IE414, IE514 Thermal Ionization Vacuum Gauge

IE414, IE514 Thermal Ionization Vacuum Gauge

IE414 and IE514 are vacuum sensors based on the hot cathode ionization effect. IE414 is a Bayard Alpert vacuum gauge, while IE514 is based on the principle of a vacuum pump. These passive vacuum gauges are combined and controlled by the IM540 vacuum gauge controller.

By adjusting the cathode emission current, the measurement range of IE414 ranges from 10-2 millibars to 10-11 millibars, spanning over 9 divisions. Due to the use of the extractor principle, IE514 can achieve a measurement lower limit of 2 × 10-12 mbar, thanks to its own reduction of X-ray and ion desorption effects. The IE414 and IE514 vacuum gauge heads are designed specifically for low-pressure vacuum systems and can be baked at very high temperatures (400 ° C). The high-temperature resistant vacuum gauge head cable kit can also be used for high-temperature baking exceeding 200 ° C (250 ° C at the sensor flange).
