Abstract

Background. Operation of sensors in a wide temperature range requires additional temperature error correction. The aim of this work is to develop a measuring circuit for high-temperature capacitive pressure sensors allowing to eliminate the temperature error and to ensure the invariance of the output signal to cable parameters.
Materials and methods. When developing the measuring circuit the authors used fundamentals of measuring device’s circuit design.
Results and conclusions. The article considers methods of sensors’ temperature error correction using the temperature-dependent capacity. The author’s have developed a microprocessor-based measuring circuit for high-temperature capacitive pressure sensors and suggested a calculation algorithm for the measuring circuit’s output signal.

Key words

capacitive sensor, temperature error, temperature-dependent capacity, error correction
