Frequently Asked Questions (FAQ)
Q
What is the maximum withstand pressure of this pressure sensor?
The sensor supports up to 3.0MPa for high pressure models, 2.0MPa for positive pressure models, and 500kPa for compound pressure models. These ratings ensure safe and reliable operation across a wide range of industrial applications.
Q
What is the IP protection rating, and is it suitable for dusty or wet environments?
This pressure sensor carries an IP65 protection rating, meaning it is fully dust-tight and protected against water jets from any direction. It is well-suited for use in industrial environments where dust and moisture are present.
Q
What types of gases is this sensor compatible with?
The sensor is designed for use with air and non-corrosive, non-flammable, corrosion-resistant gases. It is not recommended for use with aggressive, flammable, or corrosive media without prior consultation.
Q
