|If there is a crevice finder
From air leak investigation of piping of a factory to an improvement of air conditioning efficiency
Pollen is not made to advance.
|It seems that it can contribute also to energy saving by that which can raise the efficiency of the air conditioning of a clubroom while preventing pollen and allergen trespassing upon a clubroom when the problem of earth environment maintains the confidentiality of the room these days which became subject. The air leak detector of our company not only detects the leak of piping etc., but is high performance as a crevice finder. Crevices, such as the door of a residence, a window, a refrigerator, a safe, a window of a car, and a case, can be investigated easily.|
An ultrasonic wave is transmitted from a supersonic transmitter towards the part considered that there is a crevice. A receiver detects an ultrasonic wave from the side opposite to, and the existence of a crevice is detected. The detected ultrasonic wave signal is changed so that man's ear may hear. According to the strength of an ultrasonic wave, it displays on a display for indication in digital one. If an ultrasonic wave signal is strong if a crevice is large, a crevice is small and an ultrasonic wave signal will not have a crevice weakly, an ultrasonic wave signal will not be detected.
|■Measuring method1 :
When [ of the door of a building, and a window ] conducting a crevice inspection
Supersonic transmitter COM-1011 is moved along with the sash of the door which inspects a crevice, and a window, and it goes. being the side opposite to, and hearing sound by headphone, moving the same position as a supersonic transmitter for the main part of ultrasonic receiver COM-1010 -- the number check of a display for indication -- it carries out. in a place with a crevice, the sound of an ultrasonic wave signal can be heard well -- the number of a display for indication -- it changes greatly.
■Measuring method 2:
When [ of a refrigerator, a safe, and the case of other 、 ] conducting an airtight inspection
Supersonic transmitter COM-1011 is put on the inside of a refrigerator, and it is 。.
From the outside, the seal portion of the door of a refrigerator is accompanied, the main part of ultrasonic receiver COM-1010 is moved, and it goes.
hearing sound by headphone -- the number check of a liquid-crystal-display machine -- it carries out.
in a place with a crevice, the sound of an ultrasonic wave can be heard greatly -- the number of a a display for indication -- it changes greatly.
