Important Note:
This MPX Pressure sensor features no marking. Please check the images and the datasheet provided to ensure, that this is the right model for your application.
The bag it was supplied with reads: MPX100GUP. However there is no such part number information available to us. Comparing the datasheets it is most likely that it is an MPX100D pressure sensor from the MPX100 series. 

MPX100GUP Pressure Sensor (Manufactured by Motorola, Inc.)
Product Overview:
The MPX100GUP is a high-accuracy silicon piezoresistive pressure sensor. Manufactured by Motorola, Inc., this sensor provides a linear voltage output proportional to the applied gauge pressure, making it ideal for industrial, automotive, and medical applications.
Key Features:
Pressure Range: 0 to 100 kPa (0 to 14.5 psi)
Output Type: Gauge (relative to atmospheric pressure)
High Accuracy: Excellent linearity and repeatability
Uncompensated Sensor: Requires external temperature compensation and calibration
Ratiometric Output: Output voltage scales with supply voltage
Compact Design: Small form factor for easy integration
Applications:
Pump and motor control
Robotics and automation
Level sensing
Medical diagnostics
Pressure switches and control systems
Environmental and barometric monitoring
Packaging and Shipping:
Condition: Unused New Old Stock (NOS)
Each MPX100GUP sensor is securely packed in antistatic packaging to preserve its pristine condition and ensure safe delivery.
Note:
All specifications are based on standard laboratory conditions (25°C, 50% RH) unless otherwise noted.
