The Products of Trafag – Sensor and Controls

Pressure Transmitter

Trafag pressure transmitters are used for electronically measuring and evaluating pressure. Over the decades they have proven themselves in a multitude of demanding applications in harsh environments.

They are available in many different designs to suit pressure and electrical connections, measuring procedures, electrical output signals, and certifications (CE, EX, rail, and ship). Superior technology and precise manufacturing ensure that the transmitters work perfectly. This is especially important in applications where high requirements are placed on long-term stability, vibration resistance, electromagnetic compatibility, shock resistance, or temperature insensitivity.
