Description
FOXBORO H90JFBD022J0 — Pressure Transmitter
Product: H90JFBD022J0, Electronic Pressure Transmitter
Manufacturer: Foxboro (a Schneider Electric brand, part of the Foxboro Evo™ platform)
Primary Application: An industrial-grade pressure transmitter designed for accurate and reliable measurement of gauge pressure in demanding process applications across industries such as oil & gas, chemical, power, and water treatment.
1. Core Overview & Product Line
The Foxboro H90JFBD022J0 is a specific model within the Foxboro H90 Series of electronic pressure transmitters. The H90 series is renowned for its robust construction, high accuracy, and digital communication capabilities, forming a core part of the Foxboro Evo™ instrumentation portfolio.
Key Concept: It is a «smart» transmitter, combining a precision sensor with micro-processor-based electronics. It outputs a standard 4-20 mA analog signal proportional to the measured pressure, while simultaneously supporting digital communication via the HART protocol for configuration and diagnostics.
2. Key Features & Functions
-
High-Performance Sensor: Utilizes a proven capacitive sensing cell for excellent stability, repeatability, and resistance to shock/vibration.
-
Smart Communication: HART® protocol (Highway Addressable Remote Transducer) allows for remote configuration, calibration, and diagnostics using a hand-held communicator or asset management software (e.g., Foxboro/Emerson AMS) without interrupting the 4-20 mA signal.
-
Robust Construction: Housing rated for harsh environments (typically NEMA 4X / IP66). The
Fmaterial (316L SS) offers good general corrosion resistance. -
Local Operator Interface (LOI): Equipped with a non-intrusive magnetic adjustment mechanism or a local display (depending on specific option) for configuration and troubleshooting without opening the electronics compartment.
-
Advanced Diagnostics: Provides internal diagnostics for sensor health, process condition alerts, and configuration changes.
3. Common Technical Specifications
-
Output: 4-20 mA DC, two-wire, with HART 5/7/8 protocol.
-
Power Supply: 12-45 V DC (Loop-powered).
-
Accuracy: Typically ±0.1% of calibrated span (for the
022sensor). -
Turndown Ratio: Up to 100:1, allowing significant range adjustment in the field.
-
Process Connection: Standard is likely 1/2″ NPT female or G1/2″.
-
Electrical Connection: Conduit entry (1/2″ NPT) or integral junction box (as per
J). -
Display: Optional local LCD display (not standard on all
Jvariants; requires a specific option code). -
Ambient Temperature: -40°C to +85°C (-40°F to +185°F).
4. System Integration & Configuration
-
Installation: Mounts directly to a process connection via its threaded port. The electrical conduit connects to the terminal block inside the housing.
-
Wiring: Simple two-wire connection in series with the loop power supply and the control system input (DCS, PLC).
-
Configuration: Parameters like Lower Range Value (LRV), Upper Range Value (URV), damping, engineering units, and device tags are set using:
-
A HART communicator (e.g., Emerson 475).
-
Asset Management Software (e.g., Foxboro/Emerson AMS).
-
The magnetic tool and local buttons (if equipped with a display).
-
-
Commissioning: Requires zero and span calibration, which can be performed remotely via HART or locally.
5. Typical Applications
Used anywhere precise gauge pressure measurement is required:
-
Pump Discharge Pressure: Monitoring and control.
-
Tank Level (Hydrostatic): When used with the level calculated from pressure.
-
Filter Differential Pressure (with two transmitters).
-
Pipeline Pressure: Monitoring in oil & gas transport.
-
Steam Header Pressure: In power plants.
