GST Series
Gear Lever Load Cell
Features
The GST Series of gear lever load cells are designed for the detection and measurement of tension/compression
forces in gear shift application. Suitable for demanding motorsport and on-vehicle automotive testing.
 Sequential or ‘H’
Pattern Gearboxes
Construction is aluminum with a built-in amplifier which allows for a very simple installation, only 3 wires are
needed for connection. Mechanical mounting is via M10 female threads, but custom designs are also possible.
 ±35lbsf to ±220lbsf
The output signal is proportional to the amount of force and is a linear 0.5 to 4.5V and can be connected to
most common ECU’s. Configuration for either Sequential or ‘H’ Pattern gearboxes. The load cell can be supplied
 5V or 8-16V Supply
with or without a cover.
 Low
 Pressure
Built-in Amplifier
The typical application is for use as: Flat Shift / Quick shifter / Torque Cut / Ignition Cut / Clutch free Gearshift
 Barometric
 ±0.5% Accuracy
on race vehicles.
Applications
The load cells are generally installed on top of the gear change lever and will detect the level of force applied by
the driver to change gear.
 Boost
