Choosing & Installing Best Temperature Monitoring Device and How it Works
A wrong or doubtful Temperature Monitoring Device can have very costly consequences. The transmitter is directly linked to the thermocouple, or RTD leads, converting the input signal to an output signal with a range of 4 to 20 mA, 0 to 10 Vdc, or a digital output signal like RS232, RS485. This is sent via a twisted pair wire wherever it has to be shown or recorded. There are many different types and levels of sophistication for temperature transmitters, ranging from small, DIN rail-mountable units to programmable, "smart" devices with diagnostic capabilities. The Benefits of Temperature Transmitters Direct connecting of Temperature Monitoring devices to data logging or display equipment was customary in the past. Engineers are starting to understand the advantages of employing temperature transmitters, though. • Less costly wiring. Thermocouple extension cables are typically more expensive and more delicate than regular twisted pair cables since they are typic
