17 Juin Rochester Sensors Introduces T/LL470: A Rugged, High-Precision Liquid Level Sensor for Extreme Temperature Applications
Warwick, UK [June 2025] – Rochester Sensors UK is pleased to announce the launch of the T/LL470 Extended Temperature Range Liquid Level Sensor, and advanced and rugged solution for continuous liquid level monitoring in extreme operating conditions.
Engineered for accuracy, durability and versatility, the T/LL470 features continuous level monitoring via an advanced capacitance sensing system, delivering a configurable voltage output ranging from 0 to 10 VDC. Compact and robust, this sensor is ideal for use in shallow tanks and sumps containing engine oil, coolant, fuel or hydraulic fluid – especially in extreme temperature conditions.
« T/LL470 meets a critical need for reliable sensing in high-temperature and high-vibration environments, » said Steve Lowe, Product Manager at Rochester Sensors. « Our customers in sectors such as construction, agriculture, and industrial equipment can monitor fluid levels with greater accuracy and confidence ».
Key Features:
- Operating Temperature Range: -40°C to +125°C
- Voltage Supply: 9 to 6 VDC
- Output Signal: – 0-10 VDC or 0-5 VDC at 12 VDC
- Low-Level Alarm Output: Switch-to-ground at 12% of active probe length
- Environmental Protection: IP68 (Liquid Side), IP67 (connector side)
- Mechanical Customisation: Available in lengths from 80mm to 300mm with a variety of thread and connector types
With a robust construction including Brass, PTFE, fluorosilicone seals and glass-filled nylon, and meeting stringent EMC standards to EN ISO 13766, T/LL470 engineered for reliability in off-road vehicles, generators and heavy-duty industrial machinery.
