RFID Temperature Measurement Solution

Introduction

There are many technical methods of temperature measurement, each of them has its own advantage and adapted scenarios to use. In this article we makes some comparison of those methods’ difference. Especially, we will introduce out RFID temperature measurement solution. CXJ is committed to supply customers with low-cost, high-quality and long-lasting RFID solutions for various applications.

Comparison of RFID Temperature Measurement with Others:


No.	Method	Range	Applications	Advantages & Disadvantages
1	RFID UHF Temperature Measurement	3 – 5m	Bearing and mixer、cold chain、high heat oven、Power switch cabinet, etc.	Advantages: Non-contact recognition of temperature, fast response, high precision, and multi-point temperature measurement; Disadvantages: high cost of a single set and complicated equipment. Narrow temperature measurement range, -40~150
2	RFID HF Temperature Measurement	10 cm	Cold chain	Advantages: self-contained battery, temperature recordable. Disadvantages: The transmission distance is short, and the usage scenarios are limited. Battery needs to be replaced
3	Thermocouple	Wired	Burner, steam drum, steam generator	Advantages: small size, easy installation. The response speed is fast; the temperature measurement range is wide; the temperature measurement accuracy is high. Disadvantages: wired connection, limited usage scenarios
4	Infrared	0.5 – 2m	Industrial inspection	Advantages: wide temperature measurement range, high precision, easy to carry
5	RTD	Wired	Most industrial temperature measurement scenarios	Advantages: Wide temperature measurement range and high temperature measurement accuracy. Disadvantage: Wired connection

Successful Cases

Case 1 - Vaccine Cold Chain Temperature Measurement

The demand for traceability and temperature monitoring of cold chain transportation (especially pharmaceuticals, vaccines, and fresh products) is increasing day by day, from the original only sensing the storage environment temperature to the single-item-level real-time monitoring and traceability based on the smallest package.

Compared with RFID UHF temperature measurement and other temperature measurement methods, this method can upload items temperature in real time.

Case 2 - Industrial Bearings and Agitators Temperature Measurement

When the bearing and the Agitator rotate at high speed for a long time, it is easy to cause high temperature and even on fire. Typical temperature sensors are wired and difficult to install. This scenario is more suitable for RFID ultra-high temperature measurement.

Case 3 - Lithium Battery Warehouse Temperature Measurement

When storing lithium batteries in warehouses, the short circuit of individual batteries can easily cause fires. Therefore, it is necessary to measure the temperature of each small storage unit. In this scenario, neither thermocouples nor infrared thermometers are capable of real-time stable temperature measurement.

The RFID UHF temperature measurement solution is more suitable for temperature measurement of lithium battery warehouses. The advantage is that a set of reading and writing equipment and software can control hundreds of temperature measurement points. In the same case, the thermocouple needs to be deployed on 100 lines,, and the infrared thermometer cannot complete the temperature measurement.
