Describe
+GF+ Signet 2750 DryLoc® pH/ORP Sensor Electronics

The Signet 2750 pH/ORP Sensor Electronics featuring
the DryLoc® connector, provides a variety of functions to
suit various requirements.
The 2750 has a preamplified signal and features two
different outputs: a two-wire 4 to 20 mA loop output
with EasyCal function or a digital (S 3 L) output which
allows for longer cable lengths and is compatible with
the Signet 8900 or 9900 instruments, and Profibus
Concentrator.
The 2750 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 DryLoc electrode connector quickly forms a robust
assembly for submersible and in-line installations.
NEMA 4X junction enclosures are integral parts of
the 2750 in-line version and are also available as
accessories for the submersible 2750.
The 2750 submersible preamplifier can also be used as
an in-line preamplifier when used with the 3/4” or 1”
threaded sensors including the 2724, 2734, 2774 and
2764 series electrodes. The 2750 In-line preamplifier
can be used with Signet fittings up to DN100 (4 in.) and
wet-tap assemblies.
