Kromschroder Indicating manometer KFM100RB100 03200108

The Kromschroder KFM100RB100 is an indicating manometer with a diaphragm measuring element, designed for visual monitoring of static pressure in gas supply and heating systems. It has a measuring range of 0–100 mbar, a dial diameter of 100 mm, and an accuracy class of 1.6. The device features overload protection and is housed in stainless steel with IP 54 ingress protection. It operates within an ambient temperature range of -20 °C to +60 °C and has a G ½" B connection thread.

When selecting a replacement manometer of this type, ensure the measuring range, connection thread, and dial size match the existing installation. The mounting position should be horizontal, and the device must be compatible with the medium (e.g., natural gas, LPG, or air). Verify the accuracy class and ingress protection rating as needed for the environment.

Diaphragm manometers can fail due to overpressure, causing permanent deformation or rupture of the diaphragm, leading to inaccurate readings or complete loss of indication. Condensation or moisture ingress may fog the dial or corrode internal components. If the needle sticks or does not return to zero, the mechanism may be damaged or clogged.
