K7L-AT50D-S

Level Controllers Liquid Leakage Sensor Amplifier with Disconnection Detection Function K7L-AT50D/-AT50D-S Detect disconnections between the Sensor Amplifier and a Terminator connected to the end of the Sensing Band. Constantly monitors for disconnections between the Sensor Amplifier and the Sensing Band. Failure to detect liquid leakage due to disconnection in the Sensing Band prevented. Notification of disconnection detection made using LED indicator and transistor output. After a disconnection is detected, in order to avoid instability due to further contact of the disconnected part, the operating status is held. This model retains all the characteristics of the K7L-AT50 (detection sensitivity, sensing ranges, and AC detection method). Meets UL/CSA standards. (See information on standards on page 31.) Application Examples Liquid Leakage Detection for Measuring Baths in CMP Devices Detects liquid leaked to drain pans, and prevents damage to devices and cleaning irregularities for wafers. Detection of Liquid Leakage at Pipe Joints for Chemical Liquid Tanks Liquid leakage at a pipe joint can be detected by wrapping the Sensing Band around the joint. Detection of Condensation and Liquid Leakage at Semiconductor Production Installations Detects condensation inside cleaning devices and liquid leaked to the surroundings. Detection of Cleaning Fluid Level for Plating Devices Detects the level of pure water inside plating baths. High sensitivity allows high-accura...
