Instrument Accuracy Specs: pressure_transmitter
Accuracy, range, and performance specifications for process measurement instruments. Covers pressure transmitters (standard, high-accuracy, economy), differential pressure transmitters, temperature transmitters (RTD, thermocouple), flow meters (magnetic, vortex, Coriolis, ultrasonic, turbine), level transmitters (radar, GWR, ultrasonic, DP), pH analyzers, conductivity analyzers, dissolved oxygen sensors (amperometric, optical), and turbidity meters. Each record includes accuracy (% span or % reading), repeatability, turndown ratio, response time, ambient/process temperature range, max pressure, output signal, SIL rating, and MTBF. 28 records from Emerson, E+H, Yokogawa, Siemens, and Hach instrument datasheets.
