Frequently Asked Questions (FAQ)
Q
What pressure ranges does this pressure sensor support?
The sensor supports three pressure types: high pressure (rated range 0.000～2.000MPa, withstand up to 3.0MPa), positive pressure (-0.100～1.000MPa, withstand up to 2.0MPa), and compound pressure (-100～100kPa, withstand up to 500kPa), making it suitable for a wide variety of industrial applications.
Q
What is the protection grade of this pressure sensor?
The sensor carries an IP65 protection rating, meaning it is fully protected against dust ingress and resistant to low-pressure water jets, making it reliable for use in demanding industrial environments such as pipeline monitoring and air compressor systems.
Q
Does the sensor support RS485 communication, and what is the maximum communication distance?
Yes, the sensor supports RS485 communication with a maximum connection distance of ≤1200m. It supports multiple baud rates including 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, providing flexible integration into various control and monitoring systems.
Q
What types of gases is this sensor compatible with?
The sensor is compatible with air and non-corrosive, non-flammable, corrosion-resistant gases. It is not suitable for use with corrosive or flammable gas media. Typical applications include air leak testing, F.R.L units, and gas storage cylinders.
Q
What is the output type and how many outputs does the sensor provide?
The sensor features an open collector output type, supporting both NPN and PNP configurations, with up to 2 outputs available. The load current is ≤200mA, and the response time is ≤2.5ms (adjustable to 25, 100, 250, 500, 1000, or 1500ms).
Q
What are the operating and storage temperature ranges for this sensor?
The sensor operates reliably within an ambient temperature range of 0～50℃ and can be stored at temperatures between -10℃ and 60℃ without water condensation or freezing. The humidity range for both operation and storage is 35～85% (no water condensation).
