Frequently Asked Questions
Q
What pressure types does this pressure sensor support?
This pressure sensor supports three pressure types: compound pressure (rated range -100～100kPa), positive pressure (rated range -0.1～1MPa), and vacuum pressure (rated range 0～-101.0kPa). The withstand pressure for each type is 500kPa for compound and vacuum, and 1.5MPa for positive pressure.
Q
What is the output type and communication interface of this sensor?
The sensor features an open collector output supporting both NPN and PNP configurations (up to 1 channel output). It also supports RS485 communication with a maximum connection distance of ≤1200m and baud rates of 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps.
Q
What industries and applications is this pressure sensor suitable for?
This sensor is designed for a wide range of industrial applications including pipeline pressure monitoring, air leak testing, F.R.L (Filter, Regulator, Lubricator) systems, gas storage cylinders, adsorption verification, and air compressors. It is compatible with air and other non-corrosive, non-flammable gases.
Q
What are the operating and storage temperature ranges for this sensor?
The sensor operates within an ambient temperature range of 0～50℃ and a humidity range of 35～85% (no water condensation). For storage, the temperature range is -10℃～60℃ (without water condensation or freezing). The temperature characteristic is ±3%F.S with a reference temperature of 25℃.
Q
How accurate is the pressure sensor's display and measurement?
The display accuracy is ±1%F.S ±1digit at 25±3℃, with a repeatability accuracy of ±0.3%F.S ±1digit and linearity of ±1%F.S. The display refreshes 5 times per second, and the response time is ≤2.5ms (adjustable to 25, 100, 250, 500, 1000, or 1500ms).
Q
What is the protection grade and vibration/impact resistance of this sensor?
The sensor carries an IP40 protection grade. It is vibration-resistant with an amplitude of 1.5mm at 10Hz～55Hz～10Hz per minute for 2 hours in each X, Y, and Z direction. For impact resistance, it withstands 100m/s² (10G) for 3 times in each of the X, Y, and Z directions, making it suitable for demanding industrial environments.
