Thru-Hole Mountable Pressure Monitoring Device – PMD Series

The PMD Series is a thru-hole mountable pressure monitoring device that is ideal for low to medium pressure applications.

Company: Merit Sensor is a leader in piezoresistive pressure sensing and partners with clients to develop high performing solutions for a range of applications and industries.

Technology: Merit Sensor utilizes a piezoresistive Wheatstone bridge in a design that anodically bonds glass to a chemically etched silicon diaphragm. All products are RoHS compliant.

Sentium: Merit Sensor products add a proprietary Sentium® technology, designed to provide a best-in-class operating temperature range (-40 °C to 85 °C) and excellent stability.

Capabilities: Merit Sensor designs, engineers, fabricates, dices, assembles, and tests products from an advanced facility near Salt Lake City, Utah.
