Selecting the Proper Transducer

There are several important considerations when selecting a transducer to perform your measurements. The first decision that must be made is what type of transducer to use.
NOTE: The HVM100 has built-in ICP power supplies and charge amplifiers. This will allow the HVM100 to interface directly with ICP or charge transducers, and eliminates the need for external sig­nal conditioning.
There are two general categories of accelerometers, ICP and Charge.
®
•ICP
accelerometers are also called “Voltage Mode” or “Low impedance” and may be known by various other vendor trade names. ICP is PCB’s registered trademark which stands for “Integrated Circuit Piezoelectric” and identifies PCB sensors which incorporate built-in, signal conditioning electronics. The built-in electronics serve to convert the high impedance charge signal that is generated by the piezoelectric sensing element to a usable low impedance voltage signal which can be readily transmitted over ordinary 2 wire or coaxial cables to any voltage readout or recording device. The low impedance signal can be transmitted over long cable distances and used in dirty field or factory environments with little signal degradation.
®
Charge mode sensors output a high impedance, electrical charge signal that is generated by the piezoelectric sensing element. This signal is extremely sensitive to corruption from environmental influences. To conduct accurate measurements, it is necessary to condition this signal to a a low impedance voltage before it can be input to a readout or recording device. A charge amplifier or in-line charge converter is generally used for this purpose.
®
The final way to use the input of the HVM100 is through the direct input. This would require the use of some kind of external signal conditioning unit such as an external source of ICP power, or an external charge amplifier.
HVM100 Manual 1-5
Page 15
The next item to consider is the sensitivity of the transducer. The sensitivity of the accelerometer will depend on the application being performed. If the application is a high vibration level application, a low sensitivity should be selected. For low vibration level applications a high sensitivity accelerometer should be used.
NOTE: Transverse sensitivity is also something to be considered. Transverse sensitivity is defined as: The unwanted output signal of a motion sensor when subjected to motion perpendicular to the sensitive axis-usually expressed as a per­cent of the normal axis sensitivity. For example if you are using a tri-axial accelerometer and place an input signal on the Z axis, your X axis could also be reading a level even though there is really no x-axis signal present.
The resonant frequency of the transducer should also be considered. The resonant frequency is defined as the frequency at which the structure will readily vibrate. For accelerometers, there is one frequency where the accelerometer will vibrate much easier than at other frequencies. At this point, the reading will be very high, and could overload the input of the HVM100. However, for most of the recommended accelerometers, the resonant frequency is well above the upper limit of the HVM100, and will subsequently be masked out by the low pass filter on the HVM100. If the resonant frequency becomes an issue, it is recommended that an external mechanical filter be used.
Frequency range is the next thing to take into consideration. Most recommended accelerometers will have a frequency range sufficient for use with the HVM100. See the frequency response tables (appendix A) and graphs (appendix D) for more information on the HVM100’s frequency response.
The last thing to consider is temperature, humidity, and other physical agents, such as mounting surface, mass and environment. The mass of the accelerometer should ideally be no more that 1/50 of the mass of the object being measured. A ratio of as little as 1/10 is acceptable in extreme circumstances. The affect of these elements should always be considered when choosing a transducer. Please also be aware of the different methods of mounting an accelerometer and the effects of each of those methods on the measured data.
The following is a selection from the PCB catalog listing the characteristics of a transducer. Please note the items that we have discussed and note where they appear in a transducer specification

Band Limiting Filters

frequency weighting curve is defined in British Standard 6841:1987.
In addition to defining the frequency weightings for Hand­Arm and Whole Body, ISO 8041:2005 also defines a band­limiting filter to be used with each of the frequency weightings. Each band-limiting filter is a combination of a high-pass and low-pass 2nd order Butterworth filter, 12 dB per octave attenuation, with - 3 dB corner frequencies at the frequencies listed in table 3 below. When a frequency weighting is selected in the HVM100 Hand-Arm mode, or Whole Body mode, the HVM100 automatically places both the weighting filter and the appropriate band-limiting filter in the signal path.

The Auto-Range function in the HVM100 is designed to work with a steady state signal, i.e. an object which is vibrating at or near the level of your test object. Often this is the object or subject under test. It should be used prior to starting the actual measurement in order to optimize the input levels from each of the three axes of the transducer’s output based on actual vibration levels being produced by the object or subject under test. It is not meant for use while taking data. Before enabling this function, the transducer should be attached to the steady state vibration source to be measured. Next, find the Auto-Range display, located in the Range menu. Press the c key to enable auto-ranging. The HVM100 will use its Auto-Range algorithm to adjust the gain for all three channels such that the steady state input signal can be properly measured by the HVM100. (The gain is adjusted so that the signal falls within the top 20 dB of the HVM100’s analog to digital converter’s range.)
Auto-Range X= 0 Y= 0 Z= 0
The selections for the gain will be either 0, 20, 40, or 60 dB.

