RTD Meters

RTD Meters

  • Resistance Temperature Detectors (RTD)
RTD sensors measure temperature by measuring the change in electrical resistance across the metal wire. The resistance value is then measured and interpreted by a RTD thermometer, and displayed for a user to view. While RTD wire can be made of any metal, platinum is the metal of choice due to its excellent repeatability, stability and resistance to corrosion and chemicals.


Temperature Measurement Applications

Measuring and interpreting temperature has many MRO applications. Measurements throughout the plant can be done quickly and easily and without complex analysis. This information can then be stored electronically for later data trend analysis.

An electrical application is plant wiring. Anytime electrical current flows through a cable or connection, electrical resistance generates heat. Increased current flow through a cable generates more heat. If two similar sized cables have different temperatures, then the cable with the higher temperature carries the higher current. Resistance and heat build-up also occurs at loose or defective wiring connections.

Some typical applications for technicians and service personnel are:

Watching bearing temperatures to predict failure
Detecting motor overload
Finding defective transformers
Detecting loose and improper wiring connections
Checking electrical panels for hot spots
Measuring the surface of HVAC ductwork to reveal temperature variations, poor insulation and duct leakage
Diagnosing blown or plugged steam traps from a distance
Evaluating temperature differences between supply/return registers in a HVAC system
Checking for coil sweating on condensate lines in refrigeration systems
Checking the temperature of emergency relief valves
Diagnosing water leaks by measuring wallboard temperatures. Moist spots on walls will experience water evaporation and therefore will measure at a lower temperature
Testing furnace performance by checking the flue and supply grill temperatures
