Pressure/temperature limits
The EL2270 and EL2271 temperature probes can be used in applications where the process temperature is within the following limits.
Where greater temperatures and pressures are present, the temperature probe should be fitted with a pocket.
For air and steam applications, flow velocities must be below 45 m/s (32 m/s for fabricated pockets).
For liquids a recommended velocity is 5 m/s (700 mm and 200 mm non-flow applications only).
