Title:
感知センサ及び濃度測定器
Document Type and Number:
Japanese Patent JP4439500
Kind Code:
B2
Abstract:
An object of the present invention is to enable a user, when measuring a sensing target substance in fluid using a crystal sensor (sensing sensor) using a crystal vibrator whose natural frequency is varied by an absorption of the sensing target, to easily and accurately grasp information peculiar to the crystal sensor, for instance, information regarding a quality thereof. As a concrete means for solving the problem, it is designed such that an IC chip in which the information peculiar to the crystal sensor is stored is provided to the crystal sensor, and the peculiar information is read out at a side of a concentration measuring device when the crystal sensor is inserted into the concentration measuring device, and then displayed. The peculiar information is, for instance, information for guaranteeing the quality, and a concrete example thereof is information on a manufacturer, a serial number, a date of manufacture, a sell-by term, or the like, and further, the peculiar information may regard the sensing target sensed by the crystal sensor, and still further, it may regard a concentration standard value of the sensing target, or the like.
