AN EXTRA MEASURE OF ACCURACY

All W&T Portable Pneumatic

Calibrators are subjected to rigo-

rous and extensive testing. Each

has to perform at bet

ter than the

rated accurac

y to be accepted.

It’s accurate enough to double

as a shop standard.

Calibration traceable to NBS

Calibration is with primary stan-

dards

which are directly trace-

able to the German National

Bureau of Standards (PTB).

DESIGN AND CONSTRUCTION

The Series 65-120 Portable Pneumatic Calibrator is a

pressure-vacuum test stand wholly contained in a

carrying case. The front panel accommodates the

precision pressure gauge, all pressure connections,

two air-regulator controls, and a selector valve. With

the selector valve, three different test pressures can

be applied individually to the gauge. A fourth selector

setting vents the gauge to atmosphere.

The precision pressure gauge has a Ni-Span C, cap-

sule-type pressure element which gives excellent

temperature stability and speed of response. An

almost frictionless mechanical linkage amplifies

capsule movement and transmits it to the pointer.

Although highly sensitive and accurate, the mecha-

nism is built to withstand the handling normally as-

sociated with on-site calibration of pneumatic instru-

mentation.

A filter on the air supply keeps oil and moisture out.

Two regulators apply known pressures to the devices

under test. The connection block has

-inch female-

pipe-threaded connections. Small gauges can be

threaded directly into the block; or as with larger

instruments, connected by flexible tubing.

The standard scale contains two sets of calibrations:

–100 to 0 to 850 inches of water and –3.6 to 0 to

30.6 psi.

Other ranges and units of calibration (from min.

0–4,5 psi

to max. 0–100 psi) are available.

The Series 65-120 Pneumatic Calibrator provides high-degree accuracy

for on-site testing and calibration service. This versatile portable test

stand combines precision measurement and durable construction in a

compact unit that is capable of simulating, applying, holding, regulating

and measuring both pressures and vacuum. The dial, all pressure connec-

tions, and the controls are panel-mounted for easy access.
