The Drakefield SensorMaster DRA08 is a handheld EBS / ABS sensor and exciter ring tester, for use on trucks, trailers, and buses.

Overview of the Drakefield SensorMaster DRA08

Conventional wisdom has it that problems with EBS / ABS systems fitted to trucks, trailers and buses, are best diagnosed via the vehicle's Electronic Control Unit (also known as the ECU). However, since 80% of all EBS / ABS problems are sensor related*, by connecting to the sensor socket on each wheel (which is what the SensorMaster DRA08 does - see Fig. 1 below) rather than the ECU, you are, in effect, taking the quickest and most direct route, by going straight to the heart of the problem.

Lightweight and portable, the Drakefield SensorMaster DRA08 comes supplied with two 1.6m high quality cables, a sturdy carry case, short introductory printed manual, and a single 9V battery - everything, in fact, needed to use it straight out of the box.

Designed with ease of use in mind, the SensorMaster DRA08 takes minutes to set-up, and, once connected, undertakes a complete test cycle of the six most common causes of EBS / ABS faults, at the touch of a button, in just 15 seconds - a fraction of the time it would take to perform the same tests manually.

A list of the tests undertaken by the Drakefield SensorMaster DRA08, along with other important features and benefits of the unit, can be found in the table below.

Product feature

Customer benefit


The SensorMaster DRA08 Fits comfortably in the hand, and is easy to operate in cramped or awkward situations, for example, underneath a vehicle.


The SensorMaster DRA08 is ideal for mobile diagnostic use. It runs off a standard 9V battery, so requires no mains leads, and is robust enough to use in adverse weather conditions.

Easy to use

All the instructions necessary to use the SensorMaster DRA08 are printed on the face of the unit. A short introductory printed manual is also supplied. You can be up and running in literally a matter of minutes. Faults are indicated by easy to follow LED displays, and the unit also indicates when the battery needs replacing.


The SensorMaster DRA08 can complete a test cycle of the six most common causes of sensor related faults, at the touch of a button, in just 15 seconds - a fraction of the time it would take to perform the same tests manually.


However, speed is nothing without accuracy, and the SensorMaster DRA08 delivers precise, accurate results that are easy to interpret.


The SensorMaster DRA08 has been designed and tested for professional use. It is manufactured from high quality components, has a wipe clean surface, and comes supplied with it’s own protective carry case, two 1.6m high quality cables, and 1 year parts and labour (return to base) Warranty.


The SensorMaster DRA08 is compatible with 90% of applications as standard. It works with any EBS / ABS system manufactured by either Knorr-Bremse, Haldex or Wabco, fitted to any type of commercial vehicle, whether it be a truck, trailer, bus, or coach.

Cost effective

The SensorMaster DRA08 is one investment decision that isn’t difficult to justify, given its speed, ease of use, accuracy, and price.


The SensorMaster DRA08 tests for the six main causes of sensor related faults on EBS / ABS systems:

  • Correct Ohms resistance
  • Open circuit
  • Short circuit
  • Pole ring tooth damage
  • Pole ring misalignment
  • Sensor gap measurement
