RE 101 – One-channel Position Transmitter

The RE 101 transmitter is a one-channel position transmitter designed to work with contactless proximity probes. It measures the relative position of an object and automatically compensates for temperature variations in the probe, ensuring highly reliable and accurate displacement measurements in industrial applications.

Reliable Position Measurement with Proximity Probe Integration

The RE 101 is optimized for static displacement measurement and integrates seamlessly with proximity probe types RE 022 and RE 030. Its measuring range corresponds to a 4 to 20 mA output, while additional voltage output of 0.5 to 4.5 V is available. Built with a rugged aluminum housing, IP67 protection, and multiple analog outputs, the RE 101 provides robust performance in demanding industrial environments.

For added flexibility, the RE 101 offers adjustable offset, sensitivity, and linearity, allowing fine-tuning to specific materials and installation conditions. Its integrated fault detection includes short-circuit and cable break monitoring, with visual red LED indicators and error signaling through the analog output.
