Measurement Tube Pressure Ratings The maximum pressure (Pmax) of a sensor is determined by its lowest rated part. The lowest rated part can be either the measurement tube (Pmax indicated below), the construction type (Pmax indicated in the Part Number Code section) or the process connection (for Pmax see published standards or manufacturer information). Pressure Code Material Code *Only with N1, NA, E2 temperature range (note Super Duplex min. temp. is -40°C) and seal-less construction type Other Materials and Pressure Ratings Higher pressure rated measurement tubes in the materials above...
