FOXBORO 873EC-JIPFGZ – Electrodeless (Toroidal) Conductivity Transmitter for Tough Process Media

The FOXBORO 873EC-JIPFGZ is an electrodeless (toroidal) conductivity transmitter designed for demanding process applications where coatings, contamination, or wide ranges make conventional contacting probes a headache. From my experience, this family is a favorite for CIP caustics, acids, high‑conductivity brine, and wastewater streams—places where you want stable readings with minimal cleaning. You might notice the rugged field enclosure and clear display; on most installs, commissioning is straightforward once the sensor and temperature input are landed.

Key Features

• Electrodeless (toroidal) measurement – Resists coating and polarization; ideal for caustics, acids, and high‑conductivity media.
• Wide measuring range – Typically covers from low mS/cm into very high conductivity regions without frequent range changes.
• Temperature compensation – Supports integral/remote temperature input for compensated conductivity or concentration readout.
• Industrial field enclosure – Weather‑resistant housing with local display/keys for quick set‑up and on‑site checks.
• Clean integration – 4–20 mA analog output; relay/alarm contacts and HART on many variants to simplify DCS/PLC mapping.
• Sensor compatibility – Pairs with FOXBORO inductive probes (e.g., 871EC series) and equivalent toroidal sensors.

Technical Specifications

Application Fields

I typically see 873EC units where conductivity is critical and media can foul conventional electrodes:

• Food & beverage CIP systems – caustic/acid concentration control with temperature compensation.
• Chemical processing – acid/caustic dilution skids and blend ratio monitoring.
• Desalination and brine streams – high‑conductivity monitoring without electrode wear.
• Wastewater & utilities – tower blowdown, neutralization, and general plant effluents.

A maintenance supervisor mentioned last season, “We swapped to a toroidal probe with the 873EC and stopped weekly cleanings—the trend stayed steady through the batch.” That lines up with what I’ve seen on heavy CIP use cases.

Advantages & Value

• Reliability – Non‑contact design is far less sensitive to coating or polarization than contacting cells.
• Compatibility – Works seamlessly with FOXBORO toroidal sensors; easy to map into DCS/PLC via 4–20 mA and, in many cases, HART.
• Cost savings – Reduced cleaning and longer sensor life usually cut maintenance hours.
• Supportability – Clear local interface and common configuration workflow simplify changeovers.
• Delivery assurance – Stock‑based lead times help you hit outage windows without re‑engineering.

Installation & Maintenance

• Mounting & environment: Field‑mount on wall or 2″ pipe; keep ambient −20…+60 °C; avoid corrosive atmospheres on the enclosure.
• Sensor placement: Install toroidal sensor fully wetted in a straight‑run section where flow is representative; follow the orientation notes.
• Wiring & EMC: Use shielded cable for sensor/temperature leads; route away from VFD motor cables; bond shields at the instrument.
• Configuration: Enter cell factors, temp coefficients, and output scaling; verify with a standard solution or a trusted process reference.
• Routine care: Visual inspection of gaskets/cable glands, check trend stability; clean sensor occasionally if process demands it (far less frequent than contacting cells).
• Spares strategy: Keeping one matched transmitter/sensor set on the shelf is, in most cases, cheap insurance for critical loops.

Quality & Certifications

• Manufactured under FOXBORO/Schneider Electric quality systems (ISO 9001 aligned).
• CE compliance for EMC/safety on relevant variants; UL/cUL or hazardous‑area approvals may be available depending on build.
• RoHS compliance by series generation; we can verify by part/serial if needed.
• Warranty: 365 days repair/replace coverage from delivery.
