1 Acceleration Transducers

2 Using a foil, sputter or semiconductor strain gage as the sensing element, KYOWA acceleration transducers convert the acceleration of a running vehicle or the vibration of a car body or machinery into minute voltage to enable accurate measurement of acceleration or vibration with a measuring instrument. Each model is compact and lightweight, and ensures superior static and dynamic characteristics. Various rated capacities cover a wide scope of applications. In addition, triaxial models are available for simultaneous detection of accelerations in three directions: X, Y and Z. Compact and lightweight design results in minimal effects on the vibration mode of the measuring object to which the transducer is mounted. Wide frequency response range enables faithful detection of impact-initiated acceleration. Fatigue life is million times or more. Triaxial models deliver minimal interference between axes. Installation and Removal Install the acceleration transducer aligning the sensitive axis with the acceleration measuring direction. The sensitive axis (+ ) is labelled on the transducer. The polarity of transducer output is positive if the transducer is installed with the + directed to the center of the earth (the gravitational acceleration). Depending on the model or application, the transducer is mounted to the measuring object using CC-33A adhesive, bolts or the mount base. For correct operation, mount the transducer according to the instruction manual. When removing, take sufficient care not to damage the transducer by applying excessive impact or force. Acceleration output ratio vs. frequency differs depending on mounting methods as follows: Acceleration output ratio(%) Acceleration output ratio(%) Measurement of acceleration in vertical direction [measuring range in the up direction is narrower by m/s 2 (1 G).] Frequency (Hz) 2 Frequency (Hz) Measurement of acceleration in horizontal direction 3 3 Screw or bolts CC-33A adhesive Overload Considerations Generally, the magnitude of acceleration is difficult to grasp by human perception. If the transducer is dropped on the floor, it may easily sense acceleration exceeding 9807 m/s 2 (00 G) depending on the material of the floor. If a small-capacity acceleration transducer receives an acceleration times larger than the rated capacity, the initial voltage unbalance changes outstandingly, thereby making the transducer unusable due to disconnection of the gage, etc. Thus, the acceleration transducer must be handled carefully. Temperature Effects To ensure flat frequency response characteristics, some models of acceleration transducers have oil sealed inside. The viscosity of the oil is adjusted to make the frequency response flat at 23 C. Changes in viscosity due to temperature changes affect the frequency response and phase characteristics. Though a silicone oil of which the viscosity hardly changes is adopted, the frequency response characteristics of the transducer are affected by temperatures as shown in the figure below. Thus, for accurate measurement in a frequency zone exceeding one-tenth the stated frequency response range, the temperature of the transducer should be kept around 23 C. Output sensitivity (%) 0 +% % 0 AS-50HB 13 C 2 C C 33 C Frequency (Hz) Temperatures vs. Frequency Response (in the case of AS-50HB of which the frequency response range is DC to 1.5 khz) Principle of As the basic configuration shows below, acceleration initiates inertia force to the weight and deforms the leaf spring. The strain gage adhered to the leaf spring detects the displacement of the leaf spring as a strain quantity proportional to the acceleration. The strain gage signal is amplified to enable acceleration measurement. An advantageous feature of this configuration is to enable the transducer to respond to static acceleration at DC.

11 Servo ASQ -CA/ASQ -CB Different from conventional strain gage acceleration transducers, the ASQ series have a servomechanism which ensures precise measurement of low levels of vibration with high sensitivity. A dedicated signal conditioner, the VAQ, is available for stable and reliable acceleration measurement. ASQ transducers can be used for measurement of vibrations generated by running vehicles, earthquakes or wind in structures or the ground as well as for measurement of general vibrations occurring at low frequencies.

The displacement sensor detects the displacement quantity and sends via the servoamplifier the signal to the drive coil which is fixed to the weight support. When the signal current flows to the drive coil placed in a magnetic field generated by the permanent magnet, the electromagnetic force of the coil returns the weight to the original position. Since the current is proportional to the applied acceleration, a proportional voltage to the acceleration is output from both ends of the resistor inserted in the current loop.
