ABB PPD113B01-10-150000 | Precision Differential Pressure Sensor | Critical Obsolescence Advisory for Legacy Process Instrumentation

  • Model: PPD113B01-10-150000
  • Manufacturer: ABB (formerly part of the ABB Kent-Taylor / K-TEK product line)
  • Product Family: PPD100 Series – High-Accuracy Differential Pressure Transmitter
  • Core Function: Measures differential pressure for flow, level, or filter monitoring; outputs standardized 4–20 mA signal
  • Lifecycle Status: Obsolete – No longer manufactured or supported by ABB; superseded by the ABB 2600T/266DSV and Turbine Meter + DPT integration platforms
  • Procurement Risk: High – Very limited verified inventory; secondary market units often lack calibration certificates or have unknown service history
  • Critical Role: Provides primary measurement input for custody transfer, boiler drum level, or safety-critical flow loops; failure can lead to process upset, safety system misoperation, or regulatory non-compliance
Category: SKU: PPD113B01-10-150000 ABB

System Role and Operational Impact

The PPD113B01 series was widely deployed in:

  • Boiler drum level measurement (using three-element feedwater control)
  • Orifice plate flow metering in custody or critical process streams
  • Filter or strainer differential pressure monitoring
  • HVAC and water treatment plants

Failure modes include:

  • Zero drift due to diaphragm fatigue or temperature hysteresis → inaccurate flow/level readings
  • Moisture ingress in terminal housing → intermittent signal or short circuits
  • Lightning/surge damage on 4–20 mA loop → complete output failure

Because many installations use these transmitters in safety-related or regulatory-compliant loops, an uncalibrated or failed unit can:

  • Trigger false trips in boiler protection systems
  • Cause fiscal metering errors (leading to financial loss or audit penalties)
  • Violate environmental reporting requirements (e.g., stack flow monitoring)

 

Reliability & Common Failure Modes

  • Capacitive sensor drift: Long-term exposure to overpressure or thermal cycling degrades baseline capacitance, causing offset errors.
  • Seal degradation: O-rings or fill fluid in impulse lines dry out or leak, especially in high-temp services (>100°C).
  • Electronics aging: Analog signal conditioning boards suffer from resistor/capacitor drift; no digital recalibration possible without HART.
  • Corrosion: In coastal or chemical environments, terminal blocks and housing corrode, increasing loop resistance.

Lifecycle Status & Migration Strategy

ABB discontinued the PPD100 series in the late 2000s, consolidating pressure instrumentation under the 2600T family (now part of the ABB Measurement & Analytics portfolio).

Direct Modern Equivalent:

  • ABB 266DSV – Smart differential pressure transmitter with:
    • ±0.04% accuracy
    • HART 7 / FOUNDATION Fieldbus / PROFIBUS PA
    • Built-in diagnostics (sensor health, loop integrity)
    • SIL 2/3 certification per IEC 61508
    • Backward-compatible mounting (with adapter kits)

Migration Considerations:

  1. Mechanical: Verify process connections—adapter flanges may be needed.
  2. Electrical: Existing 4–20 mA wiring can usually be reused.
  3. Calibration: New transmitter requires re-calibration to match original span (1500 mbar).
  4. System Integration: If used in a DCS/SIS, update I/O configuration and re-validate loop performance.

Interim Risk Mitigation:

  • Perform annual calibration with traceable standards
  • Maintain at least one spare with valid calibration certificate
  • Install surge protectors on 4–20 mA loops in exposed areas
  • Document as-found/as-left data for compliance audits
