Pressure transmitter for food / bio / pharmaceutical industries (data sheet 9712)
Field housing stainless steel
The pressure transmitter PTFi is suitable for precisely measuring and monitoring vacuum, absolute pressures and positive pressures of liquid as well as gaseous media for pressure ranges from 0 – 400 mbar to 0 – 40 bar.
Available as process connections are hygienic connections such as clamp (standard), dairy pipe or thread connections (optional) with a flush-welded stainless steel membrane, which can be combined with a cooling extension for medium temperatures up to +300 °C, if necessary.
The robust stainless steel field housing has a high degree of protection IP67 as well as all properties for residue-free and antibacterial cleaning.
The pressure transmitter supports communication via HART® protocol. A turn-down span to 1:10 is available. A version with safety functions according to SIL2 is optionally available.
