These pressure sender units suit VDO electrical oil, fuel or air pressure (boost) gauges. Some senders are earthed. Other senders are not earthed, i.e. earth is supplied by a separate connection. Pressure senders can be fitted with an additional warning contact in order to indicate when the pressure limit has been reached, as well as carrying out continuous measurement.

• Designed to work with VDO gauges

• Common ground connection is made through the unit threads

T pieces and adaptors to suit various applications are available separately.
