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 for automotive, medical, industrial, aviation, defense and consumer applications.
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) and unmatched operating temperature range (-40°C to 150°C) via our Sentium® process. Additionally, Merit Sensor is able to provide unparalleled flexibility to customize pressure sensing solutions to fit into our customers’ 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.

Standard Part Numbers
What do you mean by “media” and what is “harsh media”?
Media is the environment to which the sensor is exposed. Generally, this can be liquid, gas or air. Harsh media would be anything that could damage the sensor and electronics such as gasoline, oil, exhaust, water, etc…
What is the “backside” of the die?
The backside is the cavity side of the die.
Can I evaluate your pressure sensor products?
Yes, in fact Merit sells a TR evaluation kit (MeriTREK) that allows the end user to evaluate the TR –Series fully compensated pressure sensor. The MeriTREK ships with a standard 100psi TR part but will work with any pressure range of the TR Series. In addition Merit offers samples of other parts and bare-die for the customer to evaluate.
