1. Introduction of LLC series industrial grade of photoelectric liquid level sensor:
         The LLC series liquid level sensors (industrial grade, photoelectric water immersion sensors) are designed for industrial applications. Competent for heavy-duty environments in industrial applications. This series of products is suitable for a wide voltage range power supply environment, the drive current can reach 250mA. Therefore, this series of sensors can directly drive alarms and other equipment.

Second, the characteristics of photoelectric liquid level sensor LLC series (industrial grade):
         1) M12 or 1/2” SAE interface
         2) Three-wire electrical interface
         3) 250mA output
         4) There are two types of room temperature and high temperature versions (high temperature up to 125 degrees Celsius)

3. Typical application of photoelectric liquid level sensor LLC series industrial grade:
          ----Detection of machine oil, heat dissipation agent and refrigerant level
          ----Gear box, transmission box oil level detection
          ----Pump and gearbox liquid level detection
