DSGA Bolt-On Strain Transducer FJ46

Where no load cell fits, the structure itself becomes the sensor: the DSGA is bolted to the machine through four holes of Ø 6.6 mm and reads the strain of the part it sits on. That makes it the instrument for large equipment – presses, frames, columns, cranes – and for every place where cutting a load cell into the force path is out of the question.

The measuring element is a full bridge on a stainless steel body of 89 × 25.4 mm, rated at 1.0 mV/V and available for 200, 500, 1000 or 1500 µε. It takes 5 to 10 V DC, tolerates 120 % of its range without harm and 150 % before it is destroyed, and it carries six metres of fixed cable, sealed to IP65. Mounting and replacing are a matter of four screws, and nothing in the force path has to be opened to do it.

Measurement
