2.3.2 Quik-Loc Mounting for Rosemount 397
The Quik- Loc mounting is used with the Rosemount 397 sensor only.
WARNING
Once the Quik-Loc unit is installed the operator should wait for the process to cool to a safe temperature,
use the pressure drain valve to relieve all process pressure and observe the pressure on the pressure
gauge for proper removal of the sensor without spray or bodily injury. The Quik-Loc kit used with the
Rosemount 397 sensor is not recommended for use with hazardous, corrosive, or strong oxidizing chemi
cals due to a risk of spray or bodily injury.
WARNING
It is recommended that a thermometer, drain valve to relieve pressure and pressure gauge be inserted
near the Quik-Loc assembly (see Figure 2-5).
Wrap the pipe threads of the Twin-Kam Kamloc coupler with Teflon tape before placing it into the
process pipe. The coupler can be connected to any 1 in. process connection and must be mounted
within 80° of vertical, with the electrode facing down. Once the coupler is in place, the adapter
should be positioned onto the back end of the sensor. (See Figure 2-5) Remove the parafilm wrap
ping from the two 0-rings on the sensor, grease the o-rings with the lube provided, and feed the
sensor cable through the adapter. Once the adapter is slipped over the sensor's back end, the
retaining ring (which is included with every Rosemount 397 sensor) should be installed on the black,
grooved, back end of the sensor body. The retaining ring secures the sensor into the adapter. The
adapter/sensor assembly is now ready to be inserted into the coupler. With both arms of the coupler
in the released position, insert the adapter/sensor assembly into the coupler.
Note: The adapter can not be inserted completely or properly unless both arms are in the fully
released position (see Figure 2-5).
Once the adapter has been properly placed in the coupler, both arms should be positioned in the
locked position. A Sur- Loc™ spring arm has been provided on one arm so that the arm cannot
be opened until the spring is released.
Note: The sensor may obstruct flow through smaller pipes.
Once the arms of the coupler have been locked in position, use tamper-evident safety wire on the
metal rings of the Twin-Kam arms to prevent unauthorized and/or untrained personnel from using
the Quik-Loc unit.
WARNING
It is the responsibility of each company using the Quik-Loc Kit/ 397 TUpH Sensor to train personnel of the
injury risks associated with using a quick-release coupler that is placed in a hot or pressurized process.
The Quik-Loc unit should be used only within the pressure and temperature limits stated for the
Rosemount 397 sensor in Section 1.2.
