Averaging Resistance Temperature Detectors
Continuous Averaging RTD
The continuous averaging RTD probe measures the temperature over its entire length to provide a true average temperature measurement of the cross sectional area of large air ducts or other low temperature air averaging applications. The sensing element is contained within a bendable 3/16” O.D tube and its resistance output conforms to a 100 ohm platinum element with a 0.00385 temperature coefficient. Lengths up to 50 feet in copper and 20 feet in stainless steel can be supplied. Units can be provided with integrally mounted 4-20 mA transmitters. Maximum temperature rating is 100°C.
Flexible 5 & 10-PT Averaging RTD
The point averaging probe is used to measure the average cross-sectional temperature of large air ducts or low temperature ovens and drying kilns. The unit measures at 5 and 10 points specified along its length and averages these temperatures for a single output. The sensing elements are inside a 0.270” O.D flexible stainless steel armoured cable. An optional PVC covered cable is available for moisture protection. Resistance output conforms to a 100 ohm platinum element with a 0.00385 temperature coefficient. Units can be provided with integrally mounted 4-20 mA transmitters. Maximum temperature is 200°C (100°C with PVC Jacket).
Rigid 5 & 10-PT Averaging RTD
The point averaging probe is used to measure the average cross-sectional temperature of large air ducts or low temperature ovensand drying kilns. The unit measures at 5 or 10 points specified along its length and averages these temperatures for a single output. The sensing elements are inside a 0.250” O.D. stainless steel tube. Resistance output conforms to a 100 ohm platinum element with a .00385 temperature coefficient. Units can be provided with integrally mounted 4-20 mA transmitters. Maximum temperature is 200°C.
