Sensors-pressure switches TERMOBREST DRD, DRD-N, DRD-T, etc.

The pressure switch sensor (DRD) is designed to monitor the overpressure (head) and vacuum pressure (thrust) of gas media in gas supply and ventilation systems. They are used to control pressure deviations beyond the maximum and minimum values.

DRD series Diaphragm type (overpressure control):
- maximum operating pressure: up to 1500 mbar (1.5 bar);
- controlled pressure ranges from 3 to 1000 mbar;
- output signal: dry contact.

Membrane type of the DRD-N series (overpressure control):
- maximum operating pressure: up to 1500 mbar (1.5 bar);
- ranges of controlled pressure in the range: from 0.6 to 1000 mbar;
- output signal: dry contact.

---

DRD-T series diaphragm type (vacuum pressure monitoring):
- maximum operating pressure: up to -50 mbar;
- controlled pressure ranges from -0.6 to -50 mbar;
- output signal: dry contact.

---

Electronic type of the DRD-E series (overpressure control):
- maximum operating pressure: up to 9000 mbar (9 bar);
- controlled pressure ranges from 0.5 to 6000 mbar;
- output signal: current (4...20 mA), relay, visual (LED).

---

Electronic type of the DRD-E...T series (control of vacuum pressure):
- maximum operating pressure: up to ±105 mbar;
- controlled pressure ranges from -70 to 70 mbar;
- output signal: current (4...20 mA), relay, visual (LED).

---

Electronic type of the DRD-16 series (overpressure control):
- maximum operating pressure: up to 16000 mbar (16 bar);
- controlled pressure ranges from 100 to 16000 mbar;
- output signal: current (4...20 mA), relay, digital (RS-485 interface), visual (4-digit digital display).
