Introduction

The Michigan Scientific Clamping Battery Telemetry (CBT) is a wireless, battery powered, signal transmitter for strain gauges that easily mounts to shafts with a minimum diameter of 25 mm, making it ideal for shaft mounting and very versatile. The Michigan Scientific Telemetry provides reliable signal transmission without interference or signal spikes.

Installation

The CBT can conveniently be strapped to any shaft with load rated plastic zip ties, steel banding, or hose clamps. The CBT provides excitation and signal conditioning to the strain gauges, then digitally transmits the signals via RF in the 2.4 GHz broadcast frequency range.

For higher speed shafts when shaft balancing is required a counter weight can be purchased and should be mounted 180 degrees opposite the CBT. The CBT is a small rugged housing and is designed for hostile environments.
