Fischer pressure transmitter Building technology DE28

Gas Alarm India offer Fischer DE28 differential pressure transmitter for liquid and gas media for overpressure, partial vacuum and differential pressure monitoring. Measuring Transmitter for overpressure, partial vacuum and differential pressure of liquid and aerial media. Ranges: 0-0.4 up to 0-6 bar. This series of transmitter is suitable for various measuring applications in the field of industrial and sanitary techniques.

Typical applications:
 
  • Measurement of differential pressure between forward and return flow in heating systems
  • Monitoring of filters, blowers and compressors

Features:
 
  • Overpressure protection
  • Maintenance-free due to inductive movement
  • Multiple applications
  • rugged design

Construction and Operation: This transmitter is based on a rugged and uncomplicated diaphragm movement. The operating principle of the system is identical for all applications of this type. In a state of equilibrium, the forces of the springs on both sides of the diaphragm are balanced. The pressure or differential pressure to be measured creates an unbalanced force of the springs for the measuring range until a new equilibrium is reached. A centre-mounted tappet transfers the motion of the diaphragm system to the core of an inductive displacement transducer. The subsequent converter circuit converts this motion into an electrical output signal 0(4) - 20 mA linear, 3-wire connection. The transmitter is reverse battery and short circuit protected.

Specifications:
 
  • Measuring ranges 0-0.4 bar to  0-6 bar
  • Nominal pressure 16 bar
  • Max. pressure load one-sided overpressure protected up to nominal pressure, on (+) and (-) side of diaphragm, partial vacuum protected
  • Permissible ambient temperature 0 to +70°C
  • Max. storage temperature 70 °C
  • Protection class IP54 per DIN EN 60529
  • Linearity < 2% FS
  • Hysteresis < 1% FS
  • Output signal: 0/ 4-20 mA
