Of Pinched Piezo Cables Signal Drift

At a recent customer visit we were testing the tool on the bench. We were pushing on pins while watching values on the Cycle Values screen and noticed one changing when we were not touching it. The value was continuously going down.The cause? A pinched piezo...

Visual Fault Detection for Piezo Sensors

In tip 164 we mentioned how the electronics do not automatically detect sensor problems for piezo sensors like they do for strain gage. Howerver the data provide useful indications if a piezo sensor is having problems.Zero pressureIf the sensor reads zero pressure...

Piezo Sensors Do Not Detect Disconnects

It’s all in the title.Some of our customers have thought that because our Lynx Piezo sensors have the integrated case electronics that they would behave the same as the strain gage sensors in detecting disconnections or broken wires. This is not true. When a piezo...

Be Kind to Your Sensors: Load ’em True

In recent weeks we have had some reports of sensor installations not up to standards. Specifically these were cases where the sensor was not supported or loaded on its center line. Like the three-legged stool, sensors will not work if you don’t have symmetrical...

No negatives on stroke scaling, please

“Always with the negative waves, Moriarty…”        ( from…? )A customer found a way to confuse an eDART™ by entering a negative number in the scaling for the stroke analog input (from the machine). If you are taking injection stroke from the machine instead of the...
