To avoid cross force influences the strain ring should be mounted at least 1 up to 1.5 times D (D =

nominal tie bar diameter) away from the force transmission. Be aware of moving platens and tools.

To analyse the sensor signal we recommend using a suitable instrument from Baumer

Sensopress.

Please note that from the pressing on the strain gauges a zero point offset can occur. The

instruments from Baumer Sensopress have an appropriate reset circuit. Load and unload the tie

bar 2 to 4 times under full load in order to exclude setting errors.

During operation, the sensor must be reset after each cycle. We have matching amplifiers

available.

Place the strain ring around the tie bar at the

desired location and tighten it slightly and

evenly with the two M8 cylinder head screws.

Do not move the strain ring on the tie bar!

Please take care that the ring does not

rotate during the mounting process.

The metal foils may be damaged and the

strain gage misaligned. Measuring

abnormalities may occur.

Make sure that the two slots between the strain

ring halves have the same dimensions. The

screws can be equally tightened with a torque

of 3Nm.

A too small torque may cause measuring faults

and a too big torque may cause permanent

damage to the strain ring.

The strain ring is now ready for operation and

the corresponding cables can be connected.

Only two strain gauges are led out of the strain

ring (passive element). The bridge completion

to a full bridge happens externally.

4 Removal

A strain ring can be mounted and removed several times without affecting the accuracy of the

measuring results (up to 100 times).

Loosen the screws evenly and remove the

strain ring carefully. Now remove consecutively

both strain ring halves from the tie bar.

Do not move the closed strain ring on the tie

bar! Please take care that the ring does not

rotate during the dismounting process.

The metal foils may be damaged and the

strain gage misaligned. Measuring

abnormalities may occur.
