Note: The 1139_0B is identical to the 1139_0, except that you have the option of which size of Phidget cable to include.
The 1139 Differential Pressure Sensor is a dual ported air pressure sensor that measures the pressure difference between the two ports. It can measure pressure from 0 kPa to 100 kPa.
This sensor is designed to measure the pressure of clean, non-condensing air. Contact with moist air (i.e, human breath), dusty air, or other gases can shorten the lifespan of the sensor.
This sensor can be read by any Phidget with an Analog Input or VINT Hub port. It will connect to either one using a Phidget cable. VINT Hub ports can behave just like Analog Inputs, but have the added flexibility of being able to be used as digital inputs, digital outputs, or ports to communicate with VINT devices. For more information about VINT, see the VINT Overview page.

This sensor requires a Phidget cable to connect it to an InterfaceKit or Hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system. See a full list of Phidget cables below.

This device doesn't have an API of its own. It is controlled by opening a VoltageRatioInput channel on the Phidget that it's connected to. For a list of compatible Phidgets with VoltageRatio Inputs, see the Connection & Compatibility tab.
You can find details for the VoltageRatioInput API on the API tab for the Phidget that this sensor connects to.
