This is a photoelectric switch that is composed of emitter and receptor. The emitter consists of a laser diode, and the laser has the characteristics of high precision, good orientation etc. The receptor consists of a photoelectric element. When receiving the laser pulse, the built-in light will con..
This is a photoelectric liquid level sensor that operates using optical principles. The advantages of this are good sensitivity and no need for mechanical parts - meaning less calibration! The corrosion resistant probe is easily mounted and can handle high temperature and high pressure. The sensor i..
