2 UPC5200/UPC5210 Operation and Maintenance Manual
• Calibration Integrity: Tamper-proof design. Once calibrated, numerous safeguards guarantee the integrity
of pressure readings obtained. Display prompting provides the operator with functional status information
during both operation and calibration.
• Pressure Source (UPC5200 only): An external supply cylinder with a volume of 83.3 std. cu. ft. of N
2
provides up to 2,216 psig of pressure for calibration and test. This pressure source drives a pneumatically
operated 10 to 1 intensifier contained within the UPC5200. Therefore, a 1,000 PSI input is amplified to
10,000 PSI.
• Simple Operation: All controls, indicators and pressure ports are accessible from the front panel.
Accompanying operator's manual provides clear, concise instructions for system operation.
• Data Input Capability: A front panel-mounted connector and selector switch permit the 4-20 mA current
signal from the gauge-under-test or voltage to be displayed. Transducer excitation voltage of 28 VDC is
provided standard.
• Safe, Clean Operation: All pressure components are made of stainless steel and proof-tested to at least
150% of maximum operating pressure. In addition, the system contains a high-pressure burst disk to
protect both the operator and system components from harm in the event of inadvertent over-pressurization.
The heart of this calibration system is a highly stable and repeatable pressure transducer. These sensors produce
an electrical output signal which is linearly proportional to the applied pressure. By combining the sensors with
sophisticated microprocessor-based circuitry, an even higher degree of operational accuracy and precision has
been accomplished. For example, computer-generated correction curves for both the non-linearity and the
hysteresis of the sensors improve these characteristics by an order of magnitude or more. In addition, a self-check
feature ensures long-term accuracy by utilizing the computer to generate and control an internal shunt calibration
mode of operation. The indicators full-scale reading is compared against, and if necessary, corrected to the
digitally-stored value for full scale obtained at the time of initial pressure calibration.
In addition to the features, the UPC5200/UPC5210 pressure calibrator is easy to use. Two micro-metering valves
and vernier are provided to control the internally intensified nitrogen while the digital display indicates precisely
the magnitude of the applied test pressure. Also, a simple push-button switch provides zeroing of the pressure
display. The
Range selection, as well as, Pressure and Current display selections are accomplished via a pair of
clearly marked rotary switches. Over-pressure protection is provided through a fully-adjustable pressure
regulator, which is manually set for each new device being tested.
With respect to calibration, the instruments have been designed and programmed to provide the operator with
various prompting symbols and legends during each phase of the calibration sequence. Also, to prevent
unauthorized tampering or calibrations, programming or calibration can only be achieved with the aid of a
separate, plug-in calibration console (PN 60109). Also, the electronic circuitry has been designed without any
potentiometers or adjustments, eliminating the possibility of unwanted changes. Finally, the computer has been
programmed with a series of internal self-diagnostic routines which continually monitor and check every bit of
data stored and processed by this system. The computer immediately notes or shuts down operation in the event
of an out-of-tolerance reading or any outright failures.
