Kromschroder Indicating manometer KFM160RB100 03200124

The Kromschroder KFM160RB100 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 0–160 mbar, a dial diameter of 100 mm, and an accuracy class of 1.6 (deviation ±0.6%). The device features a stainless steel housing, IP54 ingress protection, and a G 1/2" B connection thread. It operates within an ambient temperature range of -20 °C to +60 °C, weighs 0.57 kg, and has dimensions of 140 x 100 x 49 mm. The service life is 10 years.

When selecting a replacement manometer of this type, ensure the measuring range, connection thread, and size match the original. The working pressure should sit near the middle of the scale for optimal accuracy. Verify the wetted materials are compatible with the medium (e.g., gas or oil). Mounting position and ingress protection should also be considered, as some models require horizontal installation or specific protection ratings.

Common failure modes include a stuck pointer, loss of seal, or inaccurate readings. These issues can prevent correct burner adjustment, leading to fuel overconsumption, unstable combustion, or emergency shutdowns. Check that the pointer returns to zero when the system is depressurised and that the glass or window is intact.
