T/LL400 - Extended Temperature Range Level Sensor
Vertically mounted liquid level sensor suitable for use in temperatures from -40°C to +125°C. Voltage output with connector options including integrated Deutsch or Delphi Metri-pack or flying leads.
*Alternative Outputs are available on request
The T/LL400 LiquidLevel Sensoris an advanced capacitance sensor that continuously monitors liquidlevel providing a configurable voltage output in the range 0-10 VDC.Compact androbust this sensor is designed to provide accurate and repeatable liquid level data. It is ideal forextended temperature range applications such as monitoringengine oilor coolantin relatively shallow, sumps or tanks.
