Kromschroeder KFM250RB100 (03200109) pressure gauge

Kromschroder KFM250RB100 indicating pressure gauge, 0–250 mbar, 03200109 — a high-precision measuring instrument with a capsule element, designed for visual monitoring of static pressure of natural gas, LPG (in gaseous phase) or clean air in industrial gas supply and heating systems. The model with a 100 mm dial diameter and 0–250 mbar range is designed for low pressure measurement and is most often used on gas burner trains for fine adjustment and visual monitoring of gas pressure before supply to the combustion chamber. Failure of the standard pressure gauge (stuck pointer, loss of tightness, inaccurate readings) prevents correct burner adjustment, leading to excessive fuel consumption, unstable combustion and emergency shutdowns. Technical specifications Parameter Value Part numbers 03200109, KFM 250RB100, 624.466.003 Manufacturer Kromschroder / Honeywell (Germany) Device type Indicating pressure gauge (indication only) Working medium Natural gas, LPG (propane-butane), biogas*, clean dry air Measuring range 0 – 250 mbar (0 – 0.25 bar) Visible dial diameter 100 mm Accuracy (class) 1.6 (per EN 837-3), permissible deviation ±0.6% Connection Brass, thread G ½" B Mounting position Horizontal Protection degree IP54 (dust and splash proof) Housing material Stainless steel Medium temperature from -20°C to +60°C Zero adjustment Yes (adjustment screw) Dimensions (L x W x H) 140 x 100 x 50 mm Weight 0.453-0.483 kg Service life 10 years *For biogas operation, a special seal is required. ✅ Key advantages High-precision low pressure measurement: Thanks to the capsule measuring element, this pressure gauge provides high accuracy (class 1.6) precisely in the low range of 0-250 mbar, where standard Bourdon tube gauges are ineffective.
