Vacuum gauges: Vacuum gauges are used to measure the pressure or negative pressure of non-crystalline, non-solidified liquids, gases or steam media that are non-corrosive to steel, copper and copper alloys and that are not explosive. Anti-vibration vacuum gauge table for vibration and pressure fluctuations, the measurement of non-corrosive, non-crystalline media negative pressure. Electric contact pressure vacuum gauge and electric contact vacuum gauge is used for the measurement of (pressure) and negative pressure of non-corrosive effect of copper and copper alloy without explosion, non-crystalline, non-solidified liquid, gas and the like when the pressure reaches the predetermined Value, with the help of contact devices, can be connected to or disconnected from the control circuit, while sending electrical signals. |
