Couldn't load pickup availability
The QYB500 is a robust five-wire pressure transmitter designed for applications requiring high-performance signal isolation, dual-channel output, or specialized industrial wiring. Its integrated digital display and explosion-proof housing make it suitable for use in hazardous environments and complex process systems.
The device offers flexible analog output formats and maintains long-term accuracy through built-in temperature compensation. With a corrosion-resistant stainless steel structure and a submersible probe option, the QYB500 is ideal for both pressure and liquid level monitoring.
Applications:
Liquid level monitoring in tanks and wells
Chemical and petrochemical pressure systems
Water treatment and municipal supply systems
Machinery and pump station integration
Explosion-proof zones (oil, gas, dust environments)
Remote data transmission in SCADA or Modbus systems
