T/LL405 ExtendedTemperature Range LiquidLevel Sensor
The T/LL405 Liquid Level Sensor is an advanced capacitance sensor that continuously monitors liquid level providing a configurable voltage output in the range 0.5-4.5VDC.
The T/LL405 Liquid Level Sensor is an advanced capacitance sensor that continuously monitors
liquid level providing a configurable voltage output in the range 0.5-4.5VDC. Compact and robust this sensor is designed to provide accurate and repeatable liquid level data. It is ideal for extended temperature range applications such as monitoring engine oil or coolant in relatively shallow sumps or tanks.
