2.1. Sensor Description
The ECFP21A1A1 1½ inch pH sensor uses a differential measurement technique to maximize lifetime in
continuous industrial applications. The ground rod and encapsulated preamplifier construction reduce the
effects of ground loops and allow the pH signals to be transmitted up to 3,000 feet. A replaceable heavy-
effects of ground loops and allow the pH signals to be transmitted up to 3,000 feet. A replaceable heavy-
duty quad junction salt bridge makes it simple to refurbish the sensor when necessary. The large reference
reservoir filled with buffered solution minimizes the effects of dilution and extends the life of the reference
reservoir filled with buffered solution minimizes the effects of dilution and extends the life of the reference
electrode. The wires in the sensor cable are color coded to allow for quick and easy installation into the
Alpha pH2000D Controller.
Alpha pH2000D Controller.
The sensor body has 1½ inch NPT threads for the following
mounting options:
mounting options:
¾
Standard 1½ inch NPT pipe tee insertion.
¾
Immersion mounting assembly.
Salt bridges come in two styles:
¾
Protected for standard applications.
¾
Flat for sanitary applications.
The wires in the sensor cable are color coded to match the
terminal connection within the Alpha pH2000D Controller.
