Low Cost Averaging RTDs
Low cost averaging RTDs sense the temperature of air streams in ducts and plenums. This sensor includes a junction box with gasket to prevent leakage and vibration noise.
These thermometers have a continuous element to sense true average temperature along their entire length. They provide accurate composite readings in locations where air may be stratified into hot and cold layers.
Rigid averaging sensors have a brass case. Bendable models have aluminum sheaths (Copper on special order) formable to a radius of 4". Bendable sensors can crisscross ducts to averaging temperatures in two dimensions.
- Temperature range: -45.5 to 135°C (-50 to 275°F)
- Gasket: 100°C (212°F)
- Leadwire: 22AWG, Teflon insulated, 8" long
- Sheath diameter: 0.188" OD
