The PTH Diaphragm Seal construction is designed to make the differential or gauge pressure transmitter suitable for a direct manifold fit, meeting the requirements of the IEC 61518. The PTH is standard suitable for pressure measurement up to a maximum process temperature of 200°C.
This can however be increased to higher temperatures when combined with different fill fluids. The wetted parts are all made from AISI 316(L), this can be varied depending on the process conditions.
