Rochester T/LL171 Liquid Level Sensor

The T/LL171 is a highly advanced sensor designed to continuously measure the height of the liquid, typically fuel or coolant level in a tank and provides a 4-20mA output. Although the sensor is not a loop powered device, it is suitable for use in difficult and hostile environments.

 

The sensor has a very small footprint with its advanced electronics being housed in the hexagon header.

 

Unusually for solid-state liquid level sensors, the T/LL171 series can be used in very shallow tanks without detriment to its accuracy.

 

The T/LL171 has an integral Packard Metri-pak 150 series connector but can also be supplied with a flying lead and a suitable connector of your choice.
