Gefran TPFADA – Pressure Transmitter with Flush Diaphragm

The TPFADA is a pressure transmitter featuring a flush diaphragm made from 17-4PH stainless steel and utilizes bonded strain gauge technology on a steel body. It is designed for use with high-viscosity or deposit-forming fluids where conventional transmitters with internal measuring chambers may clog or exhibit response delays. Typical compatible media include oils, viscous fluids, rubber compounds, slurries, and chemicals compatible with 17-4PH stainless steel.

FAQ

When to select TPFADA over TPF?
When a powered output (4…20 mA or Vdc) is required instead of mV/V.

When to select TPFAS?
When a smaller flush diaphragm or alternative connection geometry is needed.

Overview

TPFADA Series flush diaphragm pressure transmitters are based on bonded strain gauge on stainless steel technology.

Thanks to the strong flush diaphragm made with 17-4 PH stainless steel, TPFADA is particularly suitable for pressure measurement where the media is with high viscosity (thick fluids, oils, rubber, pulps, chemical products, etc.) and the traditional transducers with internal measuring chamber cannot be used.

The high thickness of the diapragm makes the product very reliable and suitable for heavy industrial application. Internal state of the art electronics allows a wide range of current and voltage signal outputs, as well as the innovative “Digital Autozero & Span” function is able to perform an easy and quick automatic zero adjustment after the installation, simply with the touch of a magnetic pen, supplied as standard.
