EE360 – Moisture in Oil Transmitter油中微水测量

High-end Device for Reliable Oil Condition Monitoring


工业现场对变压器油和润滑油中微量水分进行快速准确的测量对于设备机器的长期运转和定期维护十分重要。 益加义已经获得了Germanischer Lloyd 船舶认证委员会的DNV GL认证,产品能用于远洋船舶和海事船只。

对于变压器油而言,水分会破坏变压器油的绝缘特性,并对电力设备的安全生产构成隐患,所以对变压器油中的微量水分进行持续监测就非常有意义。

与空气的湿度相似,油中水分的含量可以用绝对值含水量[ppm] 或相对值水活性 [aw]来描述。

油中水份的测量:

如同可以测量空气中的湿度,EE360也能够用来测量油中水份。油中水分含量可以选择绝对含水量[ppm]或相对水活性[aw]的方式进行输出。
油中水份测量的典型应用有油的净化系统,石油平台上进行润滑油及齿轮油的在线监测、汽轮机润滑油检测。




The EE360 can be employed in oil up to 180 °C (356 °F) and 20 bar (290 psi). Themulti-functional display shows all measured values simultaneously andfacilitates configuration and adjustment of the transmitter. The built-in data logger stores 20.000 values per measurand and shows them as graph on the 3.5” TFT colour display. With the optional ball valve set the probe can be mounted and removed without process interruption.

 Pressure rating 20 bar (290 psi)压力20公斤

 Rugged IP65 polycarbonate enclosure防护等级IP65

 3.5“ TFT colour display with datalogger-function3.5寸大屏显示

 Analogue, relay and digital outputs电流或数字通信

The probe can be employed up to 180 °C (356 °F) and 20 bar (290 psi) and is available with either ISO or NPT slide fitting, which allows for variable immersion depth. 螺纹规格有ISO或NPTUsing the optional ball valve, the probe can be mounted or removed even without process interruption.可以在带压情况下安装,探头安装方便。

The design of the enclosure facilitates easy mounting and maintenance. EE360 is available with IP65 polycarbonate or stainless steel enclosure. The measured values are available on two analogue outputs and on the optional digital interface RS485 with Modbus RTU or Ethernet with Modbus TCP. An optional relays module can be used for alarms and process control.可以设置报警输出

The state of the art TFT colour display can show all measurands simultaneously and offers extensive error diagnostics. The integrated data loggingfunction saves all measured data in the internal memory. The logged data can be displayed in a graph directly on the device or easily downloaded via USB interface.

The EE360 configuration and adjustment can be performed either directly on the device via display and push buttons or with the free EE-PCS software using the USB service interface.
