The differential pressure transmitters of type 403 are outlined for the optimization of calorific values in gas fired heating systems. All materials used are compatible with burnable gas. In combination with the differential pressure transmitter type 401 a electronic airgas-compound can be realized. 

 

The type 403 series pressure transmitters, with its unique proven ceramic lever technology, has adjusted, temperature-compensated sensor signals, available as a voltage output. The (VDC) voltage output is an amplified, linear signal suitable for direct processing in electronic control systems.

 

Special features:

• Pressure range: 0 ... 3 - 8 mbar

• Special development for optimize of 

  combustion mixture in gas boilers

• With the special diaphragm geometry 

  inherently stable due to homogeneous 

  manufacture with the with the 

 2 component injection moulding process 

  (plastic silicone)

• Ideal dimensioning for high sensitivity 

  and with long term stability

• Excellent repeatability even in the lower 

  pressure range (< 20 Pascal)
