摘要: A disposable pressure transducer for measuring fluid pressure, which includes a sensor assembly in a housing. The housing includes a fluid chamber and a sensor-accommodating chamber which are formed integrally with each other. The sensor assembly comprises: a sensor chip for converting pressure into an electrical signal; an insulating board on which the sensor chip is mounted and which is provided with an integrated-circuit for processisng an output signal of the sensor chip so that an external measuring device can read the signal; a cylindrical coupling lid which is bonded to the board in such a manner as to surround the sensor chip and which is fitted into a communication through-hole which provides communication between the fluid chamber and the sensor-accommodating chamber of the housing; a pressure-transmitting medium charged into the interior of the coupling lid so as to provide electrical insulation between the fluid chamber and the sensor chip; and an electrical cable connected to the board and electrically connected to the external measuring device.
