The Dytran 5334 is a high temperature hybrid vibration monitoring system, consisting of a charge mode accelerometer and in-line miniature differential charge amplifier operating from a constant current 2-wire (IEPE) power unit, permanently joined together as a single unit with an interconnecting integral hardline cable.
The unique configuration of the Dytran model 5334 is known as a hybrid system because it combines both IEPE and charge mode piezoelectric technologies into a single operating unit. The accelerometer is connected to the input of the charge amplifier via an 18-inch long hardline cable (SiO2 insulated) which is unaffected by high temperatures at the point of measurement.
The model 5334 features a case isolated design to avoid EMI/ground loop interference, with hermetic sealing for reliable operation in high humidity and dirty environments. Units offer an industry standard tri-bolt mount, stainless steel construction, and incorporate the use of ultra high temperature piezoelectric crystals in compression mode for extremely stable operation at temperatures up to +900°F (+482°C).
