Electronic transformers are transformer used in electronic applications. These are used to supply power, transmit signals, and establish voltage isolation between circuits, sense voltage and current levels. It also provides impedance matching, and filtering. The types of electronic transformers include power, pulse, instrument, and current, switching, inverting and impedance matching transformers.
Electronic Vacuum Sensor is capable of detecting a relatively low vacuum pressure of about 0.04 to 0.05 inches of water. The power source is coupled to the contact blade. The LED is activated by a high-sensitivity vacuum switch. A thin flexible diaphragm extending longitudinally through the channel between the second contact blade and the lower surface of the channel. The pressure travels along the diaphragm and raises the diaphragm.
