Temperature and humidity transmitter and dew point transmitter are both instruments used to measure the temperature and humidity value in the environment, many users will also confuse the two transmitters, today I will take you to learn more about the difference between humidity transmitter and dew point transmitter. A temperature and humidity transmitter is an instrument equipped with moisture and heat sensitive elements to measure temperature and humidity. The temperature and humidity transmitter mostly uses the temperature and humidity integrated probe as the temperature measurement element, collects the temperature and humidity signal, and converts it into a current signal or voltage signal output with a linear relationship with temperature and humidity after being processed by voltage stabilization filtering, operation amplification, nonlinear correction, V/I conversion, constant current and reverse protection circuits, and can also be directly output through the main control chip for RS485 and other interfaces. Temperature and humidity transmitters are widely used in indoor environments such as offices, laboratories, building automation, ventilation ducts, heating and air conditioning systems, constant temperature and humidity controllers, control boxes and other equipment for temperature and humidity detection. A dew point transmitter is the temperature at which air is cooled to saturation without changing water vapor content and air pressure. Figuratively speaking, the temperature at which the water vapor in the air turns into 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 ship hold or container, moisture forms on the metal surfaces 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 occasions of the dew point transmitter are generally 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 technician to answer your questions.
