The DSCUSB strain gauge to USB converter is a compact, high performance strain gauge digital signal conditioner with USB connectivity aimed at applications which require high-accuracy measurement repeatability.
A rugged ABS IP50 enclosure makes this USB load cell converter suitable for all environments. Simply by plugging the DSCUSB into a PC, data can be extracted from most strain gauge bridge input sensors and acquired by software which allows data manipulation removing the need for amplifiers, filters & multimeters. No additional power supply is required as the power is drawn from the USB bus.
Although ideal for 1 to 1 interface, the strain gauge to USB converter – DSCUSB, can connect with multiple sensors with the use of a suitable hub. Available in ASCII protocol, offering higher resolution and lower temperature drift.
Ideal for all strain gauge bridge based sensors including load, weight, force, torque, pressure & displacement, the device simply plugs into your PC where data can be acquired and manipulated by accompanying software.
Typical applications for the DSCUSB USB load cell signal converter will be those requiring simple sensor connectivity in desk top settings such as test & measurement, R&D and laboratory environments.
An optional temperature sensor module (DTEMP) is available which will enable an advanced 5-point temperature compensation of measurements.
The USB load cell signal converter is also available as OEM pcb modules - please see product sheet for more information.

- DSCUSB Toolkit : Version 4.1.1 This toolkit allows configuration, calibration, logging and parameter management of the DSCUSB, DSCSUASC and DSCSUEASC modules.
- DSC 24 Channel Logging : Version 1.1.7 View and log data from up to 24 DSC, DLC or DSCUSB modules.
- Driver DLL DSCUSB : Version 1.1 DSCUSBDrv.DLL is a standard Windows DLL that can be used to help your own Windows PC applications communicate with DSC USB instruments DSCSUASC and DSCSUEASC.
- DSC Fixed COM Ports : This software ensures that all DSCUSB modules plugged into the PC are allocated the same COM port. This is useful for OEM scenarios where many modules are connected for production purposes.
- Instrument Explorer : Version 2 build 2.0 This software allows the user to quickly set up and start to use the digitisers and indicators that Mantracourt offers. Capabilities include event monitoring and data logging, as well as calibration and configuration.

- Q: How do I communicate with the USB device?
A: Using a simple ‘Virtual Com Port’, the DSCUSB communicates as if the device is connected to a serial port. The device addressing allows up to 127 devices. The ASCII version allows for continuous output stream.
- Q: Is temperature sensing available on the DSCUSB?
A: An optional temperature sensor module (DTEMP) is available which will enable an advanced 5-point temperature-compensation of measurements.
- Q: Is there Linearity compensation in the DSCUSB?
A: Advanced 7-point linearity compensation available as standard.
- Q: Is there adjustable sensitivity?
A: The DSCUSB is supplied pre-configured for standard 2.5mV/V full-scale strain gauges. A single additional resistor re-configures the input between 0.5 and 100 mV/V full-scale.
- Q: How stable is the DSCUSB device?
A: 25ppm/°C basic accuracy (equates to 16 bit resolution).
- Q: What is the DSCUSB calibration process?
A: Completely drift-free, adjustable in-system and/or in-situ via standard communications link. Two independent calibration stages for load cell and system-specific adjustments. Programmable compensation for non-linearity and temperature corrections. Calibration data is transferable between devices for in-service replacement.
- Q: Are there self-diagnostics capabilities?
A: Continuous monitoring on the DSCUSB for faults such as strain overload, over/under-temperature, broken sensors or unexpected power failure. All fault warnings are retained on power-fail.
- Q:What are the output options of the DSCUSB?
A: We currenly only offer the device in ASCII protocol.
- Q: Tell me about DSCUSB low current
A: Functions as a ‘Low Power Device’ i.e. draws less than 100mA (one unit load) when connected to a 350 Ohm Bridge.
