Meaureman has 20 years rich experience in the measuring of pressure, temperature, flow, level industries, The “Measureman” branded products are the combination of continuous good quality and affordable price. “Measureman” products are selected and designed by professional engineers.

Description:
The MPXV7002 series piezoresistive transducer in the small outline package (SOP) is a state-of-the-art monolithic silicon pressure sensor.
It’s designed for a wide range of applications, and particularly those employing a microcontroller or microprocessor with A/D inputs.
This patented, single element transducer combines advanced micromachining techniques,
Thin-film metallization and bipolar processing which provide an accurate,
High level analog output signal that is proportional to the applied pressure.
In addition, with an offset specifically at 2.5V instead of the conventional 0V.
This new series allows to measure pressure up to 7kPa through each port for pressure sensing,
but also for vacuum sensing (refer to the transfer function in the data sheet for more detailed information).

Specification:
-2 to 2 kPa (-0.3 to 0.3 psi)
0.5 to 4.5 V Output
Weight: 0.1oz; 4g
