PPC2+ BG0002 Operation and Maintenance Manual

BBO

This manual is designed to be used in conjunction with the PPC2+ Operation and Maintenance Manual (Document Number 550091). It contains information specific to the BG0002 model of PPC2+ Pressure Controller/Calibrator.

PPC2+ BG0002 is identical in conception and most features to other PPC2+ models. PPC2+ BG0002 is a specialized PPC2+ model designed to optimize very low gauge pressure performance. This manual covers the aspects of PPC2+ BG0002 that differ from other PPC2+ models.

To operate a PPC2+ BG0002, use the PPC2+ Operation and Maintenance Manual (Document Number 550091) and follow the instructions and information. Refer to this manual for details on BG0002 specifications, installation and set up, pneumatic schematic differences, and [SPECIAL], <5Valves> operation. PPC2+ BG0002 is normally used in conjunction with accessory package PK-PPC-BG-DVU (P/N 401699). This package is delivered with its own instruction sheet.

PPC2+ BG0002 Operation and Maintenance Manual

1. INTRODUCTION

1.1 PRODUCT OVERVIEW

PPC2+ BG0002 is a special model of the PPC2+ line of pressure controller/calibrators. PPC2+ BG0002 is identical to other PPC2+ models except for:

1) Use of a special low pressure “bi-directional gauge” reference pressure transducer (RPT).

2) This model has only one RPT. It does not support dual RPTs.

3) Inclusion and control of two additional internal control valves (a TEST(+)/TEST(-) bypass and a TEST(-) vent) with local and remote control capabilities for both.

4) Special recalibration recommendations for the very low pressure, bi-directional gauge RPT.

PPC2+ BG0002 is normally used in combination with accessory package PK-PPC-BG-DVU (P/N 401699) which includes two thermally isolated volumes installed in the test line to improve control stability. This package is delivered with its own instruction sheet.

Once a PPC2+ BG0002 has been put into service, its operation is identical to other PPC2+ models.

This manual is intended to be used as a supplement to the PPC2+ Operation and Maintenance Manual

(Document Number 550091). To operate a PPC2+ BG0002, use the PPC2+ Operation and Maintenance Manual and refer to this manual for aspects specific to the BG0002 model. These are primarily the operating specifications, installation and use recommendations, recalibration recommendations.

Pressure Limits: Line Pressure (min/max low side): 80 to 110 kPaa (11.6 to 16 psia)

Maximum/Minimum Working Test Pressure: +15/-15 kPa (+2.2/-2.2 psi)

Maximum/Minimum Test Pressure without Damage: +16.5/-16.5 kPa (+2.4/-2.4 psi)

Required Supply Pressure: SUPPLY port: 70 kPa gauge (10 psi)

EXHAUST port: Vacuum of 70 kPaa (10 psia) or less with displacement of at least 90 lm (3 cfm)

1.2.2 PRESSURE MEASUREMENT SPECIFICATIONS

All values are ± span of the active range unless otherwise indicated.

Warm Up Time: 30 minutes recommended for RPT temperature stabilization

Resolution: To 1 ppm, user settable by individual range

Temperature Effect: Fully compensated with active independent temperature measurement

from 10 to 40 °C

± 0.005 % maximum temperature effect in normal ambient 15 to 35 °C operating range

Acceleration Affect: ± 0.02 %/g maximum, worst axis

Allows operation at ± 20° from reference plane without significant effect

Precision

Stability (w/ Autozero): 90 day

Measurement Uncertainty

1 Measurement Precision: Combined linearity, hysteresis, repeatability of measurements made by

the reference pressure transducer.

2 Measurement Uncertainty: Maximum deviation of the reference pressure transducer indication from

the true value of measured pressure including precision, stability, temperature effect and calibration standard accuracy of ± 0.003 % of reading.

1.2.3 PRESSURE CONTROL SPECIFICATIONS

All values are ± span of the active range unless otherwise indicated. Control specifications

assume that a PK-PPC-BG-DVU dual volume unit is installed on the TEST lines and that a vacuum is applied to the PPC2+ BG0002 EXHAUST port.

Modes and Ready

Parameters:

Static: Sets pressure within hold limit and stops active control until hold

limit is exceeded

Pressure is Ready when within hold limit and stability test is met

Dynamic: Sets pressure within hold limit and continuously adjusts as close as

possible to target

Pressure is Ready when within hold limit
