    2020-8-17 · When it comes to cost, thermocouples are generally less expensive than RTD sensors, as most thermocouples cost between half to one third of an RTD. As mentioned however, thermocouples require regular adjustments and calibration, which in addition to the longer installation and setup times, adds to the long-term costs of the product.

  • Precision RTD & ThermocoupleThermometer - Omega

    Most thermocouples cost 2.5 to 3 times less than RTDs and the fact RTD installation is less expensive than thermocouple installation, the savings in installation costs are not enough to tip the balance. Besides, thermocouples are intended to be more tough and respond quicker to changes in temperature because of that same design.
