OVERVIEW

Basic Details: 3HNA023093-001 Thermocouple/mV Input Module

The 3HNA023093-001 Thermocouple/Millivolt Input Module is a module for temperature measurement that senses temperature changes via a thermocouple or millivolt signal input.

A thermocouple is a temperature sensor that uses the thermoelectric effect between two dissimilar metals to measure temperature. 

When the temperature changes, the thermocouple produces a voltage signal proportional to the change in temperature.

A millivolt input module is a module capable of receiving millivolt signals that can be converted to digital signals for subsequent processing and display.

3HNA023093-001 Thermocouple/millivolt input modules typically have the following functions:

Temperature measurement: with a thermocouple or millivolt signal input, the module is able to sense temperature changes and convert them to a digital signal output.

Signal Processing: Modules may have signal processing functions such as amplification, filtering, digitisation, etc. to improve measurement accuracy and stability.

Output Interface: Modules usually have an output interface to output digital signals to other devices or systems for display, control or recording.

Please note that the above functions may vary depending on the specific model and application requirements.

Therefore, when using the 3HNA023093-001 Thermocouple/Millivolt Input Module, it is recommended that you refer to its official documentation or contact the manufacturer for accurate and detailed functional information.

The 3HNA023093-001 Thermocouple/Millivolt Input Module works as follows:

A thermocouple is made by connecting one end of two different metallic materials together and connecting the other end to one of the terminals above, and then using a voltmeter to measure the voltage at the ends of the terminals, which can usually be measured as a small voltage value.

If the two wires are made of different materials, such as a copper wire and a wire, because the thermal conductivity effect of the two wires is not the same, and the temperature of the cold end of the two wires is not the same, which means that the number of free electrons is not the same, at this time, the voltmeter can measure the voltage value.

The 3HNA023093-001 thermocouple/millivolt input module is an ABB branded product for temperature measurement and conversion.

It measures the temperature directly and converts the temperature signal to a thermodynamic force signal, which is then converted to the temperature of the measured medium by means of an electrical instrument (secondary instrument).
