B2A 1*10-3 to 20 Torr Portable Vacuum Controller

Part Number: 2-3001-100

The Televac B2A Portable is a small, battery-powered, portable vacuum controller (also called a vacuum control unit, vacuum pressure controller, or digital vacuum gauge). It’s designed for use with Televac 2A thermocouple gauges (Pirani). This vacuum pressure controller has a range of 1*10-3 Torr (1 micron) to 20 Torr (20,0000 microns) and an analog display (sweeping needle) that reads in microns (mTorr).

The portability of this vacuum controller makes it ideal for cryogenic and industrial gas applications where the vacuum controller needs to be carried to different (sometimes mobile) tanks to take vacuum measurements of their vacuum insulation or vacuum jacket. The B2A Portable has an analog display (sweeping needle), but if you’re looking for a portable vacuum controller with a digital display, we also have the VacuGuard portable vacuum controller.

VacuGuard – The VacuGuard is a small, portable instrument designed for use with Televac 2A thermocouple or competing DV-4 and DV-6 series thermocouple sensors. The VacuGuard is powered by a 1.5 V D cell battery and will accept either single-use or rechargeable batteries. Front-panel controls consist of a toggle power switch and a three-position sensor select switch. The digital display is a four-digit, seven-segment, 0.6” high, red LED protected by a grey neutral density filter making the display easy to read in bright ambient conditions. At 23 ounces, this lightweight instrument has a small size of 4” x 2.5” x 5.5” and can read from 1×10-3 Torr to 20 Torr.

MX2A Active Gauge – The MX2A utilizes an easily replaceable Televac 2A thermocouple vacuum sensor. It has a variety of features including a wide range of measurement from 1 × 10-4 Torr up to 1000 Torr, RS-485 communications, two programmable set points, and a selectable analog output. The bright OLED display makes it easy to read from a distance. Options can be set from four capacitive touch controls located on the top of the unit or through RS-485 communications. The extensive selection of fittings, simplicity of use, ease of sensor replacement, and competitive cost make this unit an excellent choice for a variety of vacuum applications.

While portable vacuum controllers are the best vacuum controller option for some applications, other applications are better suited for a rack/panel mountable vacuum controller or an active vacuum gauge where the electronics head is connected directly to the passive vacuum gauge (instead of with a cable).

If you’re interested in a rack/panel mounted vacuum controller, a good place to start is the MX200. If you’re interested in an active vacuum gauge, check out the MX4A for low vacuum measurement (10-3 to 1000 Torr) and the MX7B for high vacuum measurement (10-8 to 10-3 Torr).
