IMI Sensors: A PCB Piezotronics Division High Temperature ICP® Accelerometers Survive in higher temperature environments than competitors’ IEPE sensors Highlights n Capable of withstanding continuous temperatures of 325 °F (162 °C) without decay in performance, higher than any other IEPE accelerometer in the industry. Monitor machinery vibration in high temperature applications without the need for external charge amplifiers and/or other electronics. Shear mode element to withstand thermal transients and base bending. Hermetically-welded stainless steel housing to stand up to use in harsh environments. Multiple versions to satisfy a wide variety of application requirements. Top or side exit options available for flexibility in cable orientation. IMI Sensors is the industry leader in high temperature ICP® accelerometers. Our high temperature accelerometers with internal electronics can withstand a higher temperature environment than any other design on the market today. Often used by predictive maintenance departments, these accelerometers provide critical machinery data that prevents failures and reduces downtime. Quartz or ceramic element options available for environments with or without large temperature fluctuations.
