It is important to monitor the temperature in separate areas in a device or system, and give a common warning whenever these areas reach their respective limits.
Deploying an electronic device for each area will be costly. Instead, it is desirable to have an electronic device that intends to detect temperatures in specific areas, compares pre-determined limits, and announces a common alarm. Temperature scanners are used for such purposes.
What is a temperature controller?
A temperature controller is a device that measures more than one or more degrees of multi-channel temperature. This scanner is designed to continuously monitor the temperature and give an alarm when crossing the border.
In fact, it is a multi-channel tool that monitors and displays signals from each channel to the last, then moves to the first channel and repeats the process.
Temperature controllers have alarm / control relay input, serial port for connection to SCADA / DCS / PLC.
The temperature controller is a microprocessor-based device that detects the thermocouple / RTD form for each input. It is possible to control each channel manually or automatically and display active areas.
The instrument is programmable for all types of J, K, T or E thermocouple inputs, ° C or Fahrenheit, and the control speed is between 2 and 60 seconds.
