Dytran Instruments has just released a new ultra high temperature accelerometer. Model 3218C is a charge mode accelerometer designed to measure vibration of surfaces at temperatures up to +900°F. This accelerometer utilizes an ultra stable crystal material in its self-generating seismic element.

Model 3218C is packaged in a hermetically sealed stainless steel housing, has a sensitivity of 1.6 pC/g and exhibits extreme stability over a wide temperature range. It features a two-foot integral hard line cable assembly, with a ceramic-to-metal sealed connector.

The 3218C is installed by use of three factory supplied 8-32 1/2 inch long socket head cap screws. The mounting screws thread into 3 matching threaded holes which must be provided in the mounting surface.

Model 3218C may be used with various differential charge amplifiers of the vibration type (as opposed to the DC coupled electrostatic types). Dytran recommends the in-line charge amplifier 4707 series for use with the 3218C. This inexpensive charge amplifier adapts the 3218C for use with any IEPE (constant current type) power unit.
