Abstract
PURPOSE: To achieve the higher reliability of the electronic type liquid level and liquid volume gauge by allowing static electricity being charged to electrodes to normally discharge, announcing the stop of the sensor function with a warning lamp and letting the pulse transmission between the electrodes be effected through contacts.
CONSTITUTION: Ground resistors are connected to respective electrodes to allow the static electricity to be going to be charged in the electrodes to discharge, whereby the electrostatic breakdown of the semiconductor elements of scanning circuits is prevent ed. In addition, the circuits for announcing the abnormality with a warning lamp when the function of the sensor has ceased or the liquid level to be measured has lowered below the effective measuring range owing to trouble are provided. These are so constituted that the scanning pulses are applied to the electrode plate A of 2 and are read out from the electrode plate B of 3, by which the position of the electrode plate A where the contact 5 fixed to a float 6 contacts is known and the data may be outputted as pulse trains. Sucn constitution enables the reliability of the electronic type liquid level gauge to be improved.
