T/LL25X Series Liquid Level Sensor
The T/LL415 Liquid Level Sensor is an advanced capacitive level sensor that continuously monitors liquid level and temperature and broadcasts this via a CAN J1939 output protocol
The T/LL250 series is designed for use in vented tanks requiring continuous level measurement of their contents and provides a factory set linear voltage or 4-20 mA output suitable for connecting into a PLC or process related applications. (The T/LL250 is not a loop powered sensor).
The device has no moving parts and utilises hydrostatic technology incorporating a pressure transducer to measure the height of liquid. The flexible tube allows the sensor to be fitted easily and to tanks where a
swing arm device is not practical.
Available in multiple lengths upto 10m and re-calibratable by end user. units supplied will be calibrated for diesel.
