Sensing Bands boast high degree of chemical resistance. The K7L can be used in a wide range of applications, from semiconductor production installations to food-processing equipment.
Stable detection of liquids with impedances of up to 50 MΩ and common water. Four sensing ranges are available, ensuring detection suited to the application.
The K7L internally oscillates AC signals provided to the Sensing Band, protecting the Sensing Band from electric corrosion and ensuring safe operation.
The K7L incorporates a noise canceller circuit that uses a 3-conductor cable, ensuring a high level of noise immunity.
Isolation between the power supply circuits and sensing circuits allows multiple channels to be installed in the same location.
Detection is also possible for condensation inside cleaning devices and liquid leaked to the surroundings.
SUS316 and polyethylene are used for the Sensing Band's core and sheath to ensure high resistance to both acidic and alkaline liquids.
Liquid leakage at a pipe joint can be detected by wrapping the Sensing Band around the joint.
Liquid leaked to drain pans can be detected to prevent damage to devices and cleaning irregularities for wafers.
The level of pure water is detected inside plating baths. High sensitivity allows high-accuracy control to prevent cleaning irregularities.
Note: Be sure to ground the baths if two or more K7L Sensors are used in the same tank in an explosion-prevention area.
