FmtS Transducer

Overview

The FmtS is a robust high precision force transducer. The FmtS is manufactured with an “epoxy bonding” process.

Typical applications for the FmtS range from computer labs, industrial equipment, remotely piloted vehicles, payload control, and military equipment such as computer-based training systems. The rugged design means that they will provide reliable service for extended periods, backed by a two-year warranty.

The FmtS produces an output based on the force applied in either the lateral or longitudinal axis.

The FmtS is also available with a pushbutton feature making it ideal for cursor control and target designation. These are available in the epoxy version with p/n FmtS-PB-xxx

Technical

Key Features

Mechanical

The external casing is stainless steel. The output shaft is a 2.2mm hardened stainless steel onto which a variety of knobs can be mounted.

Electrical

The force applied to the transducer is measured by silicon strain gauges mounted as a bridge. It provides output voltage through a signal conditioning amplifier. The centering repeatability error is less than 0.5%.

Reliability

With no moving parts, the life of the mechanical system has no limit when mounted and used correctly.

Knobs

The standard is a hat-style anodized aluminum knob. See the options tab for details.

Warranty

The FmtS transducers carry a 2-year warranty.
