{"title":"Edwards Vacuum Gauges","description":"\u003cp\u003eAccurate pressure measurement is what turns a vacuum system from guesswork into a controlled process. Gauges tell you when a chamber is ready, when a pump is wearing, and when a leak has appeared. Edwards has supplied vacuum gauges and gauge controllers for decades, and many Edwards pumping systems are designed to work with Edwards active gauges and TIC instrument controllers. At Provac Sales, we list Edwards measurement and power equipment and help customers source the Edwards gauges and controllers their systems need.\u003c\/p\u003e\n\n\u003ch2\u003eWhat We Currently List\u003c\/h2\u003e\n\u003cp\u003eOur Edwards vacuum gauge collection currently includes:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003eEdwards iPS-240 power supply, new, rated for 100-240V at 50\/60Hz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe iPS-240 is also listed in our turbo pump controller category.

Choosing the wrong type is one of the most common causes of misleading readings.\u003c\/p\u003e\n\n\u003ch3\u003ePirani Gauges\u003c\/h3\u003e\n\u003cp\u003ePirani gauges measure pressure by sensing how quickly gas carries heat away from a heated wire. They are inexpensive, robust and well suited to rough vacuum, roughing lines and foreline monitoring. Their readings depend on gas type, so they are usually calibrated for nitrogen or air.\u003c\/p\u003e\n\n\u003ch3\u003eInverted Magnetron Gauges\u003c\/h3\u003e\n\u003cp\u003eInverted magnetron gauges ionize gas in a magnetic field and measure the resulting current. They suit high vacuum measurement and have no hot filament to burn out. Like Pirani gauges, their readings depend on gas type.\u003c\/p\u003e\n\n\u003ch3\u003eWide Range Gauges\u003c\/h3\u003e\n\u003cp\u003eWide range gauges combine two sensors in one head and switch between them automatically. One gauge can cover a whole pump-down cycle, which saves ports on small chambers and simplifies wiring.\u003c\/p\u003e\n\n\u003ch3\u003eCapacitance Manometers\u003c\/h3\u003e\n\u003cp\u003eCapacitance manometers measure the deflection of a thin diaphragm under pressure. They are gas-independent and highly accurate, which makes them the preferred choice for process control where gas composition changes, such as deposition and etch.\u003c\/p\u003e\n\n\u003ch3\u003eStrain Gauges\u003c\/h3\u003e\n\u003cp\u003eStrain gauges measure pressure near atmosphere independently of gas type. They are useful for venting control, backfill and load lock monitoring.\u003c\/p\u003e\n\n\u003ch2\u003eHow to Select an Edwards Gauge\u003c\/h2\u003e\n\u003cp\u003eBefore choosing a gauge, consider:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003eThe pressure range you need to measure, from atmosphere to your lowest working pressure\u003c\/li\u003e\n    \u003cli\u003eWhether readings must be independent of gas type\u003c\/li\u003e\n    \u003cli\u003eRequired accuracy and repeatability for process control\u003c\/li\u003e\n    \u003cli\u003eFlange type and size, such as KF16, KF25 or CF\u003c\/li\u003e\n    \u003cli\u003eController or display compatibility, including the cable and connector\u003c\/li\u003e\n    \u003cli\u003eOutput signals needed for your control system, such as analog voltage or setpoint relays\u003c\/li\u003e\n    \u003cli\u003eEnvironmental factors, such as contamination, vibration or bake-out temperature\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIf you are replacing a gauge, the model number on the gauge head and the controller it connects to are usually all we need.\u003c\/p\u003e\n\n\u003ch2\u003eGauges and Controllers Work as a System\u003c\/h2\u003e\n\u003cp\u003eAn active gauge contains its own electronics and sends a signal to a controller or display. The controller supplies power, converts the signal to a pressure reading and may provide setpoint outputs for interlocks. Edwards TIC instrument controllers can read several active gauges and also control a turbo pump, which keeps a small system tidy.\u003c\/p\u003e\n\u003cp\u003eWhen ordering, confirm that the controller supports your gauge type and that you have the correct cable. A gauge that reads incorrectly is often connected to the wrong controller input or set to the wrong gas calibration rather than faulty.
