Products for USB Sensing and Control
4-20mA sensors can be connected to and powered by the provided terminals on this 4-20mA Adapter board. The 1132 will measure the current passing through the attached sensor and convert it to a voltage between 0 and 5V.
The 4-20 mA Adapter board internally produces +15V from the 5V supply which is used to power the connected sensor, eliminating the need for an external power supply.

This device doesn't have an API of its own. It is controlled by opening a VoltageInput channel on the Phidget that it's connected to. For a list of compatible Phidgets with Voltage Inputs, see the Connection & Compatibility tab.
You can find details for the VoltageInput API on the API tab for the Phidget that this sensor connects to.
This sensor can be read by any Phidget with an Analog Input or VINT Hub port. It will connect to either one using the included 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 comes with its own Phidget cable to connect it to an InterfaceKit or Hub, but if you need extras we have a full list down below. 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.
