Our History


Process Sensors Corporation (PSC) was founded in 1996 by Tim Carey and Robert Winson who recognized an opportunity to better address customers' needs with a more reliable and repeatable moisture transmitter that was simple to install, at a competitive price point.

Coined with the initials “MT” for Moisture Transmitter, Tim and Robert introduced the MT-100 NIR Transmitter, the first truly standalone Near Infrared (NIR) moisture measuring device that included an integral central processor which eliminated interconnected cabling for ease of installation at production plants. In September, the first office and manufacturing plant was opened at 288 West Street, Milford, MA.


PSC on-line transmitters were soon being sold to major Fortune 500 companies such as Willamette Industries in the wood industry, and major tobacco processing companies within the US and Canada.


In 1998, the Multi-Constituent Transmitter (MCT) product line was developed which measured two constituents such as moisture and oil plus product temperature. This opened new opportunities in the food and snack food markets.


Continuing the quest to fulfill customer needs and broaden the markets served, PSC launched the world’s fastest NIR laboratory bench top transmitter, the MCT600. These transmitters are used near a factory production line or in a laboratory providing rapid, accurate validation measurements in under 10 seconds. Producers of crackers, chips and bulk powder products were then added to the growing list of customers.


PSC soon out grew the West Street facility and relocated to the current location at 113 Cedar Street, Milford, MA. Regional sales and service offices were opened throughout the US to better support the expanding customer base and seek new opportunities across many industries.

Also in 2001, PSC made the strategic move to pursue opportunities outside of the US by opening an office in Corby, UK with expanded manufacturing capability to serve the European market.


The Company’s first web scanner for the converting industry was introduced for real time moisture measurements where coatings such as adhesive are applied to paper or other substrates. This scanner evolved over time to what is now the Guardian Scanning Frame System, once again opening doors with new product technology that addresses critical customer needs in new industries.


The MCT330-SF Transmitter was introduced to measure moisture in snack food. With a stainless-steel housing, the MCT330-SF meets the standards required for food applications, withstands high temperatures and thorough wash down conditions needed when processing food.


In 2007, the organization again expanded into new markets, seeing new opportunities using Infrared (IR) technology for temperature applications in harsh environments. Process Sensors IR division was formed to provide customers with a broad selection of IR imaging and measurement products for a variety of new industries including steel, plastics, and power generation.


Further expansion into Eastern Europe was needed so an office in Warsaw, Poland was opened.


Expanding into additional technologies, the Radio Frequency (RF) product line was launched. RF measures moisture in products of a uniform density via magnetic wavelengths. Non-contact dielectric rays penetrate through products such as textiles, cardboard, plywood, hardwood and gypsum board. Customers are now able to control quality fast and accurately on line and in process. The RFM1000 on-line device was soon followed by handheld and bench top laboratory testers.


The MCT460 series of transmitters is launched, employing high performance dual core microprocessors and upgraded electronics/components to withstand vibration and other challenges found in harsh environments. The on-line and bench top testers’ dual core microprocessors are more stable, reliable and customizable for the customer’s specific application.


In September 2015, PSC become the second company to be acquired by KPM Analytics shortly after Unity Scientific.


Starting in April the Milford headquarters expanded and modernized to accommodate administrative and production activities for both the PSC and Unity Scientific operating companies, including a new state-of-the-art conference room for meetings and training.

In July, the KPM Asia Pacific sales office opened, expanding efforts alongside the KPM operating company, Chopin Technologies.

Unity Scientific headquarters officially moves to the Milford location in August.

In September, founder Tim Carey retires while Rob Winson continues with the business.


In June 2017, new R&D and Application Development laboratories opened in Milford to better solve our customer’s tough application requirements.


KPM Analytics HQ moved to the much larger Westborough location in June 2021.
