Dytran Instruments, a manufacturer of transducers, and DC MEMS and piezoelectric accelerometers, has developed a new compact high temperature accelerometer model 3316C, which is equipped with a charge mode element installed in a hermetically sealed, compact Inconel housing.
Dytran Instruments Introduces 3316C Piezoelectric Accelerometer for High Temperature Applications
The Dytran’s 3316C acceleration sensor, developed with distinct Dytran patented features using latest planar shear technology, is capable of functioning at high temperatures of greater than 900°F. The acceleration sensing system includes a silver window on the top cover of the Inconel housing, which ensures oxygen access to the crystals at increased temperatures thereby maintaining the system’s hermetic sealing.
The newly introduced Dytran’s 3316C accelerometer is compact having a height of about 0.36 in. and weight of 5 gm., which makes it to be suitably used in a smallest span of area. The 3316C accelerometer includes 5-40 tapped hole and 10-32 radial connector. This acceleration sensing system offers sensitivity from 1 to 2 pC/g and ensures 10,000 Hz upper frequency response. Since these accelerometers ensure high durability, wide range of functioning temperatures and less weight, the Dytran’s 3316C can be suitably used in environments of increased temperature including exhaust system analysis, automotive vibration studies, environmental stress screening (ESS) and engine vibration analysis.
Since the Dytran’s 3316C accelerometers is provided with a non-isolated ground connection to the housing, there is an increased occurrence of EMI/ground loop interference at very high temperatures. To avoid such interference, it is advisable to employ either the single (6998) or triaxial (6989) isolated mounting blocks for isolating the 3316C sensor from the mounting surface. The additional accessories required for using the Dytran’s 3316c accelerometers include model 4752B in-line charge amplifier and model 6946A or 6979A hardline cable assembly.
