FAQ

1. What is the lens material on your thermometers?
Most Winters thermometers will come with a glass lens. However, we also provide acrylic and polycarbonate lenses.

2. What types of thermometers do you carry?
Winters carries 5 types of thermometers: bi-metal, liquid-in-glass, remote reading (with C tube operation), RTD and solar digital. There are benefits and advantageous to each of these thermometers so it is important to know the environment and location for each application.

3. What are thermowells and do I need them?
Thermowells must be used on any application where the stem of the thermometer may be exposed to pressure, corrosive fluids or high velocity. Thermowells come standard with many of Winters’ thermometers. A thermowell is fitted/mounted directly into the process line and creates a closed system so that thermometers may be interchanged for calibration or repair without disturbing or closing down the process. Thermowells are available in brass or stainless steel. Other materials and flange options are available upon request.

4. An RTD and remote reading thermometer both measure temperature remotely. What are the differences between them?
The primary difference between these two products is the reading output: an RTD provides an electronic output signal to a display or controller which will read the signal to display the temperature. A remote reading thermometer operates manually by indicating the temperature as a result of expanding/compressing gases in its Bourdon C tube. An RTD is very accurate and provides stable operation over time, but is not suitable for high vibration or mechanical shock environments. A remote reading thermometer, however, is not subject to indicator error from ambient conditions, but is not as accurate as the RTD.
