PT685 Flange Pressure Transmitter

  • Measuring range: Max: 0 – 40bar,  Min: 0~400mbar
  • Output signal: 4-20mA, 4~20mA/HART
  • Reference accuracy: ±0.05%, ±0.075%, ±0.1%URL
  • Range Ratio up to 20:1
  • Monocrystalline silicon technology pressure sensors
  • Double diaphragm overload protection structure
  • Integrated circuits and surface encapsulation technology of the signal transmission module
  • Three-key parameterization with isolated magnetic induction outside the housing
  • Transient voltage protection terminals

The pressure transmitter 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.
