Verschildruktransmitter DE38 van Fischer

Differential pressure transmitter – DE38

Supplier: Fischer

The DE38 is a multifunctional pressure instrument from Fischer that combines a digital display, a transmitter, and two relays for limit value monitoring. It is a measurement and control system suitable for positive or negative atmospheric pressure, differential pressure, flow, and level measurement. The instrument’s range is from 0..400 mbar to 0..6 bar.

The DE38 operates based on a diaphragm that moves when a pressure difference occurs. When in balance, the springs on both sides of the diaphragm maintain equilibrium. The diaphragm is connected to an inductive displacement transducer, which converts the movement into a 4-20 mA electronic output.

Advantages

  • Sturdy construction – overpressure protection
  • No mechanical wear of the sensor element
  • Maintenance-free
  • Programmable via PC (optional with model EU03)
  • Adjustable units
  • Compatible with the DZ23 / DZ24 valve block

Applicability

The DE38 is a highly versatile instrument. It can be used for monitoring compressors, filters, and vacuum systems, as well as for measuring differential pressure in forward and return flow in heating systems. The system is suitable for measuring flow, pressure (differential pressure), or level.
