Installing the high-temperature version (with PFA lining)
The high-temperature version has a housing support for the thermal separation of
sensor and transmitter. The high-temperature version is always used for applications
in which high ambient temperatures are encountered in conjunction with high fluid
temperatures. The high-temperature version is obligatory if the fluid temperature
exceeds 302 °F (150 °C).

Insulation
Pipes generally have to be insulated if they carry very hot fluids, in order to avoid energy
losses and to prevent accidental contact with pipes at temperatures that could cause
injury. Guidelines regulating the insulation of pipes have to be taken into account.
"
Caution:
Risk of measuring electronics overheating. The housing support dissipates heat and its
entire surface area must remain uncovered. Make sure that the sensor insulation does
not extend past the top of the two sensor shells (Fig. 19).
