S5 Fuel and Water Sender - 0-190/240-30 Ohm is a Wema UK sender/sensor for accurate measurement input in compatible marine tank, engine or position systems. It is listed by TMP Global for customers who need the correct Wema part, finish and specification without guesswork.

• Sender/sensor component for feeding reliable tank, pressure, temperature or position data to a compatible display.
• Resistance options support common European and/or American sender ranges where selected.
• Available in multiple sender lengths so the part can be matched to tank depth.
• Fitting: SAE 5-hole bolt-down (40mm centre hole, 54mm PCD, M5 bolts).
• Material: 316 stainless steel.
• Output: 0-190Ω / 240-30Ω resistance (standard), or 0-5V / 0-10V / 4-20mA (custom).
• Lengths: 150–1600mm standard.
• Working voltage: 12V or 24V (draws power from gauge).

Choose the variant that matches the installation. Key variant choices include Length: 1000, 1100, 1200, 1300, 1400, 150, 1500, 1600, 175, 200, 2000, 225...; Output: American (240-30 ohms), European (0-190 ohms); Resolution: High resolution, Standard resolution.

Important compatibility notes: 0-190Ω — European specification 240-30Ω — American specification Sender and gauge must have the same resistance range — or the gauge will read backwards, or not at all; 240-30Ω — American specification Sender and gauge must have the same resistance range — or the gauge will read backwards, or not at all; 12V or 24V (draws power from gauge) Max carrying current: 1; 24V (draws power from gauge) Max carrying current: 1.

Check the selected variant's options, SKU and compatibility before ordering. If you are matching an existing sender, gauge or NMEA 2000 network, confirm the resistance range, voltage, fitting, cable length or connector type before installation.
