York CPH 6300 Handheld Pressure Indicator

Overview

The York CPH 6300 Handheld Pressure Indicator is a precision-engineered portable measurement instrument designed for field verification, commissioning, maintenance, and troubleshooting of pressure instrumentation in industrial process environments. Built upon a modular architecture, it functions as a universal digital readout unit that automatically detects and configures the full-scale range and output characteristics of any compatible York interchangeable pressure sensor module—eliminating manual scaling and minimizing setup errors. Its core operating principle relies on high-stability analog-to-digital conversion of millivolt, voltage, or current signals from calibrated piezoresistive or thin-film sensor elements, delivering traceable, repeatable readings across diverse pressure types: gauge (including vacuum), absolute, and differential. The device meets the functional safety and environmental robustness requirements typical of on-site use in demanding sectors such as petrochemical refining, chemical processing, power generation, and pharmaceutical manufacturing.

Key Features

• Modular plug-and-play sensor interface enabling rapid field replacement and range adaptation without recalibration or configuration tools
• Rugged IP65-rated housing with reinforced polycarbonate casing and rubberized impact-absorbing bumper for drop resistance and ingress protection
• High-contrast backlit LCD display with dual-unit capability (e.g., bar, psi, MPa, kPa, inH₂O) and real-time zero tracking for stable ambient compensation
• Integrated data logging with timestamped records stored internally (up to 10,000 points) and exportable via USB to GSoft software
• Built-in 24 V DC loop power supply for active sensor excitation and simultaneous mA measurement—supporting HART-compatible diagnostics
• Auto-ranging detection logic ensures correct span interpretation regardless of sensor orientation or signal polarity
• Optional high-accuracy variant certified to ±0.1 % full scale with individual NIST-traceable calibration certificate (ISO/IEC 17025 accredited)

Sample Compatibility & Compliance

The CPH 6300 is fully compatible with York’s standardized CT-series pressure sensor modules—including CT12.01 (pneumatic hand pump assembly for calibration checks), CT20.x series (stainless steel diaphragm sensors), and CT30.x (high-temperature variants). It supports both analog (mV/V/mA) and digital (RS485 Modbus RTU) sensor interfaces per EN 61000-6-2/-3 for electromagnetic compatibility. The instrument complies with IEC 61000-4-2 (ESD immunity), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) standards. Its design facilitates adherence to QA/QC protocols under ISO 9001, ISO/IEC 17025, and industry-specific validation frameworks including ASTM E74 (force and pressure calibration systems) and USP (analytical instrument qualification).

Software & Data Management

GSoft—the proprietary configuration, logging, and reporting software supplied with every CPH 6300—enables comprehensive metrological traceability. Users can perform sensor linearization, generate calibration reports compliant with ISO/IEC 17025 Annex A.2, and apply correction factors based on historical drift analysis. The software supports electronic signature functionality and audit trail generation in accordance with FDA 21 CFR Part 11 requirements when deployed in regulated environments. All logged datasets include metadata such as operator ID, location tag, environmental temperature, and sensor serial number—ensuring full data integrity and ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

• On-the-spot verification of pressure transmitters, switches, and gauges during plant turnaround or routine preventive maintenance
• Field calibration of safety-critical instruments in hazardous area zones (ATEX/IECEx-certified sensor variants available)
• Leak testing and system integrity validation in compressed air, steam, and hydraulic circuits
• Performance evaluation of control valves and pressure regulators under dynamic load conditions
• Commissioning support for new installations requiring documented as-found/as-left test records
• Training and competency assessment for instrumentation technicians in process industries

FAQ

Can the CPH 6300 be used for certifying pressure instruments in GLP/GMP environments?
Yes—when configured with the ±0.1 % accuracy option and paired with GSoft’s Part 11-compliant workflow, it satisfies documentation and audit requirements for regulated laboratory and production settings.
Is the internal battery replaceable in the field?
The rechargeable Li-ion battery is user-serviceable using standard Torx tools; runtime exceeds 20 hours per charge under typical usage.
Does the device support custom pressure units or engineering units?
Yes—GSoft allows definition of user-specified scaling equations and unit labels, enabling direct readout in application-specific terms (e.g., “% valve opening” or “cm H₂O flow equivalent”).
What is the maximum sampling rate for continuous logging?
Up to 10 Hz with external power; 2 Hz on battery power—sufficient for transient pressure event capture in most process scenarios.
Are firmware updates available, and how are they applied?
Firmware upgrades are distributed quarterly via York’s secure customer portal and installed through USB-connected GSoft—each release includes version-controlled change logs and regression-tested validation protocols.
