2. Operating Principle and Application Notes
The accelerometer‘s sensor is MEMS-based. MEMS stands for “Micro-Electro-Mechanical Systems”. In this
case, the measurement principle is capacitive and offers the following advantages:
✓The basic sensor system (in contrast to piezo-based acceleration sensors) do not represent an uncon-
trollable source of energy in the limit range. Thus, the system is very quickly ready for measurements
again - even in the event of unexpected shocks (within 500 µs)
✓Static measurements are possible, i.e., frequencies starting from 0 Hz can be evaluated.
✓No additional measuring amplifier is required
The basic MEMS sensor is electrically installed into the accelerometer as follows:
Figure 1: Block diagram
Under overload, for example, an accelerometer with a measuring range of ± 50 g exhibits the following signal
behavior:
Figure 2: Signal behavior under overload (source: Analog Devices)
As can be seen in Figure 2, the output signal (red, -40...60 g) follows the acceleration load (blue, -40...150 g)
until the measuring range limit is reached. The output signal is limited by the supply voltage and does not
increase further when the load is increased. Approximately 0.5 ms after exceeding the measuring range

limit, the over-range output (black, 0...5 V) signals for 0.5 ms that the measuring range has been exceeded.
The MEMS sensor then checks whether operation is within the measuring range limits. In the figure, this is
not the case again until a few 0.5 ms cycles later, whereupon the sensor registers the correct values again
within a 0.5 ms cycle.
When using the product, please consider the
▪Maximum load limits
▪Safety factors from special safety regulations (e.g., EX areas, regulations for personal and plant pro-
tection)
▪Environmental conditions.
Also observe the following safety instructions and installation guidelines.

3. Safety Instructions
3.1. Intended Use
The accelerometers BA are sensors for the metrological detection of vibrations on components or machine
elements within the operating limits of the sensor.
Any other use is not in accordance with the intended use.
To ensure safe operation, the product may only be used in accordance with the information in these assembly
instructions and in compliance with the following safety regulations and the technical data provided. During
use, the legal and safety regulations required for the respective application must also be observed. This also
applies analogously to the use of accessories.
The accelerometers are not intended for use as safety components. Proper transport, professional storage and
assembly as well as careful operation and maintenance are prerequisites for faultless and safe operation of
the accelerometers.
3.2. Operating Personnel
This product must be installed and operated exclusively by qualified personnel in accordance with the tech-
nical data in connection with the safety provisions and regulations set out below.
Qualified personnel include persons who, as operators of the equipment under investigation, have been in-
structed in its handling and safety concepts and are familiar with the operation of the product described in
this documentation. They must have read and understood the assembly instructions and the safety instruc-
tions carefully.
When using the accelerators, the legal and safety regulations required for the respective application must also
be observed. This also applies analogously to the use of accessories.
Ensure that work is carried out in a safety-conscious manner and compliance with the relevant accident pre-
vention regulations, e.g., those of the employers’ liability insurance associations.
3.3. Safety Regulations and Load Limits
For safe operation of the product, it is essential to observe the assembly instructions and load limits. The max-
imum loads specified in the technical data sheets must not be exceeded under any circumstances. This con-
cerns:
▪Maximum shock acceleration
▪Temperature limits
Signal cables of the sensors must be installed in such a way that electromagnetic emissions do not impair the
sensor function.
Prior to each commissioning, project planning and risk analysis must be carried out, considering all safety
aspects of the surrounding technology. In particular, this concerns personal and plant protection. Supplemen-
tary safety precautions must be taken to prevent defects or faults in equipment that could result in personal
injury, equipment damage, or loss of data.

3.4. Supplementary Safety Precautions
As passive sensors, accelerometers cannot perform any safety-relevant functions. This requires additional
components and equipment for which the installer and operator are responsible. Electronics that process such
a measurement signal must be designed in such a way that no consequential damage can occur if a measure-
ment signal fails.
In the event of a fault, in which persons or property may be harmed by loosening or malfunctioning of the
product, the user must take precautions to ensure a safe operating state. Such precautions can be imple-
mented, for example, by means of separating or non-separating protective devices or the like and must at least
meet the requirements of the relevant accident prevention regulations.
3.5. General Hazards due to Non-observance of the Safety Instructions
The accelerometers correspond to the state of the art and are operationally safe. There are residual risks as-
sociated with improper use. For this reason, every person who is entrusted with the installation, commission-
ing, and dismantling of the sensor must read and understand the operating instructions and, in particular, the
safety instructions.
Improper use of the accelerometer or failure to observe the safety regulations can result in damage, malfunc-
tion, failure, or loosening of the accelerometer. In particular, loosening the accelerometer can cause damage
to property or persons in the vicinity of the accelerometer.
The scope of services and delivery of the product covers an accelerometer up to the standardized connection
and is only part of the measurement chain. Safety-related aspects of the measuring chain must also be planned,
implemented, and accounted for by the system planner/supplier/operator in such a way that residual risks
are minimized and identified. Existing regulations must be observed.
3.6. Modifications and Change
The product must not be modified without the express consent of the manufacturer. Any change excludes the
manufacturer's liability for any resulting damage.

4. Conditions and Preparations on Site
Ensure that the accelerometers BA are protected from adverse conditions such as salt water, snow, rain. or
ice.
Protect the contact points from contamination and do not touch the terminals.
A constant temperature within the operating range affects the sensitivity of the accelerometers only to a small
extent.
You should avoid using the accelerometer in extreme humidity (>90 % relative humidity, or thawing atmos-
phere). Accelerometers with connected signal cable have protection class IP67 according to DIN EN 60529.
This protection class is only guaranteed if the connector is properly mounted on the accelerometer.
The accelerometer is made of stainless steel. Ensure that the accelerometers do not come into contact with
chemicals that can attack the surface. Protect the signal cable from aggressive chemicals. Acids and other cor-
rosive substances release ions that can cause the accelerometer to fail. In this case, please initiate appropriate
protective measures.
Note: Contaminated, painted or damaged screw connection points prevent sustainable mounting of the accel-
erometers. Ensure that the installation location is level to allow the sensor to be mounted flat.

5. Mechanical Installation
5.1. General Installation Guidelines
Handle the accelerometers gently. You thus prevent damage that can impair the mounting of the accelerome-
ter or signal cable as well as the measurement signal. The signal interface connection should be easily acces-
sible.
Make sure that the accelerometer is not overloaded. In the event of an overload, there is a risk of damage or
loosening, resulting in hazards for operating personnel and equipment. Take appropriate measures to protect
against overload or to safeguard against the consequences of loosening.
5.2. Installation
The accelerometers can be attached to the specimen using the supplied M5x20 cap screws of grade A2 or A4
according to ISO 4762/similar to DIN 912. The tightening torque is between 4 and 6 Nm, depending on the
thread and friction conditions.
During assembly, make sure that the accelerometer is not overloaded.
