last update: September 10, 2018

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.

Inter-electrode Resistance Detection

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.

AC Detection Method

The K7L internally oscillates AC signals provided to the Sensing Band, protecting the Sensing Band from electric corrosion and ensuring safe operation.

Noise Canceller Function (Patent Pending)

The K7L incorporates a noise canceller circuit that uses a 3-conductor cable, ensuring a high level of noise immunity.

Multi-channel Applications

Isolation between the power supply circuits and sensing circuits allows multiple channels to be installed in the same location.

Detection of Condensation and Liquid Leakage at Semiconductor Production Installations

Detection is also possible for condensation inside cleaning devices and liquid leaked to the surroundings.

Sensing Band with Excellent Chemical Resistance

SUS316 and polyethylene are used for the Sensing Band's core and sheath to ensure high resistance to both acidic and alkaline liquids.

Detection of Liquid Leakage at Pipe Joints for Liquid Chemical Tanks

Liquid leakage at a pipe joint can be detected by wrapping the Sensing Band around the joint.

Liquid Leakage Detection for Measuring Baths in CMP Devices

Liquid leaked to drain pans can be detected to prevent damage to devices and cleaning irregularities for wafers.

Detection of Cleaning Fluid Level for Plating Devices

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.

Specifications

Rated power supply
voltage 12 to 24 VDC (Allowable voltage fluctuation range: 10 to 30 VDC)
Operate resistance Ω to 50 MΩ, variable
Range 0: 0 to 250 kΩ. Range 1: 0 to 600 kΩ
Range 2: 0 to 5 kΩ. Range 3: 0 to 50 kΩ
Note:
The range is set using the DIP switch on the side of the Sensor Amplifier. (Refer to DIP Switch
Settings.)
Set the corresponding pin of the DIP switch in the up position. (For range 0, set all 3 pins in the
down position.) The adjuster (ADJUST) on the top of the Sensor Amplifier sets the resistance
value for detection within the set range. It is factory-set to the upper limit. (Normally, the K7L
can be used with the adjuster at this setting.) With any range, resistance values can be set from
0 Ω.
Disconnection
