Rochester Sensors TLL155 1/2 in. NPT Capacitive Fuel Level Sensor w/ C/K16 & S/K155 Kit - 500mm

The Rochester Sensors TLL155 Capacitive Fuel Level Sensor is a precision-engineered solution for monitoring fuel levels in diesel and kerosene tanks. Designed for industrial and automotive applications, this sensor offers flexible output options including resistive, voltage, and current signals, making it compatible with standard fuel gauges and PLC systems.

The included C/K16 Mating Connector Kit and S/K155 Shortening & Calibration Kit enhance installation and customization, allowing users to cut the 500mm stainless steel probe to length and calibrate it magnetically. Built with durable materials and rated IP67 for ingress protection, the TLL155 ensures reliable performance in harsh environments, withstanding vibration, shock, and temperature extremes.

Features

• Flexible Output Compatibility: Supports resistive (240–33Ω), voltage (0–5V/0–10V), and current (1–20mA/4–20mA) outputs for integration with gauges and PLCs.
• Customizable Installation: Includes S/K155 kit for probe shortening and calibration, and C/K16 kit for secure electrical connection.
• Rugged Construction: Made with 316 stainless steel and high-grade polymers for durability in demanding environments.
• Integrated Alarm Function: Alarm output activates at 12% of active length, providing early warning for low fuel levels.
• Environmental Protection: IP67-rated housing with resistance to shock, vibration, and wide temperature ranges.
