IPD57L pressure transmitter, uses silicon diaphragm sensor or capacitance sensor, with stainless steel housing, using professional IC circuit over a wide temperature range of zero and full scale performance compensation. So it can detect a large number of monitoring points in the wide region real-time data of the network systems, such as the liquid tank testing, storage tanks and oil and water pressure monitor, other industrial field automation control.
With LoRaWAN® module, it transmits the pressure via gateway to networks server and application server. User can monitor the status remotely. It is optional for different frequency, such as 470Mhz (China), 868Mhz (Europe), 915Mhz(USA), 923Mhz (Australia). As it is with algorithm of low power consumption, the internal battery can work for more than 1 years for one charge (With different parameter, 3 years lifetime is realized).
1) More than 3 years battery life
2) -141dBm sensitivity
3) 10,000m emission distance in the view area
4) Through the gateway, it can upload the data into cloud
5) Can be in the chemical industry, metallurgy industry, oil and electricity automatic field
