Flush Diaphragm Pressure Transmitter

Introduction

Pressure and vacuum measurements, absolute or gauge Ceramic, TRANSBAR® sensing element Zero adjustment (± 10 % of range) Welded construction - reinforced product Modularity of electrical and hydraulic connections Stainless steel flush diaphragm Highly resistant to severe process conditions Marine version (Bureau Veritas Marine) LCIE 02 ATEX 6133X

An all stainless steel construction with flush diaphragm connection makes these transmitters ideally suited for measurements on viscous and heavy fluids suchs as paint, pulp and paper, and most uses in the refrigeration field. Hydraulic connections : G 1/2, G 3/4, G 1, 1/2 NPT
