描述
Products Features:
AR3461 wireless pressure transmitter is a wireless Internet of things transmitter based on Nb lot. The diffusion pressure sensor and PT100 temperature sensor are used for signal acquisition. The product has the characteristics of high precision, high stability and low power consumption. It is suitable for long-distance and long-term measurement of pressure and temperature, and supports local display function.
The product adopts Wide LCD display and supports local parameter setting, which greatly facilitates the field use.
The product can be widely used in petroleum production, chemical production, urban pipe network water supply, scientific research and other fields, and used for remote on-site
