Standard Bourdon tube pressure gauges RF100Dif | 85609201

Standard Bourdon tube pressure gauges for differential pressure type D2

manufactured goods
Documents

  • Indication of plus pressure, minus pressure and differential pressure
  • excellent price/performance ratio
  • two independent Bourdon tube systems
  • Housing and wetted parts also available in stainless steel (option)

For differential pressure measurement of gaseous and liquid media which are not highly viscous, do not crystallize and do not attack copper alloys. Specially suitable for heating systems (supply and return pipes).
! For measuring gas or vapour, observe the table "Selection Criteria as per EN 837-2" (see appendix)!

Type
D2
Nominal size
100 - 100
Function
The pressures are measured in two independent Bourdon tube systems ("plus" pressure = high pressure, "minus" pressure = low pressure). The pressure is indicated by means of a dial and a pointer. The differential pressure scale covers 50 % of the range of the "plus" pressure and 50 % of the range of the "minus" pressure. The black pointer ("plus" connection) and the red pointer ("minus" connection) at the differential pressure gauge scale allow you to read the pressures in both systems on the fixed scale.
accuracy class (EN 837-1/6)
1,6
ranges (EN 837-1/5)
see ordering table
application area
The maximum pressure in the system must not exceed the full scale value. For good readability, the differential pressure to be measured should not be less than approx. 20 % of the full scale value.
Operating temperature range
Medium:
max. 60 °C
Ambient:
-20/+60 °C
Temperature performance
Indication error when the temperature of the measuring system deviates from the normal temperature of 20 °C:
bei Temperaturzunahme ca. ± 0,4 %/10 K,
falling temperature approx. ± 0.4 %/10 K
