The wireless pressure transmitter uses a diffused silicon pressure sensor based on the LORA wireless transmission pressure transmitter. The wireless pressure transmitter system is divided into a meter terminal transmitter and a collection terminal. The acquisition terminal can display the pressure in real time and is connected via a USB interface. The signal is transmitted to the computer, and our company also provides the customized service of the upper computer, which differentiates to meet the needs of customers.
The instrument terminal is powered by battery and has low power consumption.
The speed at which data is collected can be set at the display terminal, which is convenient and reliable.
The wireless terminal can be displayed with or without display, and can be equipped with a mechanical display to meet the needs of differentiation.
