SEM228V Aluminum UV Transmitter Sensor

SEM228V is an ultraviolet transmitter developed by our company. This product is based on the principle that a photosensitive element converts ultraviolet light into a measurable electrical signal to realize online monitoring of ultraviolet light. The circuit uses American imported industrial-grade microprocessor chips and imported high-precision ultraviolet sensors to ensure the excellent reliability and high precision of the product. The integrated sensor of the product is integrated and the measurement data is more comprehensive.

The circuit uses American imported industrial-grade microprocessor chips and imported high-precision ultraviolet sensors to ensure the excellent reliability and high precision of the product. The integrated sensor of the product is integrated and the measurement data is more comprehensive. The product outputs 485 signals (standard Modbus-RTU protocol), can communicate up to 2000 meters, and supports secondary development. The product shell has a high protection grade shell, and the protection grade is IP67.

This product can be widely used in environmental monitoring, weather monitoring, agriculture, forestry and other environments. Measure ultraviolet rays in the atmosphere and under artificial light sources.
