How do I handle high temperature media?

Pressure transducers are being used by many engineering firms and contractors for steam applications.  

Setra may specify a compensated range of -4º to 176ºF, but the temperature of the steam can be much higher.  

With the use temperature standoffs, the steam temperature will be greatly reduced by the time it reaches the transducer. Here is the link to Setra’s Application Note for the selection of standoff materials and lengths:

Ideally the steam line tap should be on the bottom of the steam line since heat rises and steam will not replenish the line. Some example of pigtails (also referred to as syphons) are below. 

Steam will exit the pipe and fill the line to the transducer. Due to the length of tubing in an atmosphere of 100ºF, the steam will condense and create a water trap. The water trap creates isolation of the steam temp and the air pressurizing the transducer.
