Product Introduction
I. Industrial GradePhotoelectric Liquid Level Sensor/Photoelectric Liquid Level SwitchLLC200D324-003 Overview
The LLC industrial-grade level sensor features single-point detection and TTL-compatible digital level signal output. This sensor is suitable for high-power output applications and can directly drive incandescent indicator lamps, audible alarms, relays, or other situations. An infrared LED light source and phototransistor detector are well mounted on the base of the sensing end to ensure good optical coupling in air. When the sensing end is immersed in liquid, the infrared light will be transmitted out from the conical surface, and the light intensity received by the phototransistor will decrease, causing the output level to change. Various output circuits can meet different application requirements.
II. Cleaning Method for Industrial Photoelectric Liquid Level Sensor/Photoelectric Liquid Level Switch LLC200D324-003
Choose different cleaning solutions based on the contaminants. The original manufacturer recommends using Freon and alcohol solvents. Chlorine-based solvents such as trichloroethane are prohibited as they can harm the sensor material.
III. Liquid Medium Compatibility for Industrial Photoelectric Liquid Level Sensor/Photoelectric Liquid Level Switch LLC200D324-003
Before use, check whether the target liquid is compatible with PSU or Trogamid materials.
