Verschildruk-transmitter DE46 met LCD van Fischer

Differential pressure transmitter – DE46

Supplier: Fischer

The DE46 from Fischer has no difficulty in accurately measuring very small pressure differences. With a measurement range starting from 0..25 Pa, an optional digital transmitter output, and a clear LED display, even the smallest pressure changes are detected, including in ATEX zone 2/22 environments.

The DE46 is equipped with a capacitive sensor and can measure both positive or negative atmospheric pressure as well as differential pressure. The pressure is measured using a silicone-glass differential capacitive sensor element. Pressure changes result in a proportional capacitive change corresponding to the applied pressure. The microchip processes the signal and sends it to the LED display, the relays, and the 4-20 mA analog output.

Advantages

  • Suitable for measuring low pressure (differences) of gases, with no long-term drift
  • Robust design; overpressure protected and maintenance-free
  • Transmitter signal output (optional)
  • Suitable for ATEX zone 2 / zone 22 (optional)

Applicability

The DE46 from Fischer is particularly suitable for building automation applications, including air conditioning and ventilation systems, filter monitoring, and use in clean rooms and laboratories.
