Active Gauges

• Simplified integration with a compact, rugged aluminum housing that mounts in any orientation with a logarithmic signal output
• Stainless steel sensor cell with metal-sealed feedthrough provides a rugged design for a wide range of applications
• Set-up is easy with push button ATM and High Vacuum (HV) adjustment
• Nickel filament option for applications in corrosive environments
• Optional set points allowing for the utilization of pressure readings to perform critical operations
