Signet 2650 DryLoc® Amperometric Electronics

Features

• Passes the data stored
in sensor to the Chlorine
transmitter

Description

The Signet 2650 Amperometric
Electronics provide the polarization
voltage and signal conditioning required
by all Signet Amperometric Sensors.
The 2760 Amperometric Electronics
also relays important sensor
information that is stored on a memory
chip inside the sensor and displayed on
the 3-8630-3P transmitter. Information
includes factory calibration data,
service life, calibration information and
more.

Signet’s patented DryLoc® connector
provides a quick and secure connection
to the sensor. Gold-plated contacts and
an O-ring seal ensure a waterproof and
reliable interconnect to the sensor.

Sensor maintenance, replacement and
troubleshooting has never been easier.
The DryLoc electronics can be separated
from the sensor, which allows the user
to detect a faulty sensor, electronics or
cable assembly.
