Replacement E025 Pirani pressure gauge, part number 795706, for the PI1 position in compatible helium leak detectors. The source product record identifies aluminum as the principal material. Confirm the gauge range, electrical connection and instrument version before ordering.
Description
E025 Pirani Gauge, Part No. 795706
The E025 Pirani gauge is intended for pressure measurement in the PI1 position of compatible helium leak detectors. It monitors vacuum-system pressure using the thermal-conductivity principle and provides an input used by the instrument's operating and protection logic.
| Product type | Pirani pressure gauge |
|---|---|
| Reference | E025 / 795706 |
| Instrument position | PI1 |
| Principal material stated in source record | Aluminum |
| Application | Replacement gauge for leak-detector service |
A Pirani gauge derives pressure from heat transfer between a heated element and the surrounding gas. Correct gauge operation is important for vacuum sequencing and reliable leak-detector operation.
The source page does not state the measurement range, accuracy, connector or complete model list. Confirm the instrument model, serial number, gauge range, electrical interface and mechanical connection before ordering.
After installation, perform the gauge checks and leak-detector calibration specified in the applicable service documentation.
