Wiring Diagram
Q1: Can this pressure sensor be used in an air compressor system?
A1: Yes. This ceramic capacitive pressure sensor can be used in air compressor systems to monitor compressed air pressure for industrial control and equipment operation.
Q2: What is the maximum pressure a ceramic capacitive pressure sensor can measure?
A2: The ceramic capacitive pressure sensor can measure pressures up to 7 MPa, depending on the selected model and pressure range configuration. For applications requiring negative pressure measurement, ranges down to -0.1 MPa are also available. Refer to the pressure range selection table to choose the appropriate model for your operating conditions.
Q3: Is a ceramic capacitive pressure sensor suitable for high-temperature applications?
A3: Yes, within its specified temperature limits. This ceramic capacitive pressure sensor supports medium temperatures from -40°C to 85°C, with a temperature compensation range of -20°C to 80°C. For high-temperature applications, ensure the process temperature remains within the rated range and consider the effects of temperature drift on measurement accuracy. For temperatures above 85°C, select a pressure sensor specifically rated for higher-temperature operation.
Tips: What factors affect pressure sensor measurement accuracy?
Several factors can affect pressure sensor measurement accuracy, including temperature fluctuations, pressure range selection, long-term drift, installation conditions, power supply stability, and signal interference. To maintain reliable measurements, select the appropriate pressure range, operate within the specified temperature limits, ensure correct wiring and installation, and perform periodic calibration when required.
