    The DSCUSB-PT USB potentiometer interface is a single-channel USB interface designed to convert potentiometer sensor outputs into a digital USB serial input.  It is very compact and housed in a rugged plastic case rated to IP50 making it suitable for all indoor environments.  It is ideal to use with our range of Micro-Epsilon draw-wire sensors of which Applied Measurements are an approved distributor.

    The DSCUSB-PT potentiometer interface plugs directly into your PC and requires no additional power supplies, as it derives all its power requirements directly from the USB bus.

    The potentiometer digitiser interface utilises the ASCII protocol and features high resolution to 1 in 200,000, 7-point sensor linearisation and high speed measurements at rates up to 100 readings/second.

    PC-based calibration of the USB potentiometer interface is very easy to perform using the DSCUSB-PT Toolkit software which is supplied free of charge.  The potentiometer signal can be read directly from the sensor or input numerically using figures from the sensor calibration certificate.  Other features includes linearization and temperature compensation.

    The free Toolkit software also features a data logging function that allows the user to log data to a spreadsheet compatible CSV file at rated up to 100Hz.

    Below you can download the DSCUSB Toolkit software which allows calibration and configuration of the DSCUSB-PT potentiometer interface module along with monitoring and data logging.  There is also a link to download the DSCLog24 which provides up to 24 channels of live monitoring and data logging, allowing multiple DSCUSB-PT modules to be used simultaneously.

    If you require a strain gauge signal to be converted to USB, try our DSCUSB USB load cell interface instead.
