Description:
This series products are low-power digital display temperature transmitter with wireless transmission function.
it adopts explosion-proof aluminum case and SS304 main structure , built-in high-precision PT100 as temperature measuring component, stainless steel probe insert type, can be tightly sealed with national standard thread. Circuit board is adopted low-power design, with the temperature compensation , and the accuracy is better than 0.1 °C. The wireless transmission mode has GPRS, LoRa ,NB-IoT & ZigBee to optional .
GPRS transmission, with the mature GPRS network of China Mobile, it can uploads the temperature of the site to the IP address specified by the customer. The user can set parameters by pressing a button or remotely.
LoRa transmission, used with LoRa gateway, has the advantages of low power consumption, long transmission distance (more than 3KM), strong signal penetration, and self-organizing network, which is especially suitable for LAN requirements in industrial parks.
NB-IoT transmission , which has the advantages of low power consumption, high transmission efficiency and low fee .
ZigBee transmission , which has the advantages of short distance, low complexity, self-organizing network, low power consumption, and low data rate.

Explosion-proof Principle:
It uses the gap flameproof principle and designs the sufficient
strength junction box and other part. All the components which can
cause a spark, arc and dangerous temperature are sealed in the
junction box When it happen explosion in the cavity, the joint side
can make flameout and cool, to prevent the flame and temperature
after explosion from spreading out of the cavity.
