EE381

EE381系列紧凑型油中水分变送器是在线监测油品中的微量水分的理想选择,通过该监测可有效提前预防机械和设备的损伤以达到保护效果。EE381变送器拥有外壳坚固、测量精度高和优越的长期稳定性等特点。

  • EE381油中水分变送器

    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。

    FAQ

    Calibration for a specific oil is a laboratory procedure for determining the saturation curve of the oil. The saturation curve 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).

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

    Please see the cleaning instructions.

    No, coating is not available for the E+E MIO sensors.

    The standard scope of supply of E+E MIO sensors includes 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".

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

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