Johnson dropped a law practice to run a family business. After taking JMS Southeast through the recent downturn, the company gained recognition for thermocouple manufacturing, RTDs, and temperature transmitters.    The company has 100% sensor inspection (compliant with applicable MIL specifications as well as other industrial standards including those of ASTM, NIST, ANSI, and ISA) and ISO 9001 certification, with no-charge 24-hour customer service, and new NIST-traceable calibration program that complies with ISO 9000 / OSHA PM 1910. A rolling purchase order program has special volume and OEM discounts.

Non-work-related activity

Johnson is the father of two children, one born at 23 weeks. He led Team Will for March of Dimes, working with friends, neighbors, civic clubs, and family to raise $32,395, ranking ninth in the U.S. in fundraising.

Engineering-related activity

Johnson developed the JMS SwiftyCalc program for dimensioning thermowells for the process industries, to help ensure thermowell designs meet a revised 2010 standard that adds 40 pages of calculations. “Based on ASME PTC 19.3, SwiftyCalc has become the de facto world standard in just one year,” he said.

Interesting details

Johnson is co-authoring the book “Practical Thermocouple Thermometry” with Dr. Tom Kerlin. It is scheduled for publication with ISA this fall. Johnson is also a Paul Harris Fellow in the local Rotary Club.

Began interest

The Johnson family has been involved in the field for more than 35 years, and JMS was founded in 1980. “I have always wanted to participate and got the chance to do so four years ago. It has been a most rewarding and exciting experience.
