Merit Sensor Demonstrates Pressure Measurement in a Diesel-Particulate Filter

We take pride in our pressure sensors and like to show what they can do. Recently at the Sensor+Test trade show in Nuremberg, Germany, we used a diesel-particulate filter (DPF) to demonstrate how our sensors can be used to indicate when a DPF is clogged with particulate and needs to be regenerated.

A couple of our senior engineers integrated one of our pressure sensors into a modern-day DPF. This engineering work included designing and 3D printing a coupler to connect a fan to the input end of the DPF, simulating the flow of exhaust; 3D printing a custom fan guard and generic housing for the pressure sensor; and programming a microprocessor to vary the fan speed automatically.

Our TR Series is an ideal choice for the DPF because it is impervious to harsh media, such as exhaust, and contains a MEMS die that ranges from 0 to 500 psi. For this application the MEMS die in the TR Series would be produced in a gage configuration, enabling it to measure pressure from the backside as well as the top side. The TR Series would then be calibrated for a differential output.

The main purpose of this demonstration was to show another one of our solutions to a real-world application. The DPF is just one of many applications for which our products are designed. We thrive on understanding our customers’ applications and providing the best solution for each one.

Merit Sensor Partners with Global Electronics Corporation


To our valued customers:

We are pleased to announce a distribution-sales partnership with Global Electronics Corporation based in Tokyo, Japan.

Global Electronics is a diversified electronics corporation serving high-tech companies with electronic-components distribution services, analog and sensing-technology expertise, in-house design and engineering, manufacturing, and technical-support capabilities.

Merit Sensor Employees Serve Breakfast

A group of Merit Sensor employees and their families recently cooked and served breakfast to parents staying at Salt Lake City’s Ronald McDonald House. Guests at the facility live outside the Salt Lake area and have children who require medical attention in Salt Lake City. The Ronald McDonald House provides these parents a place to stay, allowing them to be near their hospitalized children. The meals are provided exclusively by volunteers.

This service opportunity allowed the families of Merit Sensor employees to become acquainted with one another. The kids were happy working together; even the youngest of them flipped and served pancakes. The older kids scrubbed dishes and made cookies, while the adults cooked sausage, eggs, and bacon.

The event was organized by Wayne Rowley, manager of purchasing and procurement at Merit Sensor, who, in this case, procured the food. Many of Merit Sensor’s employees work hard not only to produce and provide pressure sensors, but also to make their community a happier place.

Rick Russell Addresses the Micro Nano Technology Special Interest Group at the University of Utah

Merit Sensor’s president, Rick Russell, spoke recently as the keynote speaker for the Micro Nano Technology (MNT) Special Interest Group to a group of approximately 80 U.S. college educators gathered at the University of Utah. The event is “a venue to share ideas and learn from others who work to educate technicians, a place to stay on the forefront of industry and workforce needs, and a forum to network and share ideas on ways to strengthen and augment workforce development programs through educational partnerships with industry for tomorrow’s micro and nano technology workforce” (MNT 2017 Special Interest Group Program).

Rick Russell, President of Merit Sensor, was presented with a 6-inch wafer as a token of appreciation for addressing the Micro Nano Technology Special Interest Group at the University of Utah on July 18, 2017.

With over 20 years of experience working with MEMS (microelectromechanical systems), Rick has valuable industry insight to offer educators and their students. In his speech he emphasized the importance of teachers stimulating students’ interest in science and experimentation and the importance of pulling some of the less-than-stellar students out of their shells because, he argued, they are sometimes the most valuable employees in the workplace. “I can’t say enough,” he said, “about getting the kids involved.” Organizations like the Micro Nano Technology (MNT) Special Interest Group are important to companies, like Merit Sensor, that value the way students are educated and encouraged. Some of the students could end up working in the field of MEMS pressure sensors and even for Merit Sensor.

The workforce at Merit Sensor by in large comprises electrical, mechanical, and chemical engineers; technicians; and operators. The company is highly dependent on technical knowledge and skills and, therefore, looks to today’s students to bring fresh knowledge and enthusiasm to help it stay at the forefront of the industry in the face of tomorrow’s challenges.

Congratulations to the winner of the Apple Watch drawing!

We want to send a big thank you to everyone who came by our booth at Sensors Expo and participated in our crossword puzzle contest. A special congratulations to Juergen Zach, of Pentair, who won the drawing for the Apple Watch prize.  We had a tremendous turnout with a lot of entries. All the entries […]

Custom Pressure Sensors for the Aerospace Industry

The aerospace industry is known for having some of the harshest environments on the planet and finding a pressure sensor to withstand those harsh environments can be extremely difficult.  The TR Series pressure sensor and HM Series MEMS sensing element are built to withstand temperatures as low as -40°C and as high as 150°C, making them ideal candidates for the Aerospace industry.  The TR Series and HM series measure pressure via direct media pressure sensing to the backside of the die.  Direct media pressure sensing translates into excellent system design flexibility leading to lower cost and ease of manufacture.

So whether your application is Flight control surface positioning, auto-pilot, jet engine throttle and thrust reverser controls, auto-pilot input, landing gear steering and thrust vector control, turbine guide vane, valve controls, turbine actuators, and engine controls or any other number of Aerospace applications Merit Sensor has the right sensor assembly or MEMS sensing element for you.

Merit Sensor Systems, Inc. has partnered with customers for more than 20 years to design, fabricate, assemble and package reliable, cost-effective piezoresistive pressure sensor solutions.

Merit Sensor offers full-service design capabilities, in-house wafer fabrication, flexible shipping, packaging and assembly, piezoresistive technology (PRT), expansive pressure ranges (0.15 psi to 15,000 psi), complete pressure measurement (absolute, gage, differential and vacuum). Additionally, Merit Sensor is able to provide unparalleled flexibility to customize pressure sensing solutions to fit into our customers’ applications. Most customers in the Aerospace industry require a high level of customization because of the demand of the applications.

Unlike other pressure sensor suppliers, Merit Sensor can provide customers with completely customized pressure sensor designs with large or smaller/limited production runs. Our customers range from pressure sensor transducer manufacturers who are already experts in pressure sensing technology and rely on Merit Sensor for highly stable and sensitive MEMS sensing elements (bare die), to customers who have little to no experience in the pressure sensing world and look to Merit Sensor to assist with a completely custom design and implementation of a pressure sensor that best fits their application.

At Merit Sensor our engineers are application experts. We are ready to help customers design your application to work with a pressure sensor, and/or design a customized pressure sensing solution that works for your application. If you are unsure whether a pressure sensor is right for your application, Merit Sensor can help you make that determination.
