Frequently Asked Questions
Q
What pressure types does this pressure sensor support?
This pressure sensor supports three pressure types: micro pressure (rated range -10～10kPa), positive pressure (rated range -0.100～1.000MPa), and compound pressure (rated range -100～100kPa), making it suitable for a wide variety of industrial applications.
Q
What gases is this sensor compatible with?
The sensor is compatible with air, non-corrosive, and non-flammable gases (general type). A water-resistant type is also available for use with air that contains condensed water, as long as the gas remains non-corrosive and non-flammable.
Q
What is the maximum RS485 communication distance supported?
The RS485 communication distance supports a maximum connection distance of ≤1200m, making it well-suited for long-distance industrial monitoring and control systems.
Q
What are the operating and storage temperature ranges?
The ambient operating temperature range is 0～50℃. For storage, the sensor can withstand temperatures from -10℃ to 60℃, provided there is no water condensation or freezing during storage.
