Keller produces many complementary accessories that enhance
the usability of our pressure transmitters, including portable
pressure calibrators, complete with digital pressure indicators and hand-operated
low and high pressure pumps. Available in ranges from vacuum to
700 bar, these calibrators are completely self-contained and can provide
power to the transmitter being calibrated, making possible field calibrations
in remote locations where power is not available. Specific versions also
include a datalogging function, enabling the technician to retain a record
of actual data that can be subsequently downloaded and made a part of the
permanent calibration record.
