Thermal switches cut off the electric motor from the source in case of short circuit or overload. Disconnected and connected.\r\n\r\n**[Click here to view Chinat products.](https://www.automation24.ir/product/list/search/?manufacturer_id=83&pageItems=120)** \r\n\r\n### Working principles of thermal switch\r\n\r\nThe working basis of this key is based on the difference in the longitudinal expansion coefficient of two metals, which means that due to the current passing through the non-metal, the two metals are heated and their length increases. Since the longitudinal expansion coefficient of one of the metals is higher than the other. Two metals are bent together towards the metal that has a lower coefficient of longitudinal expansion. As a result, the current path of the contacts is opened and the circuit is cut off. In addition to thermal switches, auxiliary equipment, including auxiliary contacts, fault contacts, shunt coils and undervoltage coils are used. Due to the fact that these keys have the capability of short circuit protection, as a result, they have different short circuit power depending on the working current range.\r\n\r\n \r\n\r\n \r\n### Current range of chint thermal switch\r\n\r\n1 ———1.6 amp\r\n \r\n1.6——-2.5 amps\r\n \r\n2.5——---4 amps\r\n\r\n4 ———--6 amps\r\n\r\n6 ———-10 amps\r\n\r\n9 ———-13 amps\r\n\r\n11——--17 amps\r\n\r\n14———22 amps\r\n\r\n18———26 amps\r\n\r\n22———32 amps

Among these sensors, we can mention thermocouples and RTDs, which have the ability to sense the temperature value. Now, in order for the user to be able to read the temperature of this sensor, he can use thermostats. In fact, one of the most important features of the thermostat is the ability to display the temperature value of the sensor.\r\n\r\nThermostat is a combination of the Greek words Thermo (heat) and statos (stop and stay). Therefore, from the integration of these two words, we understand that the thermostat is a device that maintains the heat at the set point.\r\n\r\nIn addition to displaying the temperature value, thermostats have other functions. Thermostats can keep the temperature of an environment constant. Some thermostats can have more than one temperature sensor connected to them to display the temperature. PLCs also have the ability to read and display the temperature value. But since it may not be economically justified to use PLCs in many cases, thermostats can be used. Some thermostats also have the ability to be networked in industrial processes. They can read multiple alarms from them. Also, thermostats have the ability to become PID, which makes this important feature increase the use of this equipment in burners.\r\n\r\n## Main features:\r\n● Advanced PID control algorithm with 100 ms sampling speed\r\n\r\n● Ability to select output between relay or SSR\r\n\r\n● Built in small size with large screen for better viewing\r\n\r\n● Has 1 LED set to display temperature\r\n\r\n● The possibility of choosing the input voltage of 24-24 VDC\r\n\r\nThermostats have various working modes, for example, you can mention cold and heat mode in thermostats. Control mode is also defined in the thermostat. In fact, the output of the thermostat can be defined in different modes, the output of the thermostat (that is, the methods of reaching the temperature set by the user) can be ON/OFF, in this case the output of the thermostat can act as a relay or SSR. But there is another widely used mode, which is called PID mode. In the PID mode, the control should only be selected as SSR due to the large number of connections and disconnections.\r\n\r\nON/OFF mode: a - relay b - SSR \r\n\r\nPID mode: SSR mode only\r\n\r\nAlso, some thermostats have the ability to store information related to temperature, which expands the use of this equipment.\r\n\r\n\r\n**[Click here to view Atonix products.](https://www.automation24.ir/product/list/search/?manufacturer_id=3&pageItems=120)**\r\n\r\n## Features of the thermostat:\r\n1.

This collection prepares and equips slim series PLCs for all types of applications.\r\n\r\n\r\n### PLC:\r\n\r\nToday, with the advancement of science and technology and going towards reducing costs, there have been many changes in electrical science. The use of complex circuits, which all used a lot of wiring and caused many problems, led to the emergence of new technologies. Meanwhile, PLCs have created a good space in the industry.\r\n\r\nPLC stands for Programmable Logic Controller. The use of PLC has created a suitable environment for reducing costs, automating equipment, and reducing failures resulting from excessive wiring.\r\n\r\nThe function of PLC used to be relay command circuits, whose use has become obsolete in new industrial environments. With the use of PLC, changes in the process of machine operation are made easily. Because it is no longer necessary to change the wiring and control hardware, and it is enough to write a few lines of program and send it to the PLC to realize the desired control.\r\n\r\n\r\n\r\n\r\n**[Click here to view Delta products.](https://www.automation24.ir/product/list/search?keywords=&in_description=1&category_id=0&inc_subs=1&manufacturer_id=5&pfrom=&pto=)**\r\n\r\n\r\n\r\n## Features of PLCs:\r\n\r\nThey have a modular structure, parts of which can be replaced easily.\r\nThe possibility of changing the program without changing the wiring and reaching the desired output.\r\nPossibility of remote control.\r\n\r\n\r\n## Components of PLC:\r\nPower supply unit\r\nCPU central processing unit\r\nmemory\r\nInput modules\r\nOutput modules\r\nSignal transformation modules\r\nProcessor communication modules\r\nInterface module\r\nThe body of the shelves

The nominal detection distance of the capacitive sensor is different depending on the type of part it detects.\r\n\r\n\r\n\r\nFor example, if a capacitive sensor detects a metal piece from a distance of 20 mm, the same sensor will detect a glass piece at a distance of 10 mm. In the above table, the correction factor of some parts regarding the performance of capacitive sensors is mentioned\r\n\r\nAtonix capacitive sensors are made in cylindrical form and in two types of AC two wires and DC three wires.
