History

For 30 years we have been supplying customers with accurate and reliable MEMS piezoresistive pressure sensors. Here’s a quick recap of our history:

In 1991 Fred Lampropoulos, Chairman and CEO of Merit Medical Systems, founded Sentir Semiconductor. The company’s first pressure sensor was qualified for production in 1993, and in 1997 the company’s annual sensor sales surpassed 1 million.

In 1999 Sentir Semiconductor was vertically integrated with Merit Medical, and in 2002 the name Sentir Semiconductor was changed to Merit Sensor Systems. In 2004 the building of a new and improved facility on the Merit Medical campus commenced, including a class 100 (ISO 5) cleanroom for wafer fabrication, commonly known in the industry as a fab.

Today, Merit Sensor continues to provide pressure sensors to its parent company. However, Merit Sensor serves many other customers from various industries around the world. With its own wafer fab and calibration equipment on site, Merit Sensor has been able to support a wide variety of market demands.

Whether the industry be transportation, industrial, medical, aerospace, or consumer, Merit Sensor provides products for accurate and reliable measurement of pressure.

Capabilities

We design and manufacture MEMS silicon dies that measure pressure from 0 to 15,000 psi in sensing environments from -40 to 150 °C. Our pressure-sensor dies are available in absolute, gauge, vacuum, and diferential configurations.

We also design and manufacture various pressure-sensor packages for integration into the applications of our customers. Some examples of our packaged sensors are the fully compensated TR Series, ideal for mass production in the automotive industry; the passively compensated BP Series, ideal for the room-temperature environment of medical devices; and the uncompensated RS Series, ideal for soldering and later calibrating on a control board.

In addition to our standard products designed for various applications, we also customize products to meet the specific needs of our customers (e.g., sensitivity, resistance, calibration). If the requirements are feasible and the NRE payment is sufficient, we will work closely with those customers who require a customized sensor.

Having a wafer fab on site allows us to closely monitor and control our processes and ensure that high-quality parts are produced.* All of our products are RoHS, REACH, and AEC-Q100 compliant. We are also certified to ISO 9001:2015 (quality management system) and ISO 14001:2015 (environmental management system). Even if issues do arise, we are committed to quality and customer service. We will provide our customers with solutions.

*Mission Statement: Merit Sensor Systems will design and manufacture quality products, specifically silicon-based sensors and micromachined components for the OEM and private label market. This will be accomplished by market focus, education, innovation, quality, and service.
