Measuring instruments and sensors

Common to almost all applications is that we need to know what process pressure we have. Therefore, we need to use measuring instruments and sensors that help us to transmit and convert electrical signals (in most cases) to understandable numbers.

Vacuum sensors are available in many variants and for different purposes.

• Pirani
• Manometer
• Cold cathode
• Hot cathode
• Monetary
• Combination sensor
• Extractor

The most common are the Pirani sensor and the classic manometer. You can read more about each sensor on each page.

The instrumentation itself looks very similar today, it is often a display with numbers and various settings. Some support simple calculations and self-tests, others simply show only the value measured by the sensor. You will find our instruments together with the donor who envisioned you. If you do not know which one you have, contact us and we will help you.

Knowing what process pressures we have may be a necessity for the result to be as we intended, it may be an indication that the system is leaking, it may indicate that the pumps being used are in poor condition and may need servicing. But perhaps the most important thing is security. Just as with overpressure, awareness of the pressure in vacuum is also important for safety reasons. Therefore, it is also important to know that the donors you rely on actually show the right, or that you know its deviations. Low2High Vacuum therefore recommends that all customers continuously have their sensors calibrated to find out exactly this. We believe quality and safety are important and therefore recommend calibration.
