ITD57L Temperature transmitter uses PT100 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 Temperature
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
