5. Installation guide
5.1 Pre-installation checks and precautions
1) Beware of disconnection of the lead wire during storage and transport.
2) Check for disconnection using a tester prior to installation of the product.
3) Use a Megger (Megohmmeter) to measure and confirm that insulation resistance is within normal
range prior to installation of the product.
4) When transporting the sensor assembly to the tank and attaching to the nozzle, avoid applying
external physical force (compression, impact, etc.) on the sheathed cable (MI cable).
5) Check that the protection cover and thermocouple are free of scratches, cut marks, oil or other
contaminants.
(Even tiny amounts of foreign matter can decrease the accuracy of measurements.)
5.2 Installation requirement
1) Do not pull on or push the sheathed cable (MI cable) when installing or disassembling the product.
2) For products attached to comp’ fittings, do not loosen screws during operation. Attach the comp’
fittings to the temperature sensor prior to installation.
3) For products attached to comp’ fittings, be careful not to pull or turn the sheathed cable (MI cable)
when attaching or detaching components with the product in an assembled state. (Can be the cause
of leaks)
4) When installing a temperature sensor in an existing thermowell, inspect the inside of the thermowell
for obstructions before inserting the temperature sensor to prevent damage to the temperature
sensor or sparks due to friction during installation.
5) When installing in direct contact with the process, check that the external loads applied to not cause
deformation of the instrumentation and welded parts.
