It operates on a 24VDC supply. It communicates via a 0-10 VDC analog output signal representing pressure. The transducer interfaces with vacuum control systems, data acquisition units, and vacuum chambers. Common applications include thin film deposition, and vacuum metrology. ## Function High-vacuum pressure measurement using hot cathode ionization gauge principle for measuring pressures from 10^-3 to 10^-9 Torr. Generates ion current proportional to gas density by electron bombardment from heated filament. Features dual filament design for redundancy, bakeable construction for UHV compatibility, and nude gauge configuration for fast response. Interfaces with gauge controllers via standard electrical feedthrough connections providing filament power, grid voltage, and ion current measurement. Commonly used in semiconductor processing, thin film deposition, mass spectrometry, particle accelerators, and surface science applications requiring accurate high vacuum monitoring. ## Platform Designed for high-vacuum (HV) and ultra-high-vacuum (UHV) systems. Mechanically interfaces with a vacuum chamber via a 2.75-inch ConFlat (CF) flange. Electrically connects to a compatible hot cathode ionization gauge controller via a 9-pin D-subminiature connector. The controller provides operating voltages and processes the ion current to determine pressure. System integration is achieved through the controller's analog or digital outputs for process control in semiconductor manufacturing, surface analysis, and thin-film deposition systems. ## Application Functions: Measures vacuum pressure via ionization of gas molecules. Operates from 1x10-10 to 1x10-2 Torr. Includes an integrated emission regulator and utilizes a hot cathode, typically a tungsten filament, for electron generation. \nHardware: Designed for use in vacuum chambers. Requires a regulated DC power supply and a dedicated controller for operation and signal processing.\nConnectivity: Provides vacuum pressure readings through an analog output signal (e.g., 0-10 VDC) and/or a digital interface (e.g., RS-232/485). \nApplications: Thin film deposition, vacuum coating, semiconductor manufacturing, research and development, and leak detection. ## Accessories Requires compatible vacuum power supply and controller for hot cathode operation; connects via coaxial cable with SMA connector; interfaces include analog output via BNC connector for pressure readout; requires vacuum fittings compatible with transducer flange (CF or ISO standard); calibration kit recommended for accuracy verification. ## Interface Vacuum connection is a 2.75 inch Conflat (DN40CF) flange. Electrical connection is a 9-pin male D-subminiature (DE-9M) connector. This interface provides +13.5 to +30 VDC power input, a 0-10 VDC logarithmic analog pressure signal output, and digital I/O for filament, degas, and status. Features a yttria-coated iridium filament. Requires a compatible controller for power and signal processing, and a DE-9F cable. ## Images - - - -
