Official definition
This U.S. industry comprises establishments primarily engaged in manufacturing instruments and related devices for measuring, displaying, indicating, recording, transmitting, and controlling industrial process variables. These instruments measure, display or control (monitor, analyze, and so forth) industrial process variables, such as temperature, humidity, pressure, vacuum, combustion, flow, level, viscosity, density, acidity, concentration, and rotation.

Which code does this activity belong in?
Code 334513 covers establishments manufacturing instruments that measure, display, and control industrial process variables such as temperature, pressure, flow, and viscosity. The boundary separates this code from 334512, which covers automatic controls for residential and commercial heating, air-conditioning, and appliances rather than general industrial process monitoring. Code 334513 also differs from 334516, which classifies analytical laboratory instruments used to analyze chemical composition of samples, whereas 334513 instruments monitor ongoing industrial operations rather than perform compositional analysis.
