The S5-170HL is a rugged, fully sealed float-type level sensor engineered for continuous liquid-level measurement in diesel fuel tanks of on- and off-highway vehicles.
Designed around the industry-standard SAE 5-hole mounting pattern, the unit installs in minutes on existing flanges without tank modification.
Its thick-film resistive output (0–190 Ω typical) is compatible with most OEM and aftermarket dash gauges, engine controllers, telematics nodes and SCR systems.
Key Features
• SAE 5-hole flange – drop-in replacement for common truck, bus and agricultural tanks
• 304 or 316 stainless-steel stem & Buna-N float for long-term diesel compatibility (-40 °C to +125 °C)
• IP67 ingress protection—survives high-pressure wash, mud, dust and vibration
• ±2 mm repeatability and 0.5 % linearity over full span; field-calibratable arm length 170 mm (custom on request)
• RoHS compliant, CE-marked
Typical Applications
• Commercial trucks & tractor fuel tanks
• Diesel generators and construction equipment
• Agricultural & forestry machinery
• Marine auxiliary engines
