Measurement Transducer QMB6
The QMB6 quartz measurement box combines simplicity of operation with unrivaled accuracy in a compact form factor, delivering precise measurements at up to 0.01 Hz frequency resolution for 2 sensor channels.
You can purchase the Measurement Transducer QMB6 directly in our Onlineshop.
Features & Benefits
- 2 independent measurement channels
- High frequency resolution of up to 0.01 Hz
- ModBUS protocol for ease of integration
- 4 communication interface options: RS232/RS485, USB or Ethernet (PoE)
- Includes low noise integrated oscillator
- Unmatched low-cost compact unit performance
- All connecting cables, power supply and Windows Software included
Quartz sensors can be either directly connected utilizing the integrated low noise oscillator or linked via external oscillators when the QMB6 is installed at larger distance from the sensor.
The QMB6 is available with 4 hardware communication standards RS232/485, USB and LAN/Ethernet with PoE option. The latter simplifies installation in an Ethernet infrastructure network.
Monitoring and data logging can be performed by either using the supplied Windows software or by integration into a host environment utilizing the industry standard ModBUS protocol.
