Honeywell TruStability ultra-low pressure sensors have three performance attributes difficult to achieve in the same product: high sensitivity with high overpressure and burst pressure.
The new sensors have an amplified compensated digital or analog output for reading pressure over the full-scale pressure span in the ultra-low pressure range of ±2.5 mbar to ±40 mbar [±1 inH2O to ±30 inH2O]. As a result, the units can address many low pressure industrial and medical applications including the more difficult clogged filter detection (industrial) and ventilators (medical).
The overpressure ranges are above 135 inH2O (336 mbar) and burst pressures are above 415 inH2O (1034 mbar) for these ultra low pressure units allowing them to handle a wide range of application conditions.
Using a Total Error Band (TEB) approach to specify the sensor’s accuracy over the compensated temperature range, users do not have to calculate the total effect of individual errors that could occur in their applications. The TEB for the HSC Series varies between ±1 %FSS and ±3 %FSS (depending on the pressure range), while the TEB for the SSC Series varies between ±2 %FSS and ±5 %FSS (depending on the pressure range).
Honeywell claims an industry-leading accuracy of ±0.25 % FSS BFSL (Best Fit Straight Line) for the new sensors.

I have worked in MEMS sensors for a long time. While I am retired now, I still do consulting work and product development. You can check on google. I have a design for a MEMS force-sensing die, which does not require a ball like your FSS-SMT Series and can also function as a joystick.
Honeywell might be interested since, unlike my contacts in OEM sensors, they are already in the force market.
Thank you,
