Huba 401 Series – OEM Differential Pressure Transmitter


  • Special development for optimize of combustion mixture in gas boilers
  • With the special diaphragm geometry inherently stable due to homogeneous manufacture 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)

Huba 401 Series, this pressure transmitter utilizes a distinctive ceramic lever technology, ensuring reliability. Its sensor signals are temperature-compensated and adjusted, providing a voltage output (VDC). This amplified, linear signal is ideal for seamless integration into electronic control systems, facilitating direct processing.
