EE381可测量水活性和温度,同时也可计算出变压器油、润滑油、液压油和柴油中的绝对水含量值。

测量值可通过两路模拟信号输出,并在LCD显示屏上显示出来。

变送器的螺纹接口能调节变送器转向任意安装角度,以确保显示模块和电缆出线朝向合理的位置。

免费的组态软件EE-PCS可以方便的修改模拟输出信号和设置报警点,还可用来校准及调节变送器。

EE381 FAQ

  • What is the calibration for a specific oil? What are specific oil parameter?

    Calibration for a specific oil is a laboratory procedure for determining the saturation curve of the oil. The saturation curved is described by two parameters (A and B). These parameters are used for setting up the moisture in oil sensor for correct calculation of the water content (ppm) out of the measured temperature and water activity (aw).

     

  • How can I replace the sensing element of the E+E MIO sensor?

    Sensor replacement is possible the EE360 models when option PC4 (pluggable probe). Please see the operation manual for detail and spare part code ordering guide.

     

  • How can I clean the sensing element of the E+E MIO sensor?

    Please see the cleaning instructions.

     

  • Can the coating be used for E+E MIO sensors?

    No, coating is not available for MIO sensors.

     

  • What kind of calibration certificate is included in the standard scope of supply of the E+E MIO sensors?

    The standard scope of supply of E+E MIO sensorsincludes an inspection certificate according DIN EN 10204 - 3.1. For details on calibration certificates please see our white paper "Calibration and Traceability in Measuring Technology".

     

  • Are there different A, B parameters for mineral transformer oil from various manufacturers?

    No, mineral transformer oils from different manufacturers are quite similar.. A and B parameters are the same.

     

  • What is the difference between a 2 wire and a 3 wire current output?

    Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
