Wilcoxon Research offers three options for applications in which temperatures are above the normal operating range of industrial accelerometers, greater than 250ºF (120ºC). The FireFET™ series, models 793-6 and 797-6, is designed for continuous operation up to 302ºF (150ºC). These sensors are typically used where extra temperature protection is needed, such as the industrial dryer section of a paper machine.
If an installation is greater than 302ºF, a special type of accelerometer system is necessary. The 376/CC701HT system consists of three parts: sensing accelerometer (376), charge industrial converter (CC701HT) and connecting cable. Using this arrangement, the temperature-sensitive professional amplifier (charge converter) is removed from the sensor and placed within a separate component outside the intense heat. One end of the charge converter will be connected to the sensor via the supplied cable and the other will be available to connect to analysis or acquisition equipment. As with all "charge mode" sensors, care must be taken to secure the connecting cable when taking data. Movement of this cable may induce false signals (triboloectric effect).
