+GF+ 3-2751-3 10m - pH-Detect/Signal-Output - Chem Resist Submersible Smart Sensor
The +GF+ Signet 3‑2751‑3 is a DryLoc® pH/ORP smart sensor electronics module supplied as the submersible (immersion) assembly, typically specified with a ~10 m 3‑conductor shielded cable for long cable runs from tanks/sumps back to a transmitter location. It acts as a close‑coupled pre‑amp/conditioner for a memory‑chip‑enabled pH or ORP electrode, converting the electrode signal into a fixed, isolated 4–20 mA loop ora digital S³L (Serial Sensor Link) feed to a Signet 9900/9950 controller or 0486 Profibus concentrator. Key attributes include NEMA 6P/IP68 immersion capability, built‑in broken‑glass & high‑impedance diagnostics, and support for remote/field‑free calibration via stored electrode data.
Its main automation function is continuous, low‑noise liquid chemistry measurement with diagnostics and minimal recalibration downtime—ideal for water/wastewater treatment, neutralization/scrubber control, effluent monitoring, surface finishing, and pool/aquatic life‑support loops. Advantages come from the DryLoc gold‑plated quick‑connect (no wet wiring), probe health visibility (glass integrity/impedance trending), and long‑run signal integrity (4–20 mA or digital S³L) that lets you locate the controller away from the wet point without sacrificing stability.
