Collection of automotive sensors including level senders for original equipment applications.

Senders - Level, Temp, Pressure, NMEA2000

Robustly made from stainless steel and fitted as original equipment for over 30 years by all the major British and European boat builders, our senders still work on the simple principle of twin magnets in the float tripping a series of reed switches securely housed, and doubly insulated inside the stainless tube.

Over the years senders have been improved with advances in reed switch technology, allowing us to fit far more switches inside the senders, giving the better resolution required by modern digital displays. They have proved very reliable and the same technology has also been used by all major European truck and bus manufacturers and are used on many off road vehicles.

Level senders are available with either a 5 hole flange (S5) or 1 ¼” BSP male thread (S3) and are made in a series of lengths from 150mm -1600mm, although longer senders and bespoke options are available. There are two standard resistances, 0-190 ohm, used mainly in European gauges and 240-30 ohm used by American gauge manufacturers. Senders and gauges must have the same resistance range.

Other specialist level senders with fuel suction and return also available.
