Pressure Rating RHM 12

The maximum pressure (pmax) of a sensor is determined by its weakest part. The weakest part can be the measuring 

loops (pmax indicated below) or the construction type (pmax indicated in the Basic Order Code section, last page) or 

the selected flanges / fittings (for pmax please see respective standard).
