The S5 sender from Wema is an innovative solution for monitoring the level of fuel and/or water tanks in boats, trucks, coaches, caravans and recreational vehicles.
Mounts via a five-hole pattern flange which can be simply fitted into the top of a matching tank. Rated 240-30 Ohm. You must match the same Ohms rated senders with gauges.
- Mounting type: 5-hole SAE flange
- 240 - 30 Ohm resistance senders
- Length is measured from the underside of the flange to the base of the shaft
- Longer senders available on request
- Suitable replacement for UFW and SUF fuel level sensors
- Medium - diesel, petrol, potable and grey water (not black water)
- Operating voltage - 12/24 VDC
- Material AISI 316 stainless steel
- Operating temperature - -40° to +85°C
- Termination - two flying leads (tinned) 290mm long (sheathed)
Non corrosive materials in order to withstand the rigors of their operating environment. We take an uncompromising stance on quality; therefore, our level sensors are constructed to meet all applicable ISO, CE, NMMA, ABYC and USCG standards.
Troubleshooting:
To test operation, unscrew the fuel sender, connect two wires to a multimeter, set to resistance and move the float up and down by hand.
A-Sensor: With the float at the bottom it should read 240 ohm and at the top 30 ohm.