Once the gain selection is stable, press the c key to save the settings. The HVM100 must be stopped and reset before the Auto-Range function can be used.
Hint: This setting is in the Range menu. To access the Range menu press the
RANGE key and then use the u and d arrow keys to navigate
through the menu items.
A very efficient way to manually set the gain is to have the transducer mounted on the subject under test, as described in the section Auto Range on page 4-1, and check for indications of either under-range, described in the section Under­Range Indicator (?) on page 7-2, or overload, described in the section Overload Detection on page 7-1, and manually adjust the gain as necessary to avoid both.
NOTE: T o view each selection, first press
c key, and then press the r or l
the arrow key to scroll through each selec­tion.
The Gain settings in the HVM100 will perform manually what the Auto-Range setting did automatically.
You can select one channel at a time, and manually assign a gain setting to that channel. The choices are 0, 20, 40, or 60 dB.
To set the Gain for the X channel, first press the RANGE key to open the Range menu. Next press the d arrow key once to view the Gain X parameter. Press the u and d to enter the change mode, use the r or l arrow keys to select the desired value, and press the c key again to confirm the change. The Gain Y and Gain Z displays are located just below the Gain X display. (From the Gain X display press the d arrow key once to view the Gain Y display. Press the d arrow key again to view the Gain Z display.)

NOTE: Calibrators operate at a variety of frequencies. In order to ensure that the frequency weighting selection does not affect the level of the calibration, during calibration the frequency weighting is automatically changed to Fc frequency weighting which applies a bandlimiting filter from 6.3 Hz to 1250 Hz. This is indicated by the display of Fc in the upper right of the display during calibra­tion. This should accommodate most vibration calibrators.

Calibrate X, Y, Z

The Cal Level screen will allow you to enter the operating level of your calibrator. The frequency of the calibrator is also important, please see the adjacent note. To enter a value for your calibrator, go to the cal level screen, press the c key, use th e r or l arrow keys to select the position and use the u and d arrow keys to change the characters. When the proper level is entered, press the c key to return to the Range menu.The level must always be entered in g’s (rms).
Cal Level
1.000e+00 g rms
During calibration the gain of the HVM100 shoul d also be set so that the level of the calibrator is within the HVM100’s measurement range. For example, when using a 1.0 g rms calibrator and an accelerometer with a sensitivity of approximately 100mV/g, the gain should be set to 20 dB. For a 10 mV/g accelerometer, the gain should be set to 40 dB. A gain of 60 dB is appropriate for a 1 mV/g accelerometer. See appendix A for a complete listing of the HVM100’s measurement range.

Data Storage - File Registers 01 thru 99

Once all files have been purged (see chapter 3, Tools Menu), automatic and manual storing of files begins with file register 01. For example, if all files have been purged and there is data in the HVM100, pressing the DATA key, followed by the STORE key, will cause the following screen will appear (note, the file register shown will be 01).
Store File
If all files have been purged, and the Auto Store feature is enabled (see chapter 2, Getting Started), the HVM100 will automatically store the first file in file register 01. The second file will be automatically stored in file register 02 and so on until all 99 file registers are full.

Preserving the File Counter At Power-Off

The file counter, which keeps track of the last file register used, is saved when the HVM100 is turned off. For example, suppose you store 10 files in file registers 01 thru 10. Then, you turn off the HVM100. When the HVM100 is turned on again, if you try to store data, the HVM100 will prompt you to store data in file register 11, which is the next empty file register (see screen below).
Store File

A separate counter is used when you recall files. For example, suppose you recall and view files 01 thru 05. Then, you turn off the HVM100. When the HVM100 is turned on again, if you try to recall a file, the HVM100 will prompt you to recall file register 06, which is the next available file to view (see screen below).

Under-Range Indicator (?)

The under-range indicator will replace the bar graph run indicator whenever the channel currently displayed is under­range. The under-range indicator, like the bar graph, is inde­pendent for all three channels. A channel is under range whenever the input rms signal level is below the minim um RMS Range level as specified in the Typical Measurement Range tables in Appendix A. For example, with 0 dB gain, if the input rms level drops below 74 dBV (5 mV), the under­range indicator will be displayed

Run-Interrupted Indicator (!)

If the HVM100 is stopped and then run again without reset­ting the current data, the run-interrupted indicator (!) will replace the colon (:) in all displays that show the run time. The “!” indicates that the data in the HVM100 is not contig­uous. In other words, the instrument was stopped one or

NOTE: To view each selection, first pr ess the c key, and then press the r lu or d arrow key to scroll through each selec­tion.
NOTE: T he 2nd History setting (located in the Setup menu), controls whether or not the Peak levels are stored in the Time History.
Example: You have selected an Averaging time of Slow. This Averaging time
selected is the one second exponential detector, and if the 2nd History selection in the Setup menu is set to none, you will be able to store for 240 seconds. After 240 seconds the history will start erasing the data from the beginning of the Time History buffer to make room for the incoming data. If the 2nd History selection is set to Peak, then you will have 120 seconds of storage time, and after that, the Time History buf­fer will begin to erase from the beginning to make room for the new data.
The HVM100 will store a time history based on the sample time selected. The Time History buf fer has 240 entries avail­able for storage. If you select to store the Peak values as well as the RMS values, the number of time history records is cut in half to 120.

AC/DC Output Connector

Example: Chart recorder output, monitoring the
DC output, with an averaging time of 60 seconds.
AC output is useful for frequency analysis by an external analyzer or for recording in a tape recorder. The DC output is useful for a chart recorder, or to measure the voltage proportional to the RMS or peak value.
The DC output is updated according to the averaging time. If the averaging time is set to slow, the signal on the DC output pin for the selected channel will be updated once per second. If the averaging time is set to 60 seconds, the signal on the DC output pin for the selected channel will be updated once every 60 seconds.
The AC output will produce a signal from 0 - 0.5 Volt RMS.
The scale of the DC output is typically 5 mV/dB. The level typically varies between 0 Vdc to +1.0 Vdc.
