Download Datasheet

Part Numbers: 2-2100-102, 2-2100-102-01, 2-2100-045

Compatible With: MX200, MX200 EthernetIP, MV2A, Compact 2A, VacuGuard™, B2A Portable

Features and Benefits:

  • Compact, robust, contamination resistant vacuum transducer
  • Standard Pirani 1/8″ NPT flange/fitting
  • Weather capped vacuum transducer with gasket and tether
  • Drop-in vacuum pressure gauge replacement
  • Excellent customer support for vacuum transducers
  • Convection gauge filters available for highly contaminated environments

The Televac® 2A VacuMini is a commercial version of Televac®’s highly successful NASA 2A gauge. Our 2A VacuMini thermocouple vacuum gauge tube (also often called a Pirani or vacuum pressure gauge) is widely considered our most robust and contamination resistant low vacuum pressure gauge due to the Pirani filament design and operating temperature, and it’s simple to install because it can be mounted in any orientation.

The 2A VacuMini is roughly half the size and volume of traditional thermocouple vacuum gauge tubes. This thermocouple vacuum gauge’s primary limitation is that with all of our vacuum controllers, this thermocouple vacuum transducer will only read from 1*10-3 Torr (1 micron) to 20 Torr (20,000 microns), instead of all the way up to atmosphere (760 Torr).

This vacuum gauge also has slightly reduced accuracy over some parts of its operating range when compared to the 4A convection vacuum gauge. The 2A VacuMini vacuum pressure gauge can be operated by several Televac® controllers, including the MX200, MX200 EthernetIP, B2A Portable, Compact 2A, VacuGuard™, and MV2A.

Applications

The VacuMini is ideally suited to applications where the vacuum vessel is located outdoors or in a physical environment that renders use of traditional thermocouple sensors impractical. Examples of such applications include:

  • Fixed and mobile bulk cryogenic storage and transport vessels
  • Vacuum jacketed gas delivery manifolds
  • Mechanical vacuum pumps and blowers
  • House vacuum systems
