Not only will these sense ultra low pressure changes, but they are able to function in high pressure environments. Quite a trick. Developers get high sensitivity with high overpressure and burst pressure. This technology protects the sensor without sacrificing the ability to sense very small changes in pressure, as well as provides high durability amid environmental factors such as temperature and humidity.
Honeywell – Ultra low pressure sensor family for medical & industrial applications.
The new Honeywell TruStability Ultra-Low Pressure Sensors perform substantially better relative to stability than any other pressure sensor available in the industry today, even after long-term use and thermal extremes. This quality minimizes system calibration needs, maximizes system performance, and helps support system uptime by eliminating the need to service or replace the sensor during its application life.
