General Information
2.2 General Sensor Information
Optional equipment, such as mounting hardware for the probe, is supplied with
instructions for all user installation tasks. Several mounting options are available, allowing
the probe to be adapted for use in many different applications.
2.2.1 Sensor Body Styles
Combination pH and ORP sensors are available in three body styles:
• Convertible Body Style ( Figure 1 and Figure 2 )— has ¾-in. NPT threads at both
ends of the body for mounting in any of the following configurations:
• into a standard ¾-in. NPT pipe tee
• onto the end of a pipe for immersion into a vessel
• Insertion Body Style ( Figure 3 )— for mounting into the pipe adapter of a ball valve
hardware assembly. This hardware enables the sensor to be inserted into or retracted
from the process without stopping the process flow.
• Sanitary Body Style ( Figure 4 )— features a built-in 2-in. flange for mounting into a
2-in. sanitary tee. Included with the sanitary-style sensor is a special cap and EDPM
compound gasket for use with the sanitary hardware.
