MPT500 is an ultra-small and ultra-light aerospace pressure sensor with a 24mm body length and only 13g weight. While it fits most standard test environments, extreme 50mm limited installation space required structural customization. By adopting an external amplifier solution and completing full defense metrology certification, we helped a research institute successfully replace traditional Kulite sensors under strict aerospace project conditions.
What challenges did the client face?
An aerospace research institute originally planned to use Kulite pressure sensors for engine bench tests.
Long lead times and high costs made the client look for reliable domestic alternatives.
Their test rig only had 50mm installation space. The standard MPT500 came with a built-in amplifier, which was too long to fit.
Besides, the project required valid third-party defense metrology certification, a mandatory standard for aerospace applications.
How did we deliver the tailored solution?
Our engineering team moved the amplifier to an external module. The sensor body length was cut to around 20mm, fitting perfectly within the 50mm space.
The customized sensor passed full third-party calibration and obtained official defense metrology certification.
We delivered the qualified prototype within 4 weeks, causing no delays to the client’s test schedule.
“The external amplifier design lets us install the sensor without adjusting our test rig. The defense metrology certificate fully meets our project rules. Its performance is identical to Kulite sensors.”

On-site test performance
The customized MPT500 worked steadily during bench tests. It reaches 0.1% FS accuracy and 400kHz frequency response, with an operating temperature range from -55°C to 125°C. All technical parameters match Kulite specifications.
The sensor ran continuously for over 200 hours with zero signal drift or faults.
The third-party defense metrology certification was fully approved by the client’s team.

FQA
Can the MPT500 pressure sensor be customized for limited installation space?
Yes. The standard MPT500 pressure sensor features an ultra-compact body length of only 24mm and weighs just 13g, lightweight and mini enough to fit most conventional test rig installation scenarios. For a few extreme ultra-narrow installation environments like the 50mm limited space in aerospace test equipment, we can further customize it with an external amplifier design to shorten the mounting size perfectly, meeting strict space constraints for aviation, aerospace and satellite application scenarios.
Does the customized MPT500 support defense metrology certification
Yes. All our aerospace-grade pressure sensors can undergo third-party official calibration and obtain defense metrology certification, fully compliant with scientific research, military, and aerospace project requirements.
Is the customized MPT500 performance consistent with Kulite sensors?
Yes. After customization, the MPT500 maintains 0.1% FS high accuracy, 400kHz frequency response, and stable wide-temperature performance, fully matching the technical indicators of traditional Kulite sensors for engine bench testing.
What are the advantages of choosing Dabey customized sensors over imported Kulite sensors?
We provide flexible size customization, faster delivery cycles, lower overall costs, and complete third-party certification support, solving long lead time and high-cost pain points of imported sensors for research institutes.
Can you modify sensors with external amplifiers for other space-constrained projects?
Yes. External amplifier customization is a mature solution. We can adjust sensor body length, diameter, and interface structure according to different test rig space limits for aerospace and industrial testing scenarios.
