What are the probes of industrial temperature and humidity sensors?
Temperature and humidity are the physical quantities that people usually touch the most, and they are also a very important and common measurement parameter in the process of industrial and agricultural production. With the gradual maturity of sensor technology and the development of society, the demand for intelligence in information technology, industry, agriculture and other industries has also continued to increase. In order to improve the level of intelligence in the use of the industry, industrial-grade temperature and humidity sensors are increasingly being used in various industries, and the use of industrial temperature and humidity sensors in various industries is also becoming more and more large-scale.

Currently, single temperature sensors and temperature and humidity sensors are more commonly used. The probe is an important part of the sensor, and it is directly related to the accuracy and stability of the measured data. Regarding the probes of industrial sensors, the editor has sorted out the commonly used single temperature probes and temperature and humidity probes, let's take a look together!

1. Single temperature probe

The editor of single temperature probe organizes six commonly used probes, namely: flat probe, stainless steel probe, magnetic probe, quarter-pipe thread probe, ultra-low temperature probe and ultra-high temperature probe.

Flat probe

The flat probe has a large contact area and is suitable for measuring the temperature of the surface of an object. When measuring the surface temperature, the front end of the probe must be perpendicular to the measured object and fully and completely contact the measured object. It must be noted that the contact surface between the probe and the measured object must be flat, otherwise the measurement result will be affected during the temperature sensor measurement.

Stainless steel probe

The stainless steel probe is completely sealed, waterproof and dustproof, suitable for measuring the temperature of liquids. The sensor chip is inside the probe. When the probe is inserted into the liquid to be measured, it can protect the sensor from being damaged by water.

Magnetic probe

The probe is magnetic, suitable for measuring the temperature of magnetic material objects. The magnetic probe can be easily attached to the object for easy measurement.

Quad-pipe thread probe

The probe adopts the standard quarter-pipe thread, which is suitable for measuring the temperature inside the pipe.

Ultra-low temperature probe

The temperature measurement range is -100℃~200℃, and the probe adopts high-sensitivity temperature measuring elements, which has high measurement accuracy and strong anti-interference ability. It is widely used in ultra-low temperature refrigerators, freezer warehouses and other environmental temperature Measurement.

Ultra-high temperature probe

The temperature measurement range is 0℃~300℃, the probe adopts high-sensitivity temperature measuring element, which has high measurement accuracy and strong anti-interference ability. It is widely used in oven, tobacco, steel heat treatment Wait for the measurement of ambient temperature.

Second, temperature and humidity probes

There are many types of temperature and humidity probes, and the following types are commonly used in the industry: hardcover probes, waterproof probes, high-sensitivity probes, high-temperature probes, metal probes, quarter-pipe threaded probes.

Hardcover probe

The hardcover probe adopts a hollow shell design, which greatly improves the response sensitivity while preventing the internal sensor from colliding. The disadvantage is that it is waterproof and not dustproof, so everyone should pay attention when choosing.

Waterproof probe

The outer part of the waterproof probe is made of PE material, which is waterproof, dustproof and breathable. Water molecules can enter the sheath, but water droplets cannot enter the probe due to surface tension, so the humidity can be measured At the same time prevent water droplets from entering. This probe is widely used in environments such as soil, outdoor rain, and high-humidity greenhouses.

High-sensitivity probe

This high-sensitivity probe has double waterproof treatment on the whole, completely preventing condensation damage, responsive, waterproof and not dustproof, suitable for a variety of occasions.

High temperature probe

The outer sheath of the high temperature probe is made of sintered copper particles, equipped with high temperature cables, which is waterproof and durable, and is suitable for occasions where the measurement temperature is higher than 80°C.

Metal probe

The metal probe is made of sintered copper particles. It has the characteristics of air permeability and high temperature resistance. It is dustproof but not waterproof. It is suitable for occasions with high dust but high sensitivity.

Quad-pipe thread probe

The probe adopts standard quarter-pipe thread, which is suitable for measuring the temperature and humidity inside the pipe.

This is the end of the introduction about the single temperature probe and the temperature and humidity probe. I hope that through this article, you can have a deeper understanding of the temperature and humidity probe, and you can accurately choose the product that suits you when choosing measurement equipment. .
