Title: Minute-differential-pressure transmitter
Inventor: HOSHINO YUKIO
IPC: G01L9/00
Filed: 1983-07-18
Abstract: PURPOSE:To perform accurate temperature correction and to improve measuring accuracy, by arranging a central diaphragm and a pressure sensitive element in parallel in the direction of the radius of casings. CONSTITUTION:A central diaphragm 32 separates pressure chambers 35 and 35' in casings 31 and 31'. The diaphragm 32 and a pressure sensitive element 38 are arranged in parallel in the direction of the radius of the casings 31 and 31'. Thus the pressure sensitive element 38 and liquid contacting parts, i.e., pressure receiving diaphragms 33 and 33' are brought to close proximity. A temperature sensor enclosed in the pressure sensitive element 38 can detect the temperature of the contacted liquid accurately. Therefore, accurate temperature correction can be performed. The length of the pressure receiving direction of the casings 31 and 31' can be made short owing to the parallel arrangememt of the central diaphragm 32 and the pressure sensitive element 38. Therefore, slant errors and errors due to vibration and shocks can be made small. Thus the measuring accuracy can be improved.
