TH6021C3 - A functional tester, a device used to measure the difference between pressure - Google Patents

Abstract

A functional tester, a device used to measure the difference between pressure, consists of The mounting platform used to measure the difference between the pressure on one side has two threaded holes, and the other side that is not opposite to the side with the first 2 holes drilled. 2 holes, which are drilled perpendicular to the first 2 threaded holes, and have a set of devices to measure the differential pressure of the tool. Display the working condition of the electronic circuit. It consists of a normal operating lamp, closed with a normal operating lamp. That shows the work by the contact of the device used to measure the difference between the pressure that was tested. Inside of the unit is the function of the device to measure the difference between the pressure, there is an electronic circuit to show the action along the contact of the device. Consisting of a lamp showing normal operation, closed With a lamp showing operation, normal condition, open In which both lamps will perform operations by their contacts. Connected to the device used to measure the difference During the pressure that comes to be tested It is powered by built-in battery.
