T/LL360 电容式液位传感器扩展温度范围

垂直安装的液位传感器,具有自动补偿液体电介质变化的功能。安装选项包括锥形螺纹或SAE 5孔法兰。可选择电流、电阻或电压等电气输出。

T/LL360是T/L350系列的扩展温度范围的变种,是一种高度先进的传感器,用于连续测量罐体中的内容物。T/LL360系列能够在-40°C的温度下工作,当使用不同介电常数的液体时,T/LL360系列会自动补偿。例如,如果在传统柴油罐中使用,用户可以用生物柴油重新加注,传感器会自动修正输出液位。

选项包括高/低液位报警点,可安装任何合适的接头和补偿非线性形状的油箱。

选项

Alarm: One position at either high level (switch to ground above level) or low level (switch to ground below level). Switch point can be set between 7% and 90% of measuring range (hysteresis 5%). Max load: 100mA.
Custom empty/full points: Specific empty and full levels can be provided within the allowable measurement range of the probe.
Non-linear Tanks: Compensation for non-linear tank shapes available.
#Connections: Any suitable customer specified connector can be fitted. Terminated wire ends should be fitted with suitably sealed connectors to maintain specified IP rating.

Ŧ Due to 3Ω resolution, accuracy of resistive output variants is specified accuracy ±3Ω.
