KP160Dif D411

Kapselfeder-Standardmanometer für Differenzdruck Typ D4

Variants Documents

  • Measurement of extremely small differential pressures
  • robust design
  • static pressures up to 400 mbar
  • direct indication of the differential pressure
  • many customised versions available

For differential pressure measurement of non-corrosive, gaseous, dry media. Especially suitable for filter loss measurement in air conditioning and ventilation applications.
! For measuring gas or vapour, observe the table "Selection Criteria as per EN 837-2" (see appendix)!

Type

Nominal size
160 - 160
Function
The "plus" pressure (= high pressure) is applied to the inside of the diaphragm. The "minus" pressure (= low pressure) is applied to the inside of the pressure-tight housing. The pressure difference causes the diaphragm to change its shape, thus generating the movement required to measure the pressure. This displacement is picked up by the movement. The differential pressure is directly indicated by a pointer.
