IN-HOUSE MAINTENANCE
The most important part of in-house maintenance is the calibration of the cylinder pressure sensor.
These factors define the demand for a calibration unit
• Request for instant calibration within a short time
• The charge for the calibrations needed inside one year exceeds the annual costs for in-house maintenance
• Use of optimum performance based on continuous calibration
RCU 601/300
To cover these requirements AVL developed an automated system for calibrations
for temperatures up to 250 °C and pressures up to 300 bar. In the Ramp
Calibration Unit RCU 601/300 a computer controlled spindle generates an
increasing hydraulic pressure to the sensors under test. The signals are related
to the response of the build in reference sensor. The calibration software allows
customized documentation and the connection to the SDB Sensor Database
which enables central management and coordination of calibration schedules.
By using AVL charge amplifiers the system is able to identify the sensors under
test automatically via the SID Sensor Identification system and link it with the
corresponding information in the SDB Sensor Database. It is also possible to
verify measurement chains (sensor + amplifier) and low pressure sensors from 0
to 4 bar up to 0 to 30 bar.
BENEFITS AT A GLANCE
• Fully automated operation – no manual spindle
operation is needed to apply the pressure
• Up to 6 sensors can be calibrated at once which
reduces the time of the calibration procedure
• Cold and hot calibrations are possible with one system
• Temperature isolated absolute reference pressure
sensor ensures reproducible and accurate calibrations
• Standardized calibration sheets can be generated
by the software
• A sensor history is build up and stored in the SDB
Sensor Database to track and monitor the sensor
performance
• Clear step by step guidance due to the user friendly
software interface
