1.1. General Description

The Advanced Pressure Calibrator PCA-570 has levels of performance only comparable to laboratory
standards, having accuracy from to 0,025 % of full scale. It allows the measurement of several pressure ranges, as
well as the measurement and generation of volt and mA signals. It is designed to offer the necessary resources in
order to facilitate the work of keeping the process instruments adjusted and calibrated.
Its construction considers the use in the field, includes items of great value as: Bag with shoulder strap
allowing freedom for hands, 5.7" display with backlight led facilitating visibility in environments with little lighting,
rechargeable battery and large memory capacity to store the values obtained allowing their transfer to the
microcomputer when necessary. Besides these, several factors can be cited constructive which aggregate quality
and efficiency to PCA-570, including predict your utilization not only in field as also in rack (Version RM – Rack
Mounting, Version DT – Desktop).
Incorporates to most modern union concepts such as adjustments and calibrations with informatics, where
the data are shared by both the instrument and the computer, giving efficiency to the treatment of information, in the
form of emission of reports and certificates, of the automated management of tasks and of the organization and
archiving of data, that is, it covers a whole context directed to the fulfillment of quality procedures, mainly related to
the ISO-9000 standard. It also has HART
devices that have this protocol.
Can be providing with until four pressure sockets. So, in a single calibrator, can have different ranges of
pressure, for example: vacuum, 0 to 100 psi, 0 to 1000 psi and 0 to 3000 psi, or any other combination of the ranges
available. It can also be purchased with a certain number of sensors capsules and later be added others sensors.
For adding pressure sensors beyond of available in the calibrator, there is a possibility of acquisition of external
pressure module (MPYA) that communicates with the PCA-570 via USB port.
Other optional is the high accuracy sensor that, from its numerous functions, can function as default
thermometer. So, at the same time as indicates the reference temperature, possibility the calibration of any other
temperature sensor.
