Both humidity and temperature transmitters and dew point transmitters are instruments used to measure temperature and humidity values in the environment. Many users will also confuse the two transmitters, and today’s technicians will take you to learn more about the difference between humidity transmitters and dew point transmitters.
A humidity and temperature transmitter is an instrument equipped with moisture and heat sensitive elements to measure temperature and humidity. Temperature and humidity transmitter mostly uses temperature and humidity integrated probe as temperature measurement element, the temperature and humidity signal is collected, after voltage stabilization, filtering, operation amplification, nonlinear correction, V/I conversion, constant current and reverse protection and other circuit processing, converted into a linear relationship with temperature and humidity current signal or voltage signal output, can also be directly through the main control chip RS485 and other interface output. Temperature and humidity transmitters are widely used in indoor environments such as offices, laboratories, building automation, ventilation ducts, heating air conditioning systems, constant temperature and humidity controllers, control boxes and other equipment temperature and humidity detection.
The dew point transmitter refers to the temperature at which the air is cooled to saturation without changing the water vapor content and air pressure. Figuratively speaking, the temperature at which the water vapor in the air changes to dew is called the dew point temperature. If the temperature of the outside air is lower than the internal temperature of an enclosed space such as a cabin or container, moisture forms on the metal surface inside the ship or container. On the other hand, if the temperature of the outside air is higher than the temperature inside the ship or container, moisture forms directly on the surface of the cargo. In some cases, it is necessary to ventilate the cabin to change the dew point temperature to avoid condensation. At this time, it is necessary to install a dew point sensor, and the application of dew point transmitters is generally used in container ships, compressed air, natural gas and other industries.
Through the above explanation, we have a general understanding of temperature and humidity transmitters and dew point transmitters, if you have more questions, you can consult the star instrument technicians to answer your questions.
