Products Description
This wireless pressure transmitter, based on 4G/NB-IoT wireless communication, consists of core components including a die-cast aluminum alloy housing, a main control system, an LCD display, measurement circuitry, mechanical connectors, and a diffused silicon sensor. It supports various threaded mounting methods, accommodates a wide range of pressure ranges, and supports measurement of high-temperature media up to 150°C. By default, it measures relative pressure (gauge pressure) for media such as gases, liquids, and steam. It can be modified to measure absolute pressure (gauge pressure + atmospheric pressure) and negative pressure based on project needs.
