High-temperature piezoelectric sensors are crucial in harsh environments. To effectively capture vibration signals, they require a high-temperature charge-mode sensor, a remote charge amplifier, and a durable cable. As temperature rises, insulation resistance drops; for example, model 3316M3 shifts from 100 Mega Ohms at room temperature to 250 Kilo Ohms at 1,000°F. This necessitates careful selection of the charge amplifier and cable for accurate data retrieval.
