VDO Pressure Sender 150 PSI Floating Ground - 1/8-27 NPT

The VDO Pressure Sender 150 PSI Floating Ground with 1/8-27 NPT connection is a precision marine instrument that monitors fuel, oil, water, or other fluid pressures in applications where floating ground operation is required. Built to VDO's exacting standards, this pressure sender delivers reliable readings across a 150 PSI / 10 bar maximum range, making it ideal for recreational and commercial marine environments where accuracy and durability are non-negotiable.

Operating on a 6–24V DC power supply, this sender uses a 10–180 Ohm output range to communicate pressure data to compatible gauge systems, eliminating the need for a dedicated ground wire on the sending unit itself—a key advantage in complex marine electrical systems where ground isolation prevents interference and noise. The knurled nut connection ensures secure, hand-tight installation into 1/8-27 NPTF threaded ports without requiring special tools. At just 0.3 lbs, the compact form factor minimizes installation complexity on cramped engine blocks or fuel systems while maintaining the robust construction expected from VDO's industrial-proven sensor design.

This sender suits retrofit installations and new-build systems where engine compartment salt-air exposure demands corrosion-resistant materials and proven reliability. Boaters running fuel-injection diagnostics, monitoring hydraulic systems for trim tabs or bow thrusters, or tracking transmission fluid pressure will benefit from the floating ground configuration's noise immunity and clean signal transmission to marine-grade gauge clusters. The VDO Pressure Sender 150 PSI is sold as an individual unit, allowing straightforward replacement or addition to existing monitoring systems without unnecessary bundling.
