Vacuum Magic: Houdini’s Guide to How A Vacuum Gauge Regulates Pressure Understanding how a vacuum gauge regulates pressure can be a mystery. Watch Nicole, as she demonstrates vacuum pressure regulation using a digital vacuum controller, balloon, and glass jar. Before our experiment, let’s review some vacuum vocabulary: Vacuum controller: a device that is used to maintain pressure for a period of time. The method of vacuum regulation used is called downstream pressure control. Set point: the targeted vacuum value the user wishes to maintain. In our experiment, the set point is chosen and the switch is turned to regulate (on). The
Safety 1st: Benefits of Using a Vacuum Gauge to Perform a Leak Test When troubleshooting an HVAC system, using a micron vacuum gauge (that has on board analytics) as a leak test is a safe way to assess why the system is not performing. A common problem in vacuum systems is that they are wet and have contaminants. Using a vacuum gauge enables you to determine when your system is dry, without damaging it. Vacuum testing is safer than pressure testing (implosion vs. explosion). The last thing you want to do is damage the HVAC system and be responsible for
You are on a service call, its hot, your wife’s calling AGAIN and you are behind! You’ve got to figure this one out quickly. Are there moisture and contaminants are in the system? Is the pump functioning properly?
