The wireless temperature measurement thermocouple sensor is a wireless temperature monitoring system developed by our company for use in stacking rotating liquid tanks and other environments . It has the technical characteristics of high accuracy, low power consumption, long transmission distance, high temperature resistance, good real-time performance, wireless transmission, no wiring required , low construction difficulty, time-saving and labor-saving, and long service life. It can replace most probe-type temperature monitoring sensors and is suitable for transformer temperature measurement, forest fire prevention, pharmaceutical production equipment, chemical equipment, rotary kilns, tanks, coal piles, grain depots, wine cellars, material stacks, warehouses, rotating electrical equipment, etc., for real-time temperature control to ensure product quality and production safety during the production process.
Sensor wireless transmission can adopt a variety of modulation methods, which are divided into FSK, LORA and NB-IOT. FSK is suitable for environments with short distances, high product volume requirements, high measurement frequency, long service life, and dense measured points. LORA is suitable for environments with long distances, relatively scattered measured points, high measurement accuracy requirements, and moderate measurement frequencies. NB-IOT is suitable for environments with good mobile networks, scattered measured points, low measurement frequencies, and low response requirements.
Inner Mongolia Deming Electronic Technology Co., Ltd. is a company integrating R&D, production, sales and after-sales service. The company relies on its strong technological advantages and intelligent control core to continuously expand its application areas. The industry covers wireless LORA sensors, NB-IOT temperature and humidity

Pros/Cons
K-Type
-200~+1300℃
±1.5℃
±2.5℃
It is cheap, widely used, and suitable for use in oxidizing and inert atmospheres. Bare wire is not suitable for use in vacuum , carbon-containing, sulfur-containing, and redox alternating atmospheres. The high-temperature thermoelectric potential rate stability is not as good as that of N type.
J-Type
-200~+950℃
±1.5℃
±2.5℃
The price is cheap, the thermoelectric potential rate is larger than that of K type, it can be used in both oxidizing and reducing atmospheres, it is resistant to H2 and CO corrosion/it cannot be used in sulfur-containing atmospheres, after exceeding 538℃, the iron pole oxidizes quickly, the temperature resistance is not high enough, and it cannot be used in high temperature areas
Type E
-200~+850℃
±1.5℃
±2.5℃
Cheap price, maximum thermal electromotive force rate, high sensitivity / low temperature resistance, no
Other characteristics are similar to K type.
N-type
-200~+1300℃
±1.5℃
±2.5℃
Cheap, strong high temperature oxidation resistance, nuclear radiation resistance, ultra-low temperature resistance, good long-term stability of thermal electromotive force rate/low thermal electromotive force rate, launched later than other types, not widely used
T-Type
-200~+350℃
±0.5℃
±1.0℃
Cheap, high precision / poor oxidation resistance, not resistant to high temperature
S/R type
-200~+1600℃
±1.0℃
±1.5℃
