Moisture meter (in oil)
WGL series
- Moisture meter in oil that can be used onlineUltra-high sensitivity even in a small size. Moisture meter ideal for incorporating equipment
-
By using the difference in permittivity between oil and water and measuring the change in capacitance, the water content in the oil is detected.When water is mixed in oil, the water causes "rust and corrosion", and also causes deterioration of oil performance and properties, oxidation, and so on. This product enables these quality controls.
*Heavy oil, turbine oil for power plants, lubricating oil for hydraulic equipment, rolling oil for steelworks, etc.We have a lineup of CGL type dedicated to level measurement and WGL type compatible with moisture meters and analyzers.
Features, keys
- Achieves ultra-high sensitivity and high accuracy even in a small
size
High accuracy (± 1% accuracy) is achieved even in short size (height 50-60 mm) level measurement. The separation amplifier is also the size of a business card and can be easily incorporated into a small device.
- Displaying measured values in real time with a display
The display is mounted on a separating amplifier.The current measured value (% display) and capacitance value (pF display) are displayed in real time.
- Simple initial setting
It is easy to make the zero and span setting, using pushbuttons. - BNC connecter make it easy to connect and disconnect the sensor and cable
Reduces connection mistakes between the sensor electrode cable and the separating amplifier.
Applications
It can be used as an oil deterioration alarm or oil checker by measuring the water content in the oil. Since the dielectric constants of oil and water are significantly different, the capacitance is measured using the difference, and the water content in the oil is continuously measured by the change in the dielectric constant. It is also possible to install the sensor electrode in the middle of the piping.
