GF Signet 2751 [3-2751-3] pH / ORP Smart Sensor Electronics

General The GF Signet 2751 pH/ORP smart sensor electronics feature field free calibration, out of range glass impedance, and broken glass detection to alert the operator to probe failure or maintenance needs. It self-configures for pH or ORP operation via automatic recognition of the electrode type. The optional EasyCal feature allows simple push-button calibration and includes an LED indicator for visual feedback.

The 2751 has a preamplified signal and features two different outputs: a two-wire 4 to 20mA loop output with EasyCal function or a digital (S3L) output which allows for longer cable lengths and is compatible with the Signet 8900 or 9900 instruments, and Profibus Concentrator.

The DryLoc electrode connector quickly forms a robust assembly for submersible and in-line installations. NEMA 4X junction enclosures are integral parts of the 2751 in-line version and are also available as accessories for the submersible.The 2751 submersible preamplifier can also be used as an in-line preamplifier when used with the 3/4 or 1 inch threaded sensors including  the 2724, 2734, 2774 and 2764 series electrodes. The in-line preamplifier can be used with Signet fittings up to DN100 (4in) and wet-tap assemblies.
