HOW TO TEST & ORDER A REPLACEMENT SENDER
SENDER IDENTIFICATION CHART

DESCRIPTION

Robustly made from 316 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.

We now offer high-resolution senders from 150mm to 400mm.  These 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.

They have proved very reliable and this technology is used by all major European truck and bus manufacturers and on many off road vehicles.

Senders are available with either a 1 ¼” BSP male thread (S3) or a 5 hole flange (S5) and are made in a series of lengths from 150mm - 1600mm.

Longer senders and bespoke options are also available including different outputs; 0-5v, 0-10v, 4-20ma... Please get in touch to find out more. 

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.

 

 

WIRING

Simply connect one wire to earth and the other wire to the sensor cable on the gauge.

 

TORQUE SETTINGS

Use these torque settings when screwing the S3 sender (with o'rings mounted) into a flange:

Steel Flange:  9 ± 1 Nm
Nylon Flange:  7 ± 1 Nm

Replacement water sender

Telephoned Wema themselves to check I was ordering correct sender, as new one very slightly shorter than old one. Instant excellent service from the gentleman we spoke to, very helpful and knowledgeable. Could then order online in certainty of the correct part. Arrived in a couple of days, easily fitted in minutes when back on boat. Works perfectly.
