MPL 9390 Series
Overview

Scroll

MPL / Switches & Sensors 9390 Series /
Low Pressure Switch

The MPL 9390 series is a pressure to voltage transducer with output conditioned and amplified by a programmable ASIC, suitable for blower vacuum, combustion air modulation, liquid level and many other applications. Differential or vacuum-only models are available. Standard models are available for 0-4 or 0-10 in/H2O with output of 0-5VDC.

 

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.

 

Applications Include:

Low pressure, variable output sensor, combining diaphragm and strain gage technologies to provide an economical but robust alternative.
