Abstract: PURPOSE: To obtain a highly accurate liquid sealed type differental pressure transmitter which compensates the static pressure errors at zero point of a pressure sensitive element without adding any mechanism at all by sealing liquids of respectively different rates of compression into a high pressure chamber and a low pressure chamber  
     CONSTITUTION: A pressure sensitive element 4 receives the external pressures respectively introduced from flanges 3a, 3b on its both sides by way of partition diaphragms and sealing liquids 7a, 7b and detects the difference of the both external pressures and outputs the same to an amplifier 10.
