Capacitance liquid level sensor

The Model T/LL350 series provides a continuous level measurement of tank contents and offers a choice of voltage, resistance or 4-20 mA outputs. The dual probe design allows the sensor to continuously self calibrate and detect, for example, different fuels, and will recalibrate the output to compensate for differing dielectric constants. Therefore, if a tank is filled with conventional diesel and then bio-diesel, the sensor automatically calibrates to give a corrected output without the need for the user’s intervention.

T/LL350系列提供油箱内容物的连续液位测量，并提供电压、电阻或4-20mA输出选项。双探头设计允许传感器连续自校准和检测，例如不同的燃料，并将重新校准输出以补偿不同的介电常数。因此，如果油箱先装满传统柴油，然后再装满生物柴油，传感器会自动校准以给出校正的输出，而不需要用户的干预。
