3-21084-4 is a 4-wire circuit electric temperature transmitter that can measure both the temperature and the hot resistance of the rods. This component has a wide range of applications and plays an important role in the manufacturing and industrial industries. In this article, we will look at the field of application and the working principle of 3-21084-4.

The 3-21084-4 is commonly used in industrial instrumentation, such as furnace instrumentation, petrochemical instrumentation, and diesel generating plant instrumentation. It can also be used in boilers, steam turbines, compressors, and cooling systems. The 3-21084-4 is designed to measure temperatures of -50 ° C to +600 ° C. It is also able to measure temperatures in hazardous areas where there are combustible gases or dust.

In addition to its industrial uses, the 3-21084-4 has also found applications in the commercial and domestic sectors. It can be used in food processing plants for monitoring the temperatures of cooking and baking ovens. The device can also be used to monitor the temperatures in residential and commercial refrigeration systems.

The 3-21084-4 has a wide range of features that make it a versatile and reliable instrument. It is designed to be easy to install and configure for temperature measurement. The device is also very reliable and accurate in its measurements. It has a wide temperature measurement range, with an accuracy of 0.025% or 2.5 mV/°C.

The 3-21084-4 works by measuring the voltage drop across a Wheatstone bridge between a pair of temperature probes. The bridge is supplied with a 4-20mA output signal and is connected to the transmitter. The bridge outputs the voltage drop across the two probes, which the transmitter uses to calculate the temperature. The temperature is then displayed on the transmitter\'s output screen. The device also has built-in compensation circuitry to reduce errors caused by external factors, such as large temperature fluctuations and electrical noise.

The 3-21084-4 is a highly versatile and reliable temperature transmitter. It can be used in a wide range of industrial and commercial applications and is designed for easy installation and configuration. Its accuracy and wide temperature range make it suitable for monitoring temperatures in hazardous areas, such as in combustible gases or dust. Its compensation circuitry helps to reduce errors caused by external factors and ensures accurate measurements.
