8 Ways DR3411 Industrial Pressure Sensor Transformed VFD Noise Signal
8 Ways DR3411 Industrial Pressure Sensor Transformed VFD Noise Signal
The $25,000 Scrap Problem That Started with a Slower Hydraulic Press
Our hydraulic press was cycling slower. The gauge showed normal pressure, but every part failed quality checks. On that night shift, I traced the issue to a faulty pressure transmitter that couldn’t handle VFD noise. This hidden problem cost us $25,000 in scrap and rework before we found the real culprit.
What SCADA Didn’t Tell Us About Our VFD Noise
Variable frequency drives (VFDs) create common-mode noise that couples onto any adjacent conductor. This noise corrupts the signal from pressure transmitters, causing erratic readings. Consequently, the press cycled slower, and parts were out of spec. Shielded cable helps, but it wasn’t enough. The noise was still coupling through the sensor’s internal electronics.
How DR3411 Solved Our VFD Noise Problem
After testing various transmitters and finding their performance lacking, we installed the DR3411 Industrial Pressure Sensor. Its onboard EMI filtering removes noise before it leaves the sensor head. Specifically, the DR3411 is designed with excellent electromagnetic anti-interference, making it ideal for VFD environments. It also features a heavy-duty design for industrial use, high overpressure capability, a variety of process connections, and long-term reliability.
$25,000 Saved: The Quantifiable Impact of EMI-Resistant Pressure Sensing
With the DR3411 in place, the hydraulic press started cycling normally, reducing our downtime by 50%. Moreover, the quality of the parts improved dramatically, saving us $25,000 in scrap costs and rework. In fact, the investment paid for itself within weeks.
