Isolation Valves

To decrease the frequency

of zero adjustment, it is

recommended that a simple

manual or air-actuated bellows-

type isolation valve, such as

MKS Part No. 108818 (NC11

Cleaned), be installed between

a low range absolute sensor head and the processing

system.

Bellows Adapters

Frequently it is desirable,

because of mechanical

configuration or system vibration,

to attach the Baratron sensor

to the processing system using

flexible bellows couplings. All

flexible tubing is 321 stainless

steel, 1/4” diameter, and available in 6” and 12” active

bellows lengths. The use of flexible bellows minimizes

thermal expansion effects on sensor zero induced by hard

plumbing to the system.

Rack Mounts

The RM-6 Rack Mount Kit is used to adapt any half-rack

instrument (3 1/2” x 9 1/2”) to full-rack size (3 1/2” x 19”).

274B Three-channel Sensor Multiplexer

The 274B provides operation

of one, two, or three high

accuracy sensors with a single

670 Electronics Unit. The 274B

provides heater power for

temperature-controlled sensors

(690, 698). All sensors are kept

warmed up and ready for reading by the 670. The 670 can

sequentially read any one of the sensors, as selected by

a switch on the 670’s front panel, or by a remote ground

closure.
