Q1: What should I check before installing an explosion-proof differential pressure sensor?
A1: Before installation, check the pressure range, gas compatibility, medium temperature, output signal, hazardous-area certification, pressure port connections, electrical wiring, and environmental conditions. Correct installation is essential for both measurement accuracy and safe operation.
Q2: Does the explosion-proof differential pressure sensor have temperature compensation?
A2: Yes. The explosion-proof differential pressure sensor provides temperature compensation within -10°C to 60°C. This helps reduce measurement errors caused by temperature changes within the specified compensation range.
Q3: What medium can this explosion-proof differential pressure sensor measure?
A3: This explosion-proof differential pressure sensor is designed for gas measurement, provided that the gas is compatible with the sensor's wetted materials. The media compatibility should be confirmed before selecting the sensor for a specific application.
Tips: Is this explosion-proof differential pressure sensor suitable for outdoor installation?
Yes. This explosion-proof differential pressure sensor can be used for outdoor pressure monitoring when the installation environment is within its specified operating conditions. Its IP65 protection rating helps protect the sensor against dust and water jets, making it suitable for many industrial outdoor applications. For hazardous locations, always confirm that the specific explosion-proof certification matches the site's classification and installation requirements.
