A micro-machined absolute pressure sensor, the BP20 provides a high-level voltage output signal that is proportional to absolute pressure.
#2046
The BP20 pressure sensor includes built-in temperature compensation, linearization, and an output amplifier. Its low cost and rugged ABS enclosure make the BP20 ideal for collecting absolute pressure data at remote sites.
