| Test and measurement supplier of accelerometers are generally characterized by smaller size than industrial units and typically use a 10-32 co-axial connector manufacturers to connect to measurement equipment. While they are sometimes used in industrial environments for machinery vibration collection, they are usually used in laboratories and similar environments. Modal and structural testing are the typical applications for test and measurement sensors. |

Acceleration sensors detect vibrations, seismic activity, inclination in static systems and linear acceleration in machines, buildings and movable goods. On the basis of a micro-electromechanic system (MEMS) this product group includes sensors with analog current- or voltage output, direct BUS-connection or adjustable switching thresholds. The modular design of the housing allows the use of JPT- or M12-connectors as well as fixed cable options as needed.

| The basis for the QG sensors is a micro machined capacitive sensing element in silicium (MEMS). Despite the high accuracy this element has a very high shock resistance; a sensor with a 1G full scale sensitivity can withstand shocks up 20.000G ! The capacitance levels are transformed with an integrated professional amplifier to analogue voltage levels. A range of I/O configurations are possible with the modular setup of complementary circuits inside the sensor. All QG sensors benefit from the robust QUADRO® (PDF) housing. |

High output together with minimal susceptibility to strain induced error
extends the measurement range of the A/21 down to the 10-5g, 10-1Hz region.
The A/21 application area thus includes low level, low frequency dynamic analysis as occurs in the civil and marine engineering fields.
The KONIC sensing element, all welded construction, and total absence of epoxies and soldered connections maximises sensitivity /mass ratio (3pC/gm), reliability, and operating temperature. |
|
Ultra high output, multiple shear plate vibration transducer. Shear plate
construction provides near total isolation from mechanical inputs other than acceleration, thus safeguarding measurement integrity in applications where vibration is accompanied by high dynamic strain levels.
Generalising, these conditions are prevalent where modal frequencies are low, and are thus associated with vibration surveys of large structures.
Transducers exhibiting significant strain response may operate more akin to strain gauges at low frequency excitation and their use is thus to be discouraged ! System noise level of 10-3pC is equivalent to 1µg.
This should be realizable with bandwidth restricted to 1kHz. |
|
This ultra small vibration transducer (0.25 gram!)provides
virtual transparency applied to lightweight
structures, allied to relative freedom from strain
induced error. The reliability and performance
criteria applied to our transducers generally,
welded electrical connections and case professional seal, are
fully implemented in the construction of the
A/28/E.
Signal outlet is via a
surface contact socket.
A 0.8mm dia. softline cable is available
specifically for the A/28/E. |
|
Micro-miniature triaxial vibration transducer comprising three shear plate. A/28/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.
In cases where this is deemed to be a problem, an orthogonal three axis measurement, allowing computation of absolute value and direction offers a solution. |
|
Sub-miniature, all welded, KONIC sensing element based vibration transducer. The low mass of the A/25/E renders it transparent in the vast majority of lightweight structure vibration measurement applications.
The A/25/E is professional adhesive mounted. A detachment tool is provided to shear adhesive joints. Shock removal is to be avoided as being deletorious to
the integrity of the transducer.
Abrasive cleaning of the attachment face will reduce base thickness over time, sparing use of adhesive will aid longevity. Signal outlet is via a surface contact socket. Mating connector manufacturer preload torque should be 7cNm, the locknut tightened to 12cNm for signal integrity to 10,000g. Insufficient preload may result in intermittent signal loss. |

isolation discs to minimise ground loop
interference, whilst the top entry connector specification
version (A/124/TS) is also available with integral
mounting stud but without isolation. |

Include modal analysis of lightweight structures and shock measurement. Low frequency multi point modal measurements are subject to
individual phase/gain errors associated with the lower corner frequency of the QVC.
The ratiometric nature of modal analysis however reduces transfer function uncertainty to the associated lower corner frequency variations of individual QVCs. |
