Title: Process instrumentation rack
Inventor: ONODERA KOICHI
IPC: G01L27/00
Filed: 1992-11-30
Abstract: PURPOSE:To shorten calibration work time and improve accuracy by eliminating draining and the like, loading reference pressure for calibration to sensors during calibrating sensors for measurement, and calibrating at the same static pressure as actual measurement. CONSTITUTION:In calibrating a pressure sensor 1, high and low pressure side main valves V1 and V2 are closed and equalizing pressure valve V3 is opened to equalize the pressures at high and low sides of the sensor 1 so that the output becomes 0 in 0 point calibration. In other words, owing to the closing of main valves V1 and V2, the static pressure is transmitted to the sensor 1 as it is, and owing to the opening of the main valve V3, pressure signals become PH=PL, and thus, adjustment is executed in static pressure so that the sensor output becomes 0. Then, a main valve for calibration V6 is opened, 100% reference pressure for calibration is added from a reference pressure generator 2 and span control is executed so that the sensor 1 output becomes 100%. If necessary, a representative point between 0 and 100% is adjusted and output control, calibration in other word is done. In this case, the reference pressure is faithfully transmitted to the sensor 1 via the mother valve V6 and a pressure adapter 3. By this, only by adding a reference pressure, calibration is executed and draining and ice filling are avoided.
