Wema Fuel & Water Tank Sender S5 (5 bolt) 17.5cm

Robustly made from 316 stainless steel and fitted as original equipment for over 30 years by all the major British and European boat builders, Wema Fuel and Water Tank 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 Wema S5 Tank 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.

These Tank Senders are the same as the standard-resolution in every way except we have placed the switches at ~every 10mm instead of ~every 20mm giving you more accuracy and clarity in the shallowest of tanks.

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.
