Features, keys
- High precision
Thanks to the latest circuit design, this unit offers high precision and high resolution, and it can measure minute changes in the level.
A circuit is employed to correct liquid adhesion to the electrode. - Applied for the intrinsically safe explosion-proof certificate in accordance with the IEC International Standard.
We applied for and obtained the latest ExiaIICT5 standard, intrinsically safe explosion-proof certificate. - Can operate in harsh environments
This meter can make stable measurements in harsh environments at high temperatures and pressures. - Simple to adjust
It is easy to make the initial settings and span adjustment, using pushbuttons. - Various functions are included to meet different field conditions
You can adjust the response speed using the delay setting function.
Since these units can handle a wide range of power supply specifications (24 to 250 VAC, DC), they can be used in any location in the world. - Can be used in a simple configuration since the unit consists of only two components, the sensor and the relay isolator.

Adjustment function
This unit eliminates the inconvenience of making initial settings that is necessary with ordinary models.
You can simply set the initial settings using one-touch pushbuttons.
Usages, use examples
- Measures the remained quantity of liquid, powder or granulated material in various tanks. Measures the location of a material interface and bubbles in liquids.
- Can be used with conductive or insulating liquids, insulating liquids with a small dielectric constant, and semi-conductive liquids.
Ex.: Various oils, chemical solutions (acids, alkalies), washing liquids, tap water, pure water, distilled water, alcohol, etc. - Small tanks, mid-sized tanks, fuel tanks, oil tanks, underground pits, etc.
- Chemical, petroleum, energy, food, pharmaceutical, boilers, high temperature and high-pressure tanks, various chemical-agent tanks.
