This NB-IOT wireless temperature
sensor is my company's independent research and development of low-power
wireless transmission digital temperature 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 temperature 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 temperature 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.
l Low power design, battery-powered, long duration
l Optional battery-powered, power-supply mode
l GPRS/LORA/NB-IOT a wide range of wireless transmission options
l 304 stainless steel housing and connectors, 316L stainless steel
diaphragm, strong media compatibility
l -200~1500℃ full range coverage
