PTE1000M series pressure transmitters feature an open flush diaphragm made of AISI 316L stainless steel. They are designed to convert the gauge pressure of thick, viscous, dirty media, slurries containing suspensions of dispersed particles, adhesive and colloidal solutions. The design of sensing element does not have deep cavities and channels. This allows the sensor to be easily cleaned of adhering residues by rinsing it in cleaning fluids.
Applications: sugar, brewing, oil refineries; sewage treatment stations, waste disposal systems, mining and processing of minerals, boiler stations, public utilities, food production, pulp and paper mills.
