How do I buy cold chain temperature monitoring devices?

When we search for cold chain temperature monitoring devices on the Internet, the web page will recommend many products to us. Some of these products are called cold chain temperature monitoring devices, and some are called cold chain temperature monitoring devices and humidity. Careful comparison did not reveal any obvious difference. Why do they label them like that?

First of all, it is different from cold chain temperature monitoring devices, which is a kind of detection device. It can perceive the measured information and convert the perceived information into electrical signals or other required information output according to certain rules. To meet the requirements of information transmission, processing, storage, display, recording and control. A transmitter is a converter that converts a non-standard electrical signal to a standard electrical signal according to an instruction. It can be said that on the basis of cold chain temperature monitoring devices, the transmitter converts the information transmitted by cold chain temperature monitoring devices into regular output signals according to the instructions. Such as 485 transmitter, analog transmitter, GPRS transmitter and so on.

With the development of modern industry, cold chain temperature monitoring devices are widely used in various industries. cold chain temperature monitoring devices are used to monitor various parameters in the production process to ensure the normal operation of equipment. On the basis of improving production capacity, the quality of products can also be guaranteed. Some say that excellent cold chain temperature monitoring devices will become the basis of modern production.

Cold chain temperature monitoring devices and transmitters together constitute an automatic control monitoring signal source. Different physical quantities require different cold chain temperature monitoring devices and corresponding transmitters. cold chain temperature monitoring devices The working principles and operating conditions of cold chain temperature monitoring devices vary with the type of measured parameters. Therefore, the types and specifications of cold chain temperature monitoring devices are very complex. The following is a centralized classification of cold chain temperature monitoring devices:

Distinguish the categories of measurement objects, such as measuring temperature, humidity, pressure, liquid level, light, ultraviolet, gas and other non-electricity, The corresponding cold chain temperature monitoring devices are called cold chain temperature monitoring devices and humidity cold chain temperature monitoring devices, pressure cold chain temperature monitoring devices, liquid level cold chain temperature monitoring devices, light cold chain temperature monitoring devices, gas cold chain temperature monitoring devices, this naming method allows users to quickly find the products they need.

According to the working detection principle, there are resistance, capacitance, inductance, piezoelectric, electromagnetic, magnetoresistive, photoelectric, piezoresistive, thermoelectric, nuclear radiation and semiconductor cold chain temperature monitoring devices. It is convenient for R&D personnel of cold chain temperature monitoring devices to conduct inductance analysis and research from the principle and design.

Based on the distance between the cold chain temperature monitoring devices and the object being measured, It can be divided into contact cold chain temperature monitoring devices and non-contact cold chain temperature monitoring devices. Non-contact cold chain temperature monitoring devices can monitor the numerical changes of objects in high risk and high temperature environments, such as infrared temperature cold chain temperature monitoring devices, It makes it easy for users to measure objects that are difficult to access or move.

It can be divided into active cold chain temperature monitoring devices and passive cold chain temperature monitoring devices according to the action form. Active cold chain temperature monitoring devices can detect changes in the detected signal in the measured object, or the signal is formed by the action of the detected signal in the measured object. Passive cold chain temperature monitoring devices only receive signals generated by the object being measured, such as infrared thermometers commonly used in homes.

Among the many types of cold chain temperature monitoring devices, temperature and humidity cold chain temperature monitoring devices is one of the most commonly used. To protect the accuracy and stability of the measured values, the humidity cold chain temperature monitoring devices are non-hermetically sealed. If used in dusty environments, it is recommended to choose a temperature and humidity transmitter with a built-in PE probe.

In addition, the measurement range needs to be selected according to the environment in which the temperature and humidity cold chain temperature monitoring devices are used. By default, the temperature and humidity ranges from -40 ° C to +80 ° C, the humidity ranges from 0%RH to 100%RH, and the ultra-high temperature ranges from -100 ° C to +300 ° C. In actual use, the impact of dust, oil and harmful gases should be considered, and the product with large drift should be selected to ensure that the product can be used for a long time.
