Proportioning probe
| Глоссарий по тестированию |
Probe that can vary the tracer gas concentration in the sample at the sensor, typically by mixing pure air with sample gas from the probe inlet port. ratios of mixture between 100 percent pure air (obtained from an outdoors source or by filtering ambient air through charcoal) and 100 percent leak sample gas are attainable without great changes in total flow from the probe. the proportioning probe used in halogen leak testing lets the user operate in an atmosphere with up to 1000 ?l/l tracer gas background contamination. it proportions the amount of atmosphere allowed to enter the probe with its own (recirculating) fresh air supply. pump, adsorption: pump that creates a vacuum by collecting gas on the interior surfaces of the pump. pressures of 2 pa (20 ?bar) are readily attained. the pump has a finite capacity but may be regenerated for additional use. see also backstreaming; baffle. pump, cryogenic: pump that condenses chamber gas on a cold surface of 4 to 80 k (–269 to –194 °c). cooling is provided by liquid gas such as liquid helium or by refrigeration. see also backstreaming; baffle. 748 glossary p-r pump, diffusion: high vacuum pump with no moving mechanical parts that uses a vapor jet to sweep gas from the vacuum chamber and achieve pressures as low as 1 npa (10 ptorr). pump, displacement: mechanical pump that physically sweeps gas out of a volume and creates a vacuum. rotary piston and rotary vane pumps are two examples. a displacement pump can achieve pressures in the 0.1 to 1.0 pa (10 to 1 mtorr) range. see also backstreaming; baffle. pump, fore: mechanical pump in a helium mass spectrometer that performs initial evacuation of a system to a pressure of 0.1 pa and then accepts the exhaust from the high vacuum pump such as a diffusion pump. the forepump lowers pressure to less than 10 kpa into which the diffusion pump can exhaust its gas. pump, ion: pump that combines electric and magnetic fields to ionize gas and trap the gas inside the pump, thus removing it from the vacuum chamber. see also ionization gauge. pump, mechanical: mechanical device with pumping fluid and seals that physically removes a portion of the gas from a system with each revolution of the armature. a mechanical pump can pump a chamber down to about 0.1 pa (0.75 mtorr). see also gas ballast; roots blower. pump, sorption: pump consisting of a sieve and liquid nitrogen with ability to pump to 0.1 pa (1 mtorr). pump, turbomolecular: molecular turbine that drives gas out of a vacuum chamber, achieving a high vacuum pressure in the 10 npa (0.1 ntorr) range.
