Description
+GF+ 3-2751-2 - Chlorine-Sense/Pt1000-Temp-Calibrate - PVC 3/4"NPT Low Range Free Chlorine Water Monitoring Electrode
In-Line DryLoc® pH/ORP Smart Sensor Electronics (NEMA 4X, Dual Output)

The 3‑2751‑2 is the in‑line (PBT+PP) variant of Signet's 2751 DryLoc® pH/ORP smart sensor electronics, processing analog electrode signals into isolated 4-20 mA (12-24 VDC) or digital S³L (5-6.5 VDC, 9600 bps) for direct PLC or 9900/9950/0486 tie‑in.

Key features include: NEMA 4X/IP65 rating, compatibility with all DryLoc pH/ORP electrodes (2724-2726, 2734-2736, 2744-2747, 2756-2757), pH range of -1…15 / ORP ±2000 mV, operating temperature of 0…85 °C, and cable length up to ≤ 305 m.

Automation Role & Applications

Enables probe‑health monitoring, broken‑glass/high‑impedance detection, memory‑chip calibration transfer, and optional EasyCal functionality—auto‑configures pH vs ORP, ATC via electrode Pt1000.

Typical applications include: wastewater neutralization, scrubber systems, effluent monitoring, surface finishing, pool/spa water treatment, and aquatic life‑support systems.

The DryLoc® quick‑connect system allows hot‑swapping electrodes without rewiring, maintaining 24/7 process loops audit‑ready.
