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...

Always Ground Temperature Modules

We have discovered from time to time that customers find noise on their cavity temperature sensor signals. As noted in the install document it is critical that, when using a grounded thermocouple (as our TS-PF03-K sensor) the electronics that measure that sensor must...

Lynx Devices v.s. Channels

Some confusion has arisen concerning how many “things” are hooked to a Lynx port (two ports => Thing 1 and Thing 2, if you remember your Dr. Seus).The question is: If I hook up something like a Lynx Quad Temperature module is that 4 of the maximum 30...
