The \u003cstrong\u003eEnerdrive 140mm 5-Bolt 240-33 Ohm Tank Level Sender\u003c\/strong\u003e is engineered to provide consistent, dependable readings for both fuel and water storage systems. Built to integrate seamlessly with compatible tank monitors and gauges, this unit eliminates the guesswork associated with fluid management in mobile and stationary setups.\u003c\/p\u003e\u003cp\u003eUnlike traditional swing-arm senders that require wide clearance and suffer from rapid mechanical wear in high-vibration environments, this sender utilises a vertical \u003cstrong\u003emagnetic reed switch mechanism\u003c\/strong\u003e. As the internal float moves vertically along the probe with the fluid level, it activates sealed internal switches to produce a steady, bounce-free resistance signal. This non-contact magnetic operation significantly reduces the risk of mechanical binding or premature failure caused by sloshing liquids during transit over corrugated roads or choppy waters.\u003c\/p\u003e\u003ch3\u003eEngineered for Harsh Environments\u003c\/h3\u003e\u003cp\u003eSubmerged components are constantly exposed to corrosive elements, moisture, and vapour. To combat degradation, the sender is constructed from \u003cstrong\u003esolid stainless steel\u003c\/strong\u003e, offering exceptional corrosion resistance in diesel, petrol, and fresh or grey water applications. The top mounting assembly features a sealed cable exit and carries an \u003cstrong\u003eIP67 ingress protection rating\u003c\/strong\u003e, safeguarding the internal electronics and wiring connections against dust and temporary water immersion.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic Reed Switch Technology:\u003c\/strong\u003e Delivers a steady, reliable signal without the mechanical wear or clearance issues of traditional swing-arm floats.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolid Stainless Steel Build:\u003c\/strong\u003e Provides superior durability and corrosion resistance for long-term submersion in fuel or liquid tanks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e240-33 Ohm Output Signal:\u003c\/strong\u003e Matches standard American resistance-system gauges, reading 240 Ohms when empty and 33 Ohms at full capacity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 Waterproof Rating:\u003c\/strong\u003e Fully sealed top housing and cable exit protect against moisture, dust, and harsh under-body or marine bilge conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard 5-Bolt Flange:\u003c\/strong\u003e Ensures a secure, leak-resistant mechanical seal on compatible tank apertures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Focused Design:\u003c\/strong\u003e Built with anti-explosion and corrosion-resistant properties suitable for volatile fuel environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eVersatile Applications and System Compatibility\u003c\/h3\u003e\u003cp\u003eWith a compact \u003cstrong\u003e140mm probe length\u003c\/strong\u003e, this level sender is specifically suited for shallow tanks, custom sub-tanks, marine day tanks, and under-body caravan water storage where vertical depth is restricted. It connects directly to standalone gauges or integrated battery and tank management systems—such as the Enerdrive ePRO Plus or Simarine monitoring platforms—that accept a 240-33 Ohm resistance input.\u003c\/p\u003e\u003cp\u003eBefore installation, verify that your tank has sufficient clearance for the 140mm probe depth and utilizes a matching 5-bolt mounting pattern. Confirming that your display gauge operates on the 240-33 Ohm standard (rather than the European 0-190 Ohm system) ensures accurate plug-and-play calibration.\u003c\/p\u003e\u003ch3\u003eUpgrade Your Tank Monitoring Setup\u003c\/h3\u003e\u003cp\u003eEquip your caravan, 4WD, or marine vessel with dependable fluid tracking.
