pressure measurement, ensuring safety and precision in operation.
Mounting is typically performed via flanges from DN40, with measuring cells starting from DN50.

Specialized Solutions

Our product range includes melt pressure transmitters featuring rigid stems and robust housings capable of withstanding high process temperatures — ideal for plastic and rubber extrusion lines.
The MPT pressure transducer series ensures accurate pressure measurement and stable operation, with variants available for both mercury-filled and oil-filled systems, depending on process requirements.

Professional Integration and Support

Sensors are usually supplied with sealed electrical connectors or integrated cables to ensure hermetic protection.
Connection type and configuration are selected according to the nature of the measured medium and maximum pressure parameters.
