DESCRIPTION

The SI-BARNET 6000L range of Pneumatic Deadweight T esters provide reliable primary standards
of PRESSURE and VACUUM for use in all calibration environments.

The tester consists of a precision piston / cylinder (PCU) assembly of known effective area mounted
onto a rigid aluminium baseplate. Stainless Steel weights of known mass are mounted onto the
PCU assemblies and are balanced by either pressure or vacuum (generated by integral pump)until
they "float" and spin freely thus generating a known pressure. A pressure gauge to monitor system
pressure and control valve to adjust and release pressure are mounted to the case. The DWT can be
levelled by means of four adjustable feet and a spirit level.
The set of non-magnetic weights is conveniently stored on the case and the tester comes complete
with a set of "quick-fit" adaptors and seals for easy mounting of the items under test to the
Deadweight T ester.

A list of standard and optional accessories is shown in Table 2. Page 7.
There are basically two models available :­MODEL 6000L ... PRESSURE ONLY

See Table 1. below for pressure ranges and model numbers.

MODEL 6100L … VACUUM CONVERSION KIT. CONVERTS MODEL 6000L FOR VACUUM
USE.

CAUTION, TO A VOID DAMAGE TO INSTRUMENTS UNDER TEST :-

1. DO NOT apply positive pressure to a Vacuum instrument.

2. DO NOT apply vacuum to a positive Pressure instrument.
