TWW 101 M1 – One-channel Position Transmitter

The TWW 101 M1 transmitter is a one-channel position transmitter designed for static displacement measurement using eddy current proximity probes. It enables contactless monitoring of the relative position of a measuring object and provides reliable performance in industrial environments.

Flexible and Accurate Position Transmitter

The TWW 101 M1 is compatible with proximity probe types WW 007, WW 009, and WW 030, supporting measuring ranges between 2 mm and 12 mm. Two measuring ranges can be selected via a DIP switch, with all settings documented in the test protocol and housing. The transmitter provides dual analog current outputs (4–20 mA) and offers optional voltage output, enabling versatile integration into monitoring systems.

Internal fault detection ensures maximum reliability by generating alarms when objects are outside the measurement range, or when short circuits or cable interruptions occur. Additional fine-tuning of offset and sensitivity via potentiometers allows the TWW 101 M1 to be adapted to different materials and installation conditions.
