Strain Gauge USB Converter (DSCUSB)

The DSCUSB USB strain gauge converter is a compact, high performance strain gauge digital signal conditioner with USB connectivity aimed at applications which require high-accuracy measurement repeatability.

Strain Gauge USB Converter (DSCUSB)

A rugged ABS IP50 enclosure makes the device suitable for all environments. Simply by plugging the device 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.

Although ideal for 1 to 1 interface the device 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 signal converter will be those requiring simple sensor connectivity in desk top settings such as test & measurement, R&D and laboratory environments. No additional power supply is required as the power is drawn from the USB bus. Although ideal for one-to-one interface, the device can connect with multiple sensors with the use of a suitable hub.

Communications (USB)
The load cell to USB adaptor will communicate as a simple serial device rather than a ‘native’ USB device.
Once the device is plugged into a PC and the supplied drivers are installed, the device will appear as a Virtual Serial Port to the PC.
Standard Modbus drivers, configurations and libraries can be used with this device. Mantracourt will also supply a driver for its own ‘Instrument Explorer’ software.
Because each device, when plugged into a PC, creates an additional serial port, the total number of devices that can be attached to the PC may be limited by the communication software’s ability to utilise these multiple ports i.e. an existing Modbus communication program may only support COM1 to COM4.
