Temperature requirements
Thermal loading from the process and ambient environment affects the temperatures of the
electronics, as well as the seals inside the level transmitter. Figure 3-28: SLG720 temperature
limitsdefines the limits of ambient and process temperatures as they pertain to specific seal
materials in the transmitter.
The SLG726 (high pressure high temperature (HTHP) process connector) must be pressure
de-rated at elevated temperatures. The pressure rating at operating temperature is specified in
Figure 3-30: SLG726 Maximum pressure based on maximum operating temperatureand in
tabular form in Table 3-16.
