Manometer MDD80
Description |
|
Mechanical manometer type MDD80 are used |
|
|
for direct visibility of pressure. They are working |
|
|
by the bourdon-tube measuring system. |
|
|
Those types are very robust because of special |
|
|
soldering and can be used until temperatures |
|
|
90/130°C without case of additional safety |
|
|
equipment like siphons etc. |
|
|
Those manometers can be used for many |
|
|
applications in district and house heating |
|
|
systems. |
|
|
They are resistent to different heating |
|
|
water qualities, which are in accordance with |
|
|
valid qualities rules (f.e. FW510, VDI2035) or also |
|
|
in DHW-systems (acc. german TWVO or similar). |
|
|
District heating manometers of type MDD80 |
|
|
produced in accordance with norm EN837-1. |
