Differential Pressure Transmitters Dealers in Bikaner

• Fischer: DE28

Working Principle: -DE28 works on principle of movement of pressure diaphragm due to pressure or differential pressure applied on either side. Fischer DE28 has NBR or Viton diaphragm, thus offering continuous, repetitive high performance. The applied pressure create unbalanced force on the springs, which keep moving until new equilibrium reached. The centre mounted tappet transfers the motion of diaphragm system to core of inductive displacement transducer. Therefore, subsequent converter circuit converts this displacement into electrical output signals. Key Features: 1.Robust design with high repeatability of switching contacts 2.Over pressure protection 3.Short circuit protection 4.Maintenance free due to inductive circuit movement Key Specifications: 1.Measurement range: 0-400 mbar to 0-6 bar 2.Operating temperature: Ambient: 0°C to +70°C 3.Protection class: IP54 per DIN EN 60529 4.Static operating pressure: 16 bar 5.Diaphragm: NBR or Viton 6.Measuring linearity: < 2.0% Full scale 7.Measuring hysteresis: < 1% Full scale 8.Operating voltage: 24 V DCAC 9.Output signal: (0) 4-20 mA or 0-10 V, linear, proportional 10.Zero adjustment with the dial 11. 1 or 2 adjustable microswitches 12.Pressure chamber: Brass 13.
