Frequently Asked Questions
Q
What types of pressure can this sensor measure?
This pressure sensor supports three pressure measurement modes: compound pressure (−100～100 kPa), positive pressure (−0.1～1 MPa), and vacuum pressure (0～−101.0 kPa). It is versatile enough to cover a wide range of industrial pneumatic and fluid monitoring applications.
Q
What gases is this sensor compatible with?
The sensor is designed for use with air and other non-corrosive, non-flammable gases. It is not suitable for corrosive or flammable gas environments, as these could damage the internal sensing elements or pose a safety risk.
Q
What is the communication interface and maximum communication distance?
The sensor features an RS485 communication interface supporting baud rates of 9600, 19200, 38400, 57600, and 115200 bps. The maximum RS485 communication distance is up to 1200 meters, making it ideal for long-distance industrial monitoring systems.
Q
What is the operating and storage temperature range?
The sensor operates within an ambient temperature range of 0℃ to 50℃. For storage, it can withstand temperatures from −10℃ to 60℃ without water condensation or freezing. The humidity range for both operation and storage is 35～85% (non-condensing).
Q
What output types does this sensor support?
The sensor provides an open collector output supporting either NPN or PNP configuration, with up to 1 channel of switching output. The load current is ≤200mA and the output voltage range is 0.6V～5V (±2.5%F.S at rated voltage). This makes it compatible with a wide variety of PLCs and control systems.
Q
What industries and applications is this sensor best suited for?
This sensor is widely used across multiple industrial sectors, including pipeline pressure monitoring, air leak testing, F.R.L units (Filter, Regulator, Lubricator), gas storage cylinder monitoring, adsorption verification systems, and air compressor pressure control. Its compact design and high accuracy make it a reliable choice for pneumatic automation environments.
