How do I buy a temperature tracking device?

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

First of all, the temperature tracking device is different from the temperature tracking device. It can sense the measured information and convert the perceived information into electrical signals or other required information output according to certain rules, so as 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 the transmitter is based on the temperature tracking device and converts the information transmitted by the temperature tracking device into a regular output signal according to the instruction, such as 485 transmitters, analog transmitters, GPRS transmitters, etc.

With the development of modern industry, temperature tracking devices are widely used in various industries. The temperature tracking device is used to monitor various parameters during the production process to ensure the normal running of the device. On the basis of improving production capacity, the quality of products can also be guaranteed. Some say that excellent temperature tracking devices will become the basis of modern production.

The temperature tracking device and transmitter together constitute an automatic control monitoring signal source. Different physical quantities require different temperature tracking devices and corresponding transmitters. temperature tracking device The working principles and usage conditions vary with the type of the parameter to be measured. Therefore, the types and specifications of temperature tracking devices are very complex. The following is a centralized classification of temperature tracking devices:

Distinguish the categories of measurement objects, such as measuring temperature, humidity, pressure, liquid level, light, ultraviolet, gas and other non-electricity, The corresponding temperature tracking device is called the temperature tracking device, humidity temperature tracking device, and pressure temperature tracking device device, liquid level temperature tracking device, light temperature tracking device, gas temperature tracking device, this naming method is convenient for users to quickly find the product they need.

According to the working detection principle, there are resistance, capacitance, inductance, piezoelectric, electromagnetic, magnetoresistive, photoelectric, piezoresistive, thermoelectric, nuclear radiation and semiconductor temperature tracking device. Convenient temperature tracking device developers from the principle and design of inductance analysis and research.

According to the distance between the temperature tracking device and the measured object, it can be divided into contact temperature tracking device and non-contact temperature tracking device. Non-contact temperature tracking devices can monitor the numerical changes of objects in high-risk and high-temperature environments, such as infrared temperature tracking devices, which can facilitate users to measure difficult to access or move targets.

It can be divided into active temperature tracking device and passive temperature tracking device according to the action form. The active temperature tracking device 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 temperature tracking devices only receive signals generated by the object being measured, such as infrared thermometers commonly used in homes.

Among the many types of temperature tracking devices, temperature and humidity Temperature tracking devices are the most commonly used. To protect the accuracy and stability of the measured values, the humidity temperature tracking device is 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 temperature tracking device is 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.
