The core of pressure sensor selection is mapping process requirements to a specific sensing principle. Step one: define the measurement type (absolute / gauge / differential / vacuum). Step two: determine the range and media characteristics. Step three: choose the sensing principle (strain gauge / piezoresistive / capacitive / piezoelectric). Step four: match the output signal (4-20 mA / HART / IO-Link) and explosion-proof rating (ATEX / IECEx). See the full guide at Pressure Sensors Complete Guide.

Bridge CMMs suit precision parts under 0.5 x 0.4 x 0.4 m with positioning accuracy down to 0.8 um. Gantry CMMs handle parts over 1 m such as chassis and mold inspection. Articulated arm CMMs trade accuracy for flexibility, ideal for on-site spot checks. Hexagon GLOBAL S, ZEISS PRISMO, and Renishaw Equator represent each tier.

SIMATIC S7-1500 dominates European chemical and pharma ecosystems. Mitsubishi MELSEC iQ-R leads in Japan/Korea supply chains and automotive OEMs. Allen-Bradley ControlLogix 5580 is prevalent in North American discrete manufacturing. The key selection factor is the existing field protocol (PROFINET / CC-Link IE / EtherNet/IP) and spare parts support.

Electromagnetic flow meters only work with conductive media at conductivity above 5 uS/cm (tap water, wastewater, acids and alkalis). For non-conductive fluids (oil, ultrapure water, gas), switch to Coriolis or vortex meters. Endress+Hauser Promag 800, ABB ProcessMaster FEP630, and Yokogawa ADMAG are mainstream in chemical and water treatment applications.

Work backward from the load inertia ratio to determine the motor rated torque (recommended inertia ratio of 5 or less), then size the drive by peak torque. For low-inertia, high-dynamics applications use Yaskawa Sigma-7 or Panasonic MINAS A6. For high-rigidity, heavy-cutting use FANUC alphai or Siemens SIMOTICS S. Pay attention to encoder resolution and control cycle matching.
