Product Introduction
I. Overview of Industrial Photoelectric Liquid Level Sensor/Photoelectric Liquid Level Switch LLC210D324-003:
LLC industrial gradeLevel Sensorsis single-point detection, TTL-compatible digital level signal output. This sensor is suitable for high-power output applications and can directly drive incandescent indicator lights, sound alarms, relays, or other situations. An infrared LED light source and phototransistor detector are precisely mounted on the base of the sensing end to ensure good optical coupling in air. When the sensing end is immersed in liquid, 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. Diverse output circuits can meet different application scenarios.
II. Cleaning Method for Industrial Photoelectric Liquid Level Sensor/Photoelectric Liquid Level Switch LLC210D324-003:
Choose different cleaning solutions according to 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 of Industrial Photoelectric Liquid Level Sensor/Photoelectric Liquid Level Switch LLC210D324-003:
Before use, check whether the target liquid is compatible with PSU or Trogamid materials.
