4-20mA Temperature and Humidity Transmitter - China Manufacturers, Factory, Suppliers

Temperature and humidity transmitters are essential to almost any process control application that requires temperature and humidity monitoring. These transmitters receive a signal from Humidity sensitive, convert that signal to a stronger, more stable signal, scale the new signal to a preset range, and send the new signal to other instruments - such as panel meters, controllers, or loggers - that will use the signal to activate another part of the process or to display or record the measurement results.

Temperature and humidity transmitters often use a 4-20mA signal. Analog current loops, such as 4-20mA, offer simplicity and excellent immunity to electrical interference and signal loss from long cable runs. These benefits make current loops - especially 4-20mA current loops - the de facto industry standard for electrical signals in process control applications.
