In our chemical plant, corrosion at the connection terminals causes unpredictable driff in the RTD measurements. We clean and recalibrate regularly but labor and off-spe product costs are no longer acceptable.
Replace the old 3-wire RTDs with 4- wire sensors and useany of our family of temperature Transmitters. Each accepts and input from a 4- wire RTD andtogethertotally compensatefor the effects of terminal corrosion. A complete replacement assembly of transmitter & sensor cn be factory calibrated for optimal performance.
