The perfect sensor made with expert know-how

1 Electronics
Danfoss pressure sensors come with digital electronics and offer unique technical parameters in the following areas:

• accuracy
• operating temperature range
• protection in the area of electromagnetic and RF interference
• various sensor function modes
  • pressure measurement
  • pressure measurement and switching

2 Sensing element
Thanks to Danfoss offering two sensing technologies, it can cover versatile application requirements
and offer highly competitive solutions. Both technologies are designed for operation in several different environments:

• Piezoresistive semiconductor technology covers pressure ranges from 1 to 600 bar. This technology is available in absolute or relative versions
• Thin-film technology is mainly used in high-pressure applications up to 2200 bar. This technology is available only in a relative version.

3 Housing
The construction of the sensors ensures their stable operation throughout their lifetime thanks to the following features:

• high resistance to shocks and vibrations
• high degree of protection (special versions up to IP 69K)
• shock-limiting solutions preventing hydraulic shocks and cavitation. A
• all wetted parts are made of stainless steel. B
