PHYSICAL QUANTITY MEASURING DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

A circuit board including an electronic circuit unit and electronic adjusting units is disposed in a case. A signal transmitting member connected to the circuit board is mounted in a mount hole of a cover member. Operation holes corresponding to a plurality of operable portions of the electronic adjusting units are provided to the cover member. A cap member including a plurality of cap bodies and a connection portion connecting the cap bodies is attached to the cover member to close the operation holes. The operation holes for adjusting the electronic adjusting units are thus covered/uncovered by the simple cap member. The operation holes are reliably waterproofed by the cap member.

主权项

1. A physical quantity measuring device comprising:
a cylindrical case having a first open end and a second open end; a detector provided to the first open end of the case to detect a physical quantity of a fluid to be measured; a cover member attached to the second open end of the case; a circuit board disposed in the case, the circuit board comprising:
an electronic circuit unit configured to detect a detection signal from the detector; andan electronic adjusting unit configured to adjust the electronic circuit unit, the electronic adjusting unit comprising a plurality of operable portions; a signal transmitting member mounted on the cover member and connected to the circuit board, the cover member being provided with a mount hole for mounting the signal transmitting member and an operation hole allowing the plurality operable portions to be operated to adjust the electronic adjusting unit; and a cap member provided to the cover member to cover the operation hole, the cap member comprising:
a plurality of cap bodies removably attachable to the operation hole; anda uniting portion configured to unite the cap bodies.
