Card connects strain gauge devices straight to PC

A Celsum Technologies product story
Edited by the Engineeringtalk editorial team Jul 23, 2003

The DSC digital strain card is a cost-effective, highly accurate, compact and robust conditioning amplifier for strain gauge devices such as a load cells, pressure transducers and torque sensors.

The DSC digital strain card is a cost-effective, highly accurate, compact and robust conditioning amplifier which will allow a strain gauge device such as a load cell, pressure transducer or torque sensor to be connected to a computer or PLC system without the need for an expensive A/D card.

All that is needed is a 12V DC power supply, and a strain gauge device with an impedance from 320 to 1200ohm.

The DSC is available in RS232 and RS485 serial communications formats, with a choice of protocols from ASCII, Modbus, Mantrabus and CANOpen.

The device has an integral temperature sensor, and may be programmed for multistage linearity and temperature compensation.

The resolution may be selected from 19bit (1 part in 500,000) at a speed of 1Hz to 15bit (1 part in 30,000) at 100Hz, with low noise and high stability.

RS485 versions may be individually addressed on the same bus.

Two easy-wire junction boxes simplify field installation: the DSJ1 will accept one DSC card, and the DSJ4 will accept up to four of the RS485 versions.

An evaluation kit is available, with a DSC of the user's choice.

The devices carry a three-year manufacturer's warranty, and can normally be delivered from stock.
