Tech Tip Tuesday – Are Your Chiller System Sensors Accurate?

If you haven’t calibrated them regularly, the answer is probably NO! And your data is only as good as the sensors.

Here’s what the experts say to look for:

  • Temperature sensors–accurate to 1/10 °F
  • Delta pressure– accurate to 1/10 psig
  • Water flows–accurate to within 1%
  • Refrigerant pressures–accurate to within 0.5%
