Mechanical Pressure Gauges | Higher Corrosion Resistance – Tecsis P2704 / P2714


  • Output signals: 4 … 20mA, 0 … 20mA, 0 … 10 V
  • Optional: 4 … 20 mA acc. to NAMUR NE 43
  • Flushing and vent connection for the measuring chamber
  • Solid front design
  • High overload protection
  • Accuracy class 1.6 (acc. to EN 837-3)
  • Corrosion resistant to aggressive media and environment
  • Connection position bottom, radial

The process medium chambers (+) and (-) of all stainless steel differential pressure gauges are separated by a diaphragm (see functional diagram). The difference in pressure betwen the (+) and (-) -medium chambers deflects the diaphragm. This deflection (measured travel) is transmitted to the pointer via a push rod causing a pointer deflection in proportion to the difference in pressure. Metal bellows seal the two pressure chambers off from the gauge case.

Metal supporting elements gurantee overload protection. The two downward outgoing process connections (G1/4 i) are made of corrosion resistant solid materials. The pressure connection position may be varied according to the installation conditions. The measuring element is tamper proof. The gauges can be used with gaseous, liquid and also chemically aggressive media as well as in aggressive environments. In case of highly viscous or crystallizing media. Please consult us for recommendation.

If an output signal is expected by the measuring point, the multi-functional instrument“ P2704 ND 100 rather P2714 ND 160 can be used. It connects the pressure measurement without auxiliary energy with the possibility of a sensor signal for the remote transmission of the upcoming pressure values. This instrument is particularly suitable for pressure control rather regulation.
