The SPC4000 pressure calibrator can perform automated multipoint
calibrations and offset corrections on demand to DSA & ZOC
pressure scanners. Inorder to do this the calibrator must be used
with the Scanivalve SPCPLU. The reference side of the gauge
transducers can be connected to an alternate remote location
(tunnel static, elevated line pressure, static basket, etc). The
calibrator can also send known pressures to all of the DSA/ZOC
sensors to insure they are reading correctly (System
Validation). The calibration system can be used for many
applications including multi-point calibration of DSA and ZOC
pressure scanners, zero offset correction, and leak testing.
The calibrator can also be used in the local/manual mode utilizing
the front panel touch screen or remotely via Ethernet. It
would be used in this standalone mode to regulate and measure
pressures to calibrate individual pressure transducers.
The model SPC4000 pressure calibrator is designed to provide
automated calibration of Scanivalve Corp's DSA and ZOC pressure
scanners. The calibration system consists of 3 components.
1. The heart of the calibration system is the
Scanivalve pressure calibrator, model SPC4000. The SPC4000
calibrator has up to two independent precision pressure regulators.
Each regulator can have up to two gauge transducers; thus up to 4
transducers per calibrator.
2. Scanivalve's Pneumatic Logic Unit (SPCPLU) is
required for automated DSA & ZOC calibrations. This unit
contains the pneumatic solenoid valves and manifolds required to
perform single or multi-range calibrations, as well as zero offset
corrections.
3. A utility program, PressCal is included with the
SPC4000. It performs automated or manual calibrations on all DSA
and ZOC pressure scanners by controlling the pressure calibrator
and SPCPLU. PressCal updates the module calibration
coefficient files and generates "as received" and calibration
validation reports.
