S ub-miniature triaxial vibration transducer comprising three KONIC A/25/E inserts bonded orthogonally into a hard anodised aluminium housing.
The inserts are electrically insulated, individually and from the housing, thus
eliminating ground loop interference. The additional mechanical isolation implicit in the construction provides also near elimination
of strain induced error.
The spatial response of a structure to dynamic forcing may lead to erroneous single axis vibration or shock measurement, due to the
inherent directional property of the transducer. |
|
A generic range of lightweight, KONIC sensing element based vibration transducers offering a choice of integral stud or flat base adhesive
attachment, and each with side or top mounted connector.
All welded construction maximises temperature range, reliability, and sensitivity is approximately double that of competitive equivalent mass
products. Spurious strain induced error, either via the structure or signal cable, is negligible.
Adhesive mounted versions : Abrasive cleaning of the attachment face will reduce base thickness over time, sparing use of adhesive will aid longevity. |

The D.Electron 3-axial acceleromter has been designed to be the transducer of a motion control system capable of eliminating unwanted floxures and oscillations of a machine tool.
While the standard position transducer cannot measure the real tool-tip position, it could be the nearer transducer to the tip of the tool.
Novelty of the D.Electron 3-axial accelrometer is the possibility of being connected to any motion control system (not only D.Electron Z32 CNC): its output is coded as a standard encoder output.
The accelerometer has been designed for real-time applications, with extremely fast A/D conversion and maximum output delay below 1 mcro-second. |

Various Kistler accelerometers are suitable for use even at the extremes of the measurement range. Miniature models designed for minimal mass loading are still capable of generating a significant signal. Conversely, high sensitivity models are available for testing low amplitude motions down to a complete standstill.

DESCRIPTION
The Model 2422 triaxial accelerometer module combines three orthogonally mounted Model 1210 integrated accelerometers in an anodized aluminum case for measuring accelerations in commercial/industrial environments. It is tailored for zero to medium frequency instrumentation applications. Each of the three internal accelerometers contains a miniature, hermetically sealed, micromachined capacitive sense element and a custom integrated circuit sense amplifier. It is relatively insensitive to temperature changes and gradients and its frequency response includes DC.
• Rugged Anodized Aluminum Case
• No External Reference Voltage Required

| Wilcoxon Research manufactures a variety of triaxial sensors which consist of three sensing elements within a single housing. These transducers allow for the acquisition of multi-directional data at a single mounting location. Proponents of multi-axial sensors cite the increase speed of data collection, its inherently consistent readings and reduction in wiring for permanent installations. |

Lightweight triaxial vibration transducer comprising three KONIC all welded inserts, each with hybrid QVC, bonded orthogonally into a hard anodised aluminium housing. The inserts are electrically insulated, individually
and from the housing, thus eliminating ground loop interference. Low impedance O/P provides a high degree of noise immunity (80dB
improvement vs. equiv. charge source device @ 50Hz) and allows use with low cost coaxialcable.
The additional mechanical isolation implicit in the construction provides also near elimination of strain induced error. All the 3x10/32 Microdot connectors are exiting in the same direction.
The spatial response of a structure to dynamic forcing, may lead to erroneous single axis vibration or shock measurement due to the
inherent directional property of the transducer. |

Highest sensitivity multiple shear plate vibration transducer, intended for micro g level measurement. Virtual immunity to strain input side effects provides guarantee of low frequency measurement integrity. System noise
level of 10-2pC is equivalent to 1mg. With bandwidth restricted to 2kHz, 1 octave below resonance, noise floor should be significantly below this.
Noise level vs. upper corner frequency for the CA/04/N charge amplifier, A/800 source and nominal l0Mtr. cable is shown in Fig.1. Bear in mind that charge amplifier noise increases as a function of input capacitance - noise
assessment should be made with the charge amplifier input correctly terminated.
The transducer adds mass at its point of attachment to a structure, thus imposes a transparency constraint above which data corruption will be excessive. |

The most popular and environmentally friendly motion and vibration sensors are the AU2400 and AU2401 series. Being gold plated, they have a superior contact surface.
A new version of motion and vibration sensors is the AG2400 and AG2401. For these the gold plating has been replaced by silver for less critical applications in order to reduce cost.
The motion or vibration sensors are %u201Cchange of state%u201D sensors; that is the contacts may be open or closed in any position but upon movement or vibration the contacts will change state intermittently.
The contact capacity is 24 Vac/dc, at 0.20 amps max and 5VA max.
Several different electrode configurations exist for hole and surface mounting.
