The Swiss army knife of pressure sensors -
custom pressure transmitter with four calibrated pressure ranges

The challenge:
A robust sensor system was needed for an automotive diagnostic unit that could be used for multiple measuring tasks in a flexible way, to measure air, oil, fuel, and cooling fluid pressures, and at the same time was suitable for rough shop floor environments.

The solution:
Sensortechnics developed a sensor that can be connected to the various applications using a quick-fit pressure fitting, so enabling service staff to handle it in an easy and user-friendly way. Four calibrated partial pressure ranges were defined within a standard pressure range of -15...500 psi to be selected separately depending on the measurement task. For each pressure range, a microcontroller calculates an error corrected signal/pressure characteristic, depending on the accuracy requirements of the particular measurement task.
