What does SensorCatalog do?
SensorCatalog is a collection of free browser-based sensor calculators and reference tables. It helps users convert 4–20 mA signals, calculate PT100/PT1000 resistance and temperature, estimate RTD lead-wire error, and check current-loop voltage budgets. Tool pages explain formulas, units and input assumptions. Results are calculation aids and should be checked against equipment documentation and installation requirements. Submitted by Walter Chen, the site maintainer. SensorCatalog includes disclosed sensor-inquiry links to SensorSpan.
