Test technology for custom tasks
By closely working together with test bench engineers, we are able to create measurement systems that meet your needs and test these systems as early as the development phase under test bench conditions. With the achieved product extensions and product improvements, additional aims were able to be met relative to changing environmental and component pressures and which are called for to support reliable handling in operation.
With over 30 years of experience and deep expertise, we develop custom-tailored test and measurement technology for testing your vehicles. That means that with measurement technology from ATESTEO, you receive solutions precisely tailored to your needs and measurement, testing, and analytic challenges.

Customer-specific measurement technology
ATESTEO’s electronic development department, integrated in the area of customer-specific measurement technology, has extensive expertise in the further development and new development of electronic measurement systems.
Measuring amplifier for DMS
The ATESTEO strain gauge amplifier system processes the signals from sensors supplied on strain gauge basis in a bridge circuit. For this purpose, the SAFO provides a reference voltage to supply the bridge and converts the incoming differential voltage into a frequency in the range of 60 kHz + 20 kHz. With the SAFO 1.3 a temperature compensation curve for the internal electronics is recorded ex works and stored in an EEProm. The user can switch the temperature compensation on or off as desired.
SAFO 1.3 – Features
- Torque-proportional frequency output [Hz] of 60 kHz + 20 kHz
- Gain adjustable by DIL-switch in the range 1-10.000
- Automatic zero point adjustment (16 bit resolution) at the touch of a button or via serial interface
- Serial interface with terminal function
- Calibration jump
- Measurement and display of the electronics temperature in the range 0 °C-125 °C (0.5 °C resolution) with measuring point compensation option
- Resettable operating hours counter
- Optional external temperature measurement via thermocouple with measuring point compensation option
- Optional switchable input from voltage +10 V/+5 V to strain gauge amplifier
- Optional single-line 7-digit display
SAFO 2.3 – Features
- Strain gauge amplifier with frequency output [Hz] in the range 60 kHz + 20 kHz
- Galvanically isolated analogue output + 10V and + 20 mA and 4-20 mA
- Gain adjustable via serial interface in the range 0.3077mV/V and 14.2857mV/V.
- Automatic zero point adjustment at the push of a button or via serial interface
- Serial interface with terminal function
- Measurement and display of the electronics temperature in the range 0°C-125°C (0.5°C resolution). (maximum operating temperature of the electronics: 70°C)
- Resettable operating hours counter
- Optional CAN-Bus interface
Vibration monitoring systems
Structure-borne sound monitoring systems are used to monitor sensitive drive components. These systems are equipped with a robust piezoelectric sensor as vibration transducer. The sensor is mounted directly on the critical bearing points of blowers, pumps and other drive components. Bearing damage is indicated by increased noise emissions.
The structure-borne noise monitoring system measures the structure-borne noise emissions occurring during operation with the help of the internally or externally mounted sensor and can thus detect changes. If a freely adjustable threshold value is exceeded, a switching output is set, which is reset once the value falls below the threshold. Usually this output is used to issue a warning. Further outputs can be used to switch off and lock the monitored machine.
