Union Mount (for Tee, Weldolet, Pipe Saddle, etc.)
The convertible style sensor may be mounted in any standard 2-inch NPT fitting (pipe tee, weldolet, pipe
saddle, etc.) by using a special Honeywell union-mount adapter.
Step
1
Install a standard 2-inch NPT fitting (pipe tee, weldolet, pipe saddle, etc.) into the process line.
Preferably, the fitting should be made of a material to provide a suitable maximum
pressure/temperature rating for the application. Refer to Subsection 2.1 for specifications.
2
Fasten the special short nipple of the Honeywell union-mount adapter into the 2-inch NPT fitting.
Carefully tighten the threaded connection to prevent leaks. Figure 3-2 and Figure 3-3 respectively
show pipe tee and flange mounting details.
3
Route the sensor cable through the cord grip of the Honeywell union-mount adapter, and tighten the
sensor into the adapter's flanged piece.
4
Wire the sensor directly to the instrument or indirectly using interconnect cable and a junction box. In
either case, make sure that the sensor or interconnect cable is cut to the proper length to minimize
electromagnetic interferences.
A
Make sure to very carefully terminate the wires and shields of the respective cable(s) by
following the procedure described in Section 4.
B
Refer to the instructions in the instrument manual to electrically connect the sensor to the
instrument.
5
Before mounting the sensor into the process line or vessel, calibrate the measurement system with
conductivity reference solution using the procedure in the instrument instruction manual.
6
After calibration, mount the sensor into the installed 2-inch NPT fitting:
A
Properly seat the gasket into its mating groove on the special short nipple of the Honeywell
union-mount adapter.
B
Carefully place the sensor into the short nipple, making sure the gasket is in place and
contacting the adapter's flanged surface.
C
Tighten the union-mount adapter lock-ring onto the special short nipple to secure the
connection.
This completes the sensor mounting using the special Honeywell union-mount adapter.
