KUS S5U-19 Water Level Sensor – 1.5" NPT (19" Probe)

About the Product The KUS S5U-19 is a 19" probe, 1.5" NPT liquid level sender for water, fuel, or diesel tanks. It outputs the American Standard 240-33 ohm curve, which is what most US-market water and fuel gauges read, so it pairs with any 240-33Ω gauge without a signal converter. Inside, a magnetic float slides along a chain of reed switches. The float is the only moving part, so there is no wiper arm to wear out or corrode. **CURRENTLY ON A 3-4 WEEK LEAD TIME** Features Specifications Probe length: 19" Mounting: 1.5" NPT male thread, hex head Output: American Standard, 240Ω empty to 33Ω full Sensing: reed switch chain with magnetic float Resolution: 21mm Body: SUS 316 stainless steel Float: NBR Leads: PVC jacketed, pink (ground) and black (signal) Protection rating: IP65 Operating temp: -40°F to +185°F Power: 12V or 24V systems, 125mW Manufacturer part number: KUS 154019 Materials & Certifications Rated for water, gasoline, diesel, and hydraulic oil 316 stainless steel body and NBR float, both corrosion resistant IP65 sealed housing Genuine KUS Americas part What's Included (1) KUS S5U-19 sending unit Installation & Wiring Threads into any 1.5" NPT tank port. Use a thread sealant rated for what is in the tank. Turn it until the leads point toward your wire run, then snug it down. Do not overtighten. Leave at least 1" between the tank bottom and the float collar (0.5" on stainless or aluminum tanks). Measure from the inside bottom of the tank to the top of the port before picking a probe length. Pink to ground, black to the sender terminal on your gauge. Two wires, no power feed. You need a gauge on the 240-33Ω curve to read it. Most van builds do not have one until you add it, so check what your panel reads before ordering.
