Made by Motorola, these were made to measure pressure ranges that you would find in medical devices (up to 300mm Hg). We are not sure of the exact pressure range spec on this one but it is similar to the MPX2011DT1 or MPX2301DT1 sensors. They all have the same hookup. These are based on piezoresistive technology. The case is the white plastic chip PAK and is only 0.38" tall x 0.26" wide x 0.10" thick. Has small fitting with a black colored gel inside for mounting to your hose. The size of this fitting is 0.123" diameter. The sensor is brand new on tape and reel. They are marked with a customer specific number (not the part #). The hookup is pin 1 Vcc, pin 2 (+) out, pin 3 (-) out, pin 4 ground. Sorry no other details available but there is schematics, app notes, etc on the internet for similar sensors. Great experimenter item for building pressure sensing or pressure activated devices.
