The current sensor is a sensor to measure the current as its name. However, The current is various. There is a current value up to 10k amperes treated in the power plant from 1mA, and the shape of current waves also has AC, DC, and AC + DC. Since a method and a structure the best in each measuring object are different, there are also various current sensors. Tamura supplies the sensor using ...

A leakage in mining ponds also means loss of product through geomembrane damage which can be as much as $500,000/ha/annum. To avoid this, testing of geomembrane integrity using SENSOR DDS ® technology should be carried out pre and post covering and throughout its service life to …
22/05/2019· LPG sensor (MQ-6) output voltage is fed to inverting pin 2 of IC2. If reference voltage (pin 3 of IC2) is less than sensor voltage (pin 2 of IC2), output goes low, which means there is no LPG leakage. With low output, T1 remains cut-off and there is no current flow through the buzzer; it does not sound and remains in silence mode.
