Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not California. They belong to that state's ranking, not this one.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best suppliers of industrial sensors in California”
2“Who supplies high-accuracy temperature sensors with sanitary process connections in California”
3“I need a California industrial sensor partner for automating a food processing line, who should I talk to”
4“Top industrial sensor suppliers in California for plant engineering buyers”
5“Which California industrial sensor specialists can integrate flow, pressure, and temperature transmitters into an existing control system”
6“List 20 industrial sensors companies in California with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
