OM-13 (Non-explosion-proof oil moisture meter)
It inherits the functions of the OM-11 type which has been highly evaluated and patronized is even smaller and easier to handle.
You just send the sample oil to us! We will calibrate the oil.
Easy installation and close monitoring !!
The amount of water in the oil can be measured in real time!
You just pass the oil through the piping where the electrodes are installed.
No adjustment work is required except for simple zero adjustment !!
Purpose
Measures the water content in oils such as heavy oil and lubricating oil. It can be used for monitoring and controlling the moisture level.
- The permittivity of oil is measured and the water content is continuously calculated based on the change because the permittivity of oil and water is significantly different (2 to 3 for oil / 80 for water).
- You pass oil through the electrodes of the coaxial cylindrical structure. Since one calibration is performed for each oil type, stable moisture measurement with high accuracy is possible.
- It has function that can handle several types of oil, and temperature compensation.
Principle of the meter moisture in oil
Application
Delivery example
When water is mixed in the oil, it promotes the oxidation of the oil, deteriorates the lubrication performance, and promotes rusting and corrosion of equipment. Moisture management in oil is necessary to improve the operating efficiency of equipment.
They've used for various moisture management.
It has function that can handle several types of oil, and temperature compensation.
Turbine oil for power plants, brake oil, edible oil, emulsion oil, lubricating oil for hydraulic equipment, rolling oil for steel mills, fuel oil for ships, etc.
Feature
●The converter and display are integrated, making it compact and easy to use.
●Due to the simple electrode structure, there is little pressure loss and it is very durable.
●You can stable moisture measurement because it uses a high-precision capacitance converter.
●Measurement error does not occur even if the oil temperature changes because the temperature is corrected.
●It can handle a wide variety of oils because the display has an oil type registration function.
Operating principle
●The transducer shows a "2" when the electrodes are filled with oil only and when only water is filled it shows "80".
※It captures the difference in permittivity. 80 is the permittivity of water and 2 is the permittivity of oil.
●If even one drop of water enters this state, the value indicated by the converter will change significantly to the positive side.
●If you adjust to let the converter display "0V" with nothing but oil and "1V" with 1% water, it will show "2V" with 2% water.
●Capacitance changes linearly with respect to moisture.
Component
Converter
The case is made of stainless steel which is resistant to rust and rot.
Wiring work is easy because there is space around the terminal block.
Control unit & Display
Displays the moisture value.
It is equipped with functions necessary for moisture management as upper/lower limit alarms and temperature compensation.
Electrode
Pipeline type (straight pipe type) is standard.
Just install it in the middle of the piping. Continuous moisture measurement !
Since simple structure, so there is no pressure loss and it is durable.
