PMP3700

Test sensors for aerospace
The amplified PMP3700 pressure sensors have been
specifically designed to meet the harsh test requirements
encountered in aerospace applications. These sensors arebased on the pedigree of the 3000 series flight qualified
product family, which has been hugely successful since
its launch in 2000. The PMP3700 sensors offer a highperformance (digitally characterised) sensor that can beconfigured to suit the customer’s specific requirement.
The products incorporate the unique Druck fabricatedsilicon, which is produced in our new 21st century Class 100clean room, providing unrivalled long term stability andperformance. The product is designed with aerospace inmind, offering a fully hermetically sealed device, with EMI andRFI protection.

Features• Absolute, gauge and sealed gauge options available• Standard accuracy of ±0.2% FS over the specified
temperature and pressure ranges• Stated accuracy includes the combined effects of nonlinearity, hysteresis, repeatability (NLHR) and zero/spansettings over the calibrated temperature range• Fully welded stainless steel construction• Hermetically sealedApplications• Accurate pressure measurements for use in aerospaceground and flight tests• Suitable for automotive test and many Industrial
applications
