EE364 On Line Moisture Transmitter , Oil Water Content Testing Equipment
Description:
The EE364 is an innovative moisture in oil transmitter, suitable for OEM applications. The high measurement accuracy and excellent long-term stability make the EE364 ideal for online monitoring of moisture in transformer, lubricating and hydraulic oil, as well as diesel fuel.The compact design and rugged stainless steel housing allow a space-saving installation in the most demanding applications.The EE364 measures water activity (aw), oil temperature (t) and calculates the absolute water content (x). The measured values are available on two 4-20mA outputs and one digital output with MODBUS RTU interface.The analog outputs can be individually scaled and configured using the optional converter cable and the free EE-PCS Product Configuration software.
Typical applications :
| Monitoring of | Measurement of water activity (aw), temperature and water content (x) in ppm Two configurable 4…20 mA outputs MODBUS-RTU interface Pressure rating 20 bar G ½" ISO or ½" NPT process connection |
| - Transformer oil | |
| - Lubrication oil | |
| - Hydraulic oil | |
| - Engine oil | |
| - Diesel fuel |
