Capacitance Liquid Level Sensor | T/LL171 & T/LL174
T/LL171 and T/LL174 are vertically mounted, highly advanced sensors designed to continuously measure the height of the liquid for use in fuels and water based liquids such as engine coolant. Occupying a tiny footprint, the sensors are available in lengths between 90 and 500 mm long. The T/LL171 provides a current output whereas the T/LL174 provides a voltage 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/LL17x series can be used in very shallow tanks without detriment to its accuracy. The T/LL17x 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
