FUNCION CODIGO SECCION
Manómetro estandar tipo cápsula para presión diferencial 01-2001 01

Standard capsule type pressure gauges for differential pressure.

Application.

For differential pressure measurement of gaseous, dry media which are non-corrosive. Especially suitable for filter loss measurement in air conditioning and ventilation applications. When measuring gas or vapour, the instruments must be used in accordance with the safety recommendations of EN 837-2.

Type D 9/D 4
Nominal size 63 – 100 – 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 the pointer of the gauge.
Accuracy class (EN 837-3/6) 1.6
Ranges (EN 837-3/5)
NG 63 0/16 to 0/400 mbar
NG 100 0/ 6 to 0/400 mbar
NG 160 0/ 4 to 0/400 mbar
