Meggitt's Wilcoxon Research HT (high temperature) series of vibration sensors provides reliable, continuous output for condition monitoring applications where temperatures reach 150° C. The high performance sensors are field-tested with mean time before failure (MTBF) of 25 years. Extreme temperatures can cause sensor degradation and corrosion, requiring frequent replacement or calibration. To offset the effect of high temperatures on internal electronics, the durable internal components are rated at 200° C for consistent bias output voltage levels over the entire temperature range. Rugged housings and hermetic sealing protects against ground loops and RF interference, promoting long-term stability. Small casings enable easy installation on paper dryers, rollers, pumps, steam generators, and other machinery operating in high temperatures.
