Wheel Pulse Transducer Type CWPTA 3. Product Overview 3.1 General Description WPT sensors are universally adaptable sensors for the acquisition of vehicle wheel speed. The sensors deliver 1 000 pulses per rotation (standard, other values on request). WPT sensors are ultra-compact and extremely light in weight. -
Page 9: Application
Product Overview 3.3 Application WPT sensors can be applied for the following measure- ments: Wheel slip measurement Acceleration and braking tests ABS testing Measurement of difference between wheel speeds when using more than one wheel pulse transducer (e.g. with all-terrain vehicles) 3.4 Accessories Included Accessories Type/Art. -

Wheel Pulse Transducer Type CWPTA 5. Set-up and Connection 5.1 Mounting – General Notes The wheel pulse transducer mounts to the wheel lug nuts via adjustable mounting collets. The torsional protection rod (which maintains rotation around the wheel axis) is affixed to the vehicle body with suction holders. -

Page 16: Monting Instructions
Wheel Pulse Transducer Type CWPTA 5.3 Mounting Instructions Select the parts depicted below. Fig. 4: Mounting collets (1), retainer screws with washers (2), mounting disk (3), hexagon nut driver (4) Remove hubcap or any covering over wheel nuts and clean dirt/debris from wheel nuts. - Page 17 Set-up and Connection Align the mounting disk with the collets and affix it with retainer bolts and washers. Do not fully tighten the bolts at this step! Each mounting slot on the disk is marked to ensure proper alignment with 3-, 4-, and 5-lug configurations. The lobe of the washers must show towards the collets.
- Page 18 Wheel Pulse Transducer Type CWPTA Fig. 7: Centering the mounting disk Continue to hold the centering star tightly against the mounting washers, then tighten the mounting bolts in a cross pattern. The deviation of concentricity should be within 0,2 mm (see page 23, "Signal errors due to incorrect mounting").
- Page 19 Set-up and Connection Select the parts shown below. Fig. 9: WPT Sensor with mounting plate (1), mounting bolt (2), torsion mounting assembly (3), suction mount (4), extension rod (5) If the transducer mounting plate is not already mounted to the transducer, slide the plate onto the back of the transducer as shown below and secure it by tightening the set screw.
- Page 20 Wheel Pulse Transducer Type CWPTA Slide the transducer mounting bolt through the hole at the center of the transducer, then thread the bolt into the hole at the center of the mounting hub. Tighten the bolt securely using the knob.
- Page 21 Set-up and Connection The slot of the spacer must be directed towards the sensor. Axial load exceeding 20 N / radial load exceeding 40 N will damage the sensor! Measure or – if applicable - visually estimate the distance from the top of the transducer mounting clamp to an area of the vehicle body onto which the suction holders can be attached.
- Page 22 Wheel Pulse Transducer Type CWPTA Press the suction holders firmly against the vehicle body and latch the suction holder lock handles (latched position is approximately parallel to vehicle body surface). When the suction holders produce an effective vacuum, you will feel a distinct resistance.
- Page 23 Set-up and Connection Wind the signal cable loosely around the torsion rod and secure with a cable tie. Be sure to leave enough slack in the cable to allow for suspension travel, but use caution to assure that the cable is not wound too loosely around the torsion bar.

Page 24: Connecting The Sensor
5.4 Connecting the Sensor Finally, connect the signal cable to data acquisition. When using other than Kistler data acquisition systems, make sure that the polarity of the sensor supply is correct and the data acquisition supplies the sensor-specific current and signal conditions. -
