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 max. operating temp. is 130°C) and PF0 construction type (max. ANSI 300/PN40) **Only with N1, NA, E2 temperature range (note min. temp. is -40°C) and seal-less...
