MPL / Switches & Sensors 9391 Series /
Low Pressure Switch
The MPL 9391 series is an ultra-low pressure, high accuracy semiconductor-based transducer affording a precision ratiometric output stable over temperature and time. Ideal for digital combustion control and high-performance applications. Differential or vacuum-only models available. Standard models available from 0-1 to 0-10 inH2O with a configurable 5VDC ratiometric output.
The MPL 9391 is ideal for new high-efficiency heating applications requiring feedback for intelligent controllers, ECM motors, logic-controlled blowers and other smart components for modulating furnace control applications. This may include blower vacuum, combustion air modulation, liquid level and many other applications.
Applications Include:
- Air Flow Monitoring
- Blower Modulation
- Process Controls
- Automation & Medical
