TGSS

Product catalog summary

Application:

Non-contacting signal input for accurate vehicle speed measurement regardless of wheel size or slippage.
Essential for systems requiring precise speed data such as anti-slip and traction control.
Compatible with a range of instrumentation supplied by RDS Technology.

Principle of Operation:

The TGSS operates on the Doppler shift principle, using a low power K band microwave beam. The beam is transmitted to the ground and the reflected signal's frequency shift is proportional to the vehicle's forward speed.

Kit Components:

Sensor
Mounting Plate
Extension Cable
Fixings and fasteners

Catalog excerpts

TGSS (MkIII) True Ground Speed Sensor Measurement of true vehicle speed regardless of wheel size or slippage Application: • Non-contacting signal input for true measurement of vehicle speed regardless of wheel size or wheel slippage. • Used where accurate speed measurement is required. • Essential for anti-slip systems, traction control etc. • RDS Technology also supplies a wide range of instrumentation to be used with the TGSS. Principle of operation: The TGSS uses the well known principle of Doppler shift. A low power K band microwave beam is transmitted at, and reflected from, the ground. The reflected signal differs from the transmitted one by the doppler shift. The difference in frequency is directly proportional to the forward speed. The kit includes Sensor, Mounting Plate, Extension Cable, Fixings and faste
