Active Gauge Selection Chart

Agilent Vacuum Active Gauges integrate the gauge and controller in a single, compact package. These are ideal for embedded OEM and industrial systems where a control computer or PLC handles the display/control functions for one or several gauges. The user provides input power (typically 24V) and reads pressure output via PC or PLC. A variety of set point interface features are available to automate your system.

Vacuum Range	Gauge Type	Gauge Characteristics
Rough Vacuum - Atmosphere to 10-³mbar
	PVG-500 Micro Pirani Gauge	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 Push button ATM and High Vacuum (HV) adjustment is easy to set-up Nickel filament option provides a solution for corrosive applications Optional set points use pressure readings to trigger critical operations
	CDG-500 Capacitance Diaphragm Gauge	Full scale ranges from 1 to 1000 Torr with push button zeroing and optional set point control Excellent long term signal stability and repeatability deliver long term performance comparable to heated versions Fast recovery from atmospheric pressures and rapid stabilization after start-up reduces process cycle times Corrosion resistant ceramic sensor with sensor shielding protection
	PCG-750 Pirani/Capacitance Diaphragm Gauge	High accuracy and reproducibility at atmosphere Fast atmospheric detection shortens process cycle times Gas-type independence above 10 mbar allows safe venting with any gas mixture Compact, rugged housing that mounts in any orientation with a logarithmic signal output Set point control uses pressure readings to trigger critical operations Exchangeable plug and play sensor is easy to repair and lowers cost of ownership Nickel filament option provides a solution for corrosive applications Bright color LCD display option makes pressure easy to monitor
Full Range Gauges - Atmosphere to 10-¹⁰ mbar
	FRG-700/702 Pirani/Inverted Magnetron Gauges	Provides two measuring technologies in a single, compact, economical package Measures process and base pressure from 5 x 10-⁹ mbar to atmosphere (3.8 x 10-⁹ Torr to atmosphere) A single, compact unit with one logarithmic analog output signal significantly reduces complexity of installation, setup and integration Ideal for high vacuum pressure monitoring, base pressure for evaporation and sputtering systems, and general vacuum measurement and control in the medium and high vacuum range Wide measurement range from 5 x 10-⁹ mbar to atmosphere No filament to burn out Excellent ignition properties Easy to clean
	FRG-720/730 Pirani/Bayard-Alpert Gauges	Combination gauge – Bayard-Alpert and Pirani provides a wide measurement range from 5 x 10-10 mbar to atmosphere Long-life yttrium oxide coated iridium filament provides a rugged design for a wide range of applications Pirani interlock protects Bayard-Alpert sensor from premature burnout and contamination effects from high pressure operation Set point control uses pressure readings to trigger critical operations LCD display option makes pressure easy to monitor Profibus communication option allows easy network integration
