Products Description
Pl321 anti-explosion ultrasonic sensor is a high protection class and multi-function type measuring instrument. It is all sealed guard and up to IP68 protection class and suitable for high temperature and easily explosive environment. With a wide range of temperature compensation and the original ERD interference intelligent recognition system, the measurement can achieve high accuracy and stability. It can be used to measure distance or level, and the value would displayed in LED or LCD and transmitted a great distance.
