Microcomputer Sensing Co The KL-620 Microcomputer Sensing Control equipment is a comprehensive sensor / transducer control training system. Its modular and closed-loop control circuits allow implementation of open-ended, individual control loops used in industrial applications. The uses only industrial-standard sensors / transducers (0~10V, 4~20mA) and is equipped with USB for computer interface control experiments. Control programs can be written and downloaded to the Single-Chip microprocessor on KL-61001A main unit from computer through USB interface.ntrol Equipment- Photo Transistor / Interrupter & Hall Effect Sensor - Pyroelectric Detector & Reed Switch &Thermistor & Mercury Switch Sensor - Limit Switch & Vibration Switch & Condenser / Dynamic Microphone Sensor - Gas / Smoke & Ethanol Sensor - AD590 Temperature & Humidity Sensor - Infrared TX / RX & Ultrasonic TX / RX Sensor - Pressure & Strain Gauge Sensor - Hall Current & Proximity Sensor - CDS & Photovoltaic Sensor - V/F Converter - F/V Converter - RTD (PT-100) Sensor - Level (Water) Sensor - Fiber Optics Communication - LVDT Sensor - Rotation Angle Sensor- Industrial-standard sensors and transducers - With USB interface - Open-ended design, ideal for expansion - Offer a sensing data acquisition software
