Gefran TPF – Pressure Sensor with Flush Diaphragm

The Gefran TPF is a pressure sensor equipped with a flush 17-4PH diaphragm and a non-amplified mV/V output. It utilizes bonded strain gauge technology on stainless steel, designed for high-viscosity fluids or media with deposits, where conventional transmitters with internal measuring chambers may clog or exhibit delayed response.

Technical Data

  • Measuring ranges: 0…10 to 0…1000 bar
  • Accuracy: H ±0.2% FS typical, M ±0.5% FS typical
  • Overpressure: 3x FS, max 2000 bar
  • Burst pressure: 4x FS, max 2000 bar
  • Response time: < 1 ms
  • Process temperature: -40…+120 °C
  • Temperature compensation: -20…+85 °C
  • Protection: IP65 / IP66 / IP67, depending on connector
  • Wetted parts: 17-4PH stainless steel

Media and Applications

Suitable for viscous oils, pastes, rubber, slurries, resins, chemicals, and dosing pumps. The flush diaphragm minimizes dead volume and material accumulation points. Not classified as a sanitary device without process connection, cleaning, and material compatibility verification.

Electrical Output and Selection

The mV/V output requires a strain gauge bridge input or external signal conditioner. For direct PLC connection with 4…20 mA or 0…10 V, use the TPFADA version. For a smaller diaphragm and amplified outputs, consider TPFAS.

Connections and Sealing

Standard process connections: M18x1.5 and G 1/2” male; 3/4-16 UNF on request. Installation must avoid mechanical loading on the diaphragm and ensure full media contact without material entrapment.

Installation

Grounding via machine body is required. Use shielded cable and separate power and signal wiring. Shield connects at the connector side only, left open at the PLC side per installation guidelines.

Standards / Declarations

Product page provides EU and UK Conformity Declarations for the TPF series. No actuator options; this is a measurement sensor, not a control element.

Overview

TPF Series flush diaphragm pressure transducers are based on bonded strain gauge on stainless steel technology.

Thanks to the strong flush diaphragm made with 17-4 PH stainless steel, TPF 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 and very high precision mechanical machining make TPF product the ideal solution for above needs, where the non amplified mV/V sensor has to be used.
