Differential pressure transmitter 403 0 ... 3 – 8 mbar - 1

FOR FINE PRESSURE AND FLOW MEASUREMENT Pressure range 0 ... 3 - 8 mbar Type 403 pressure transmitters sense ultra-fine changes in gas pressure for use in air / gas ratio control systems. All materials used are compatible with flammable gas. When used in combination with our type 401 pressure transmitter, the optimum air / gas ratio can be achieved. Special development for optimize of combustion mixture in gas boilers With the special diaphragm geometry inherently stable due to homogeneous manufacture Ideal dimensioning for high sensitivity and with long term stability Excellent repeatability even in the lower pressure range (< 20 Pascal) Huba Control type 403 - Technical data subject to change - Edition 05/2018 1/4
