Product Description


LCT-840 Capacitive Level transmitter
Overview
 The principle of the LCT-840 capacitive liquid level transmitter is to use the capacitance formed by filling the liquid medium between the positive and negative probes to change the capacitance (the amount of change in the liquid level) into a standard electrical signal output. The core components of the product are highly integrated, dedicated capacitance measuring chips with precise temperature compensation and linear correction for high precision, high stability, safety, reliability and continuous measurement.

Features:
  1.  The fuel consumption value is obtained directly by measuring the oil volume of the oil drum, and does not have any effect or influence on the oil pipe.
  2.  It can be fixed by thread or flange and is easy to operate.
  3. The sensor can be customized according to different oil drum sizes of the customer; it adds temperature compensation function to automatically correct the error caused by the volume change of the oil drum caused by temperature change.
  4. The capacitive sensor is directly installed in the oil drain hole of the oil drum, and the NPT taper pipe thread is used to prevent the oil leakage problem.
  5. Without any mechanical moving parts, mature and stable circuit structure and high quality components will make the sensor continuous use.
