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 repeat-ability.
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 & multi-meters. 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.

A: Using a simple ‘Virtual Com Port’, the DSCUSB communicates as if the device is connected to a serial port. The device addressing allows multiple devices.
A: An optional temperature sensor module (DTEMP) is available which will enable an advanced 5-point temperature-compensation of measurements.
A: Advanced 7-point linearity compensation available as standard.
A: 10ppm/°C basic accuracy (equates to 16 bit resolution).
A: Continuous monitoring on the DSCUSB for faults such as strain overload, over/under-temperature, broken sensors or power failure. All fault warnings are retained on power-fail.
A: We currenly only offer the device in ASCII protocol.
A: Functions as a ‘Low Power Device’ i.e. draws less than 100mA (one unit load) when connected to a 350 Ohm Bridge.
