TEMPERATURE MEASUREMENT AND CONTROL CABLES
General information; In our day, heat control systems is one of the most important topic of control technologies.
Heat and Temperature are important parameters that can affect physical features. It is one of the most important factors in production processes. Thus, it is essential to measure temperatures with high precision. There are several methods to measure heat/temperature. In these methods, thermocouple sensor is the most commonly used equipment.
PT10 - PT100 - PTC - NTC sensors are some other utilities that can be required other than thermocouples under different circumstances.
The main concern of our firm is cables that link up the sensors and measurement devices. In our website, you can find technical details about these cables. Users can make their cable choices according to measurement sensors(TC-PT100-PTC-NTC) and working environment temperature by utilizing from this website. Correct cable choice is one of the most important issues of heat control for precise measurements. These cables, that we are producing, are listed under different tables related to their types and insulation classes.
THERMOCOUPLE CABLES
General Informations; Thermocouple is a temperature measurement componenet that is created by welding two different alloy wires. The welding point is named as hot junction and the other two lead is called as cold junctions. The cold junction is also called as reference point.
A thermocouple produces a temperature-dependant voltage as a result of the thermoelectric effect, and this voltage can be interpreted to measure temperature.(EMF)
Since, the thermoelectric effect occurs as a result of potential difference between cold and hot junction, the ambient temperature of cold junction is very important. On the condition that temperature of hot junction is fixed, if the temperature of cold junction changes, different temperature values will be read from the measurement device. Therefore, in order to provide standardisation for thermocouple cables, milivolt values (equivelant of measured temperature) are obtained by fixing the temperature at 0°C for cold junction.
What is a Thermocouple Cable?
Yet, thermocouple is made out of two metal or alloy wire, it can not be used as bare wire. Thermocouples are used in certain special sheath in order to protect from several mechanic impact by considering physical and chemical features. Covering these bare wires by usin different insulation material as required creates thermocouple cables. Thermocouple cables have many different types which are classed as their wire and insulation types. These varieties are placed on main products table. Products on the table can be manufactured as ordered as multiple pers or multiple cores.
EXTENSION AND COMPENSATION CABLES
General Informations; Connection and communication between thermocouples and devices are provided with cables that are compatible with thermocouple conductors. These cables are called as extension and compensation cables.
Extension Cables; Wires(conductors) of extension cable are used same as thermocouple's alloys conductor, and they are stated with letter X at the end like JX,KX etc.
Compensation Cables; Conductors of these cables does not need to be same as thermocouple's alloy wire, however it has to be made out of conductors that have the capacity of carrying milivoltages(EMF). These cables are symbolized with C letter at the end of thermocouple code like KCA, KCB etc.
PT100 CABLES - RESISTANCE THERMOMETER CABLES
Connections between device and resistance thermometers are made by certain standardised cables. Resistance thermometer is a resistor that measured values vary with the heat. Therefore, resistance value of the cable will be added to circuit as factor that can affect the temperature measurement. In other words, throughout the cable production process, some important issues come into the topic related to cable length. Resistance value of the cable should not affect the resistance value of the resistance thermometer more than determined rates that are given in standards. Otherwise, temperature values have to be read perfectly accurate.
Another issue about the cables that are connecting the resistance thermometer and the device, is cable's insulation class. Temperature of the cable at the connection point to R/T and cable's ambient temperature are very essential. Cables will be chosen according to determined temperatures and by taking insulation classes into consideration. Basically, there are two issues about cable choice. These are cable section and cable insulation. Choices have to be made by utilizing IEC 584 Standard and DIN 43713 norms.Our products are conforming the standards.
