2.1. General Description

The PC-507-IS is a pressure calibrator designed to be used in hazardous areas where
there is presence of flammable or explosive vapors. It is an instrument of small dimensions,
compact; it operates with rechargeable battery and comes with a leather carrying case. Its
technical features indicate performance levels comparable only to laboratory standards; it
presents accuracy of 0.025% of full scale. Can be provided with one, two, three or four pressure
sensors. Thus, in a single calibrator may be have different pressure ranges, e.g. vacuum, 0 to
100 psi, 0 to 1000 psi and 0 to 3,000 psi, or any combination of available ranges. The calibrator
may be purchased with a certain number of sensors, which may be later increased. Designed
for field use, it contains useful items as a high contrast LCD for a better viewing in poor lighting
conditions, besides presenting measured and generated signals with large digits so that they
can be seen far away, rechargeable battery and large memory capacity to store the values
making it possible to transfer them to the PC, when necessary. Besides these, may be
mentioned several other constructive factors which add to the calibrator quality and efficiency,
including providing its use not only in the field as workbench.
It incorporates the most modern concepts of calibration via computer, where data
are shared between instrument and computer, improving efficiency in handling information
through report and certificate issues, automatic tasks management, data organization and
storage, for an overall coverage of quality procedure requirements, especially those related to
ISO 9000.
When connected to a computer it can be used for on-line data acquisition (only in safe
area).
