Product Overview
Temperature-Compensated Differential Pressure Sensor (Unused NOS)
This low-range silicon pressure sensor converts differential pressure into a stable millivolt signal for precision measurement systems. Designed for accurate sensing in 0–50 kPa / 0–7.25 psi ranges, it suits designs that add their own amplification. Practical tip: use short, equal-length tubing on both ports to minimize offset caused by installation effects.

Product Overview
The MPX2050DP is a monolithic piezoresistive silicon differential pressure sensor with factory trim for span, offset, and temperature effects. It delivers a low-level, ratiometric millivolt output proportional to applied pressure between its two ports. The dual-ported unibody SIP package supports differential or gauge configurations depending on how the reference port is connected.

Frequently Asked Questions
Does this sensor include an amplifier?
No. The MPX2050DP provides a calibrated millivolt bridge output and requires an external instrumentation amplifier.
Can it be used as a gauge pressure sensor?
Yes. Venting the reference port allows gauge pressure measurement relative to ambient pressure.
Why is the output ratiometric?
The bridge output scales with supply voltage, which helps maintain accuracy when the ADC uses the same reference.
What media is it intended to measure?
It is characterized for clean, dry, non-corrosive gases such as air.
You can measure low differential pressure in pump control systems by connecting both barbed ports with clean tubing and amplifying the ratiometric millivolt output using an instrumentation amplifier on a control board.
