Low Stock, 5 left
Product Description
The AN-203A is a wireless level transmitter based on LoRaWAN standard protocol. It features a ceramic capacitive pressure sensor, which is resistant to clogging, easy to clean, and offers excellent corrosion resistance. Advanced digital circuit technology is employed, incorporating zero tracking, linearity compensation, and temperature compensation functions. Leveraging the spread spectrum communication technology of LoRa, coupled with a high-gain external antenna, the device ensures better transmission and reception of wireless signals, thereby extending the wireless communication range. With its low power consumption and built-in high-capacity battery, the AN-203A ensures a long operational lifespan and service cycle.
The AN-203A is easy to install and maintain, can be installed in pole-mounted or wall-mounted. Suitable for water or liquid level measurement and monitoring in the fields of property fire-fighting, industry, petroleum, power plant, mining, urban water supply and drainage, hydrological exploration, etc.
