<p>PURPOSE: A pressure detector is provided to prevent the generation of a dead space on a through-hole, thereby detecting pressure with high precision. CONSTITUTION: A pressure detector includes a body (16), a sensor chamber (34), and a through-hole (30). The body has a flow path (28) in which a fluid flows. A pressure sensor (18) at the body is installed in the sensor chamber. The through-hole is extended from the flow path to the sensor chamber. A pressure transmitting body (32) is installed in the through-hole. The position of the pressure transmitting body is freely varied along an axial direction. The pressure transmitting body transmits the pressure of the fluid to the pressure sensor. One end of the pressure transmitting body is extended from the through-hole to the end of the flow path, and is always exposed to the fluid.</p> |
