Analog Pirani Gauges
Analog Pirani Gauges version with sensors have a wide range of application in vacuum systems, coaters, sputtering systems and much other application when vacuum to be measured in the range of 0.5 to 0.001 bar.
Operating Principle:
- Within limits, decreasing pressure causes decrease in particle density, increase in their mean free path and lowering of the thermal conductivity of the medium, Pirani gauge heads, and gauge use this principle for system pressure measurement.
- The change in Resistance due to temperature build-up of a coil filament supplied with temperature build-up of a coil filament supplied with a constant voltage placed in a wheat stone bridge configuration, consequent to the pressure and thermal conductivity decrease is directly ready by the gauge.
- The gauge consists of the stabilized power supply and the indicating meter with the arrangement to select any of two gauge head consists of the bridge and calibration elements, these heads are factory calibrated with full interchangeability in the field.
Other Details:
- Totally indigenous
- Compact solid-state electronics
- Engineered for total reliability
- Two gauge head drive compatibility
- Minimum controls
- Wide angle meter for unambiguous indication
- No user calibration
- Modular hardware
- Ideal for roughing, fore line pressure monitoring
- Compatible output for pressure setpoint controller
