Applications

For over 20 years Merit Sensor Systems has partnered with customers to design, fabricate, assemble and package reliable, economical piezoresistive pressure sensor solutions for automotive, industrial, defense, medical, aviation and consumer applications.

Merit Sensor provides full-service design capabilities, flexible shipping, piezoresistive technology (PRT), in-house wafer fabrication, packaging and assembly, complete pressure measurement (absolute, gage, differential and vacuum) expansive pressure ranges (0.15 psi to 15,000 psi), and unmatched operating temperature range (-40 °C to 150 °C) via Merit Sensor’s Sentium® process. Furthermore, Merit Sensor is able to provide unparalleled flexibility to tailor pressure sensing solutions to match customers’ applications.

In contrast to other pressure sensor suppliers, Merit Sensor can offer customers totally customized pressure sensor designs with large or smaller/limited production runs. Merit Sensor’s customers range from pressure sensor transducer manufacturers who are already experts in pressure sensing technology and depend on Merit Sensor for extremely stable and sensitive MEMS sensing elements (bare die), to customers who have limited to no experience in the pressure sensing world and seek Merit Sensor to assist with a totally custom design and implementation of a pressure sensor that ideally fits their application.

At Merit Sensor, engineers are application experts. They are ready to assist customers design the application to work with a pressure sensor, and/or design a tailored pressure sensing solution that suits specific applications. In case a customer is unsure whether a pressure sensor is right for a particular application, Merit Sensor can help make that choice.
