DESCRIPTION AND OPERATION (Continued)

Aftermarket sensors

Aftermarket sensors are unpainted and are packed in

a cardboard package that exposes the aluminium

membrane for spray painting, once painted remove

the cardboard surround. The membrane has a yellow

chromate finish so that the finish paint can adhere

easily. This coating must be clean and dry before

paint application. Alcohol may be applied with a clean

lint free cloth, ensure the edge of the membrane is

also cleaned. Ultrasonic cleaning must not be used.

Scratched or damaged membranes are

unserviceable; the complete sensor must be replaced.
Aftermarket RPA kits comprising: Sensors, decoupling

rings, housings, retaining springs, contour rings, ecu

and harnesses.

Painting sensors

Paint must be applied to a maximum thickness of

120µm with no runs. A waiting time of 24 hours is

recommended after painting and drying to ensure a

durable finish.
The drying temperature must not exceed 105

°C with a

maximum drying time of 30 minutes, exceeding this

will damage / render inoperable the sensor. Sensors

are normally housed in a paint box that exposes only

the areas to be painted.

Storage of unpainted sensors

Storage temperature -57 to 100

°

Relative humidity 80%
Storage duration 6 Months
Longer storage times before painting will degrade the

chromate surface.
Operate a first in, first out parts supply.

ESD Protection

All work that is carried where it is possible to touch

the connector pins, proper ESD protection procedures

must be followed. Eg a grounded wrist strap and an

anti static mat.
