This NB-IOT wireless pressure
sensor is my company's independent research and development of low-power
wireless transmission digital pressure transmitter, it is battery-powered.
It has
a variety of wireless transmission methods, including GPRS/LORA/NB-IOT .A
variety of transmission methods can be selected.
It uses explosion-proof cast aluminum shell
and 304 stainless steel joints, built-in high-precision pressure sensor,
equipped with LCD display. IT can measure gas, liquid, oil and other stainless
steel non-corrosive media, with strong media compatibility and so on.
It has zero clearing, backlight, switchgear,
unit switching, low voltage alarm and other auxiliary functions.
The sensor acquisition speed can be set, the
frequency can be set, high and low alarm value can be set, immediate pressure
alarm and other functions.
Lora Transmission has Lora Gateway use, low
power consumption, long transmission distance, strong signal penetration, self-networking
and other advantages.
NB-IOT
Transmission has used the latest NB-IOT technology, low power consumption, high
transmission efficiency, low fees and other advantages.
