Why Bulky Pressure Transmitters Don’t Fit in Compact Machinery
Compact Pressure transmitter solutions for demanding industrial applications. The DR3403E series delivers reliable performance.
Every week at our Detroit manufacturing facility, pressure readings would drop 20% when the VFD ramped to full speed. The process was steady; the signal was lying. After months of troubleshooting, we traced the issue to VFD-induced electrical noise overwhelming the transmitter’s electronics. The space constraints on our OEM panels left no room for standard transmitters without costly redesign.
We investigated the DR3403E, a compact pressure transmitter designed for tight spaces. Lab tests confirmed the problem wasn’t contamination but the transmitter’s inability to reject VFD noise. The DR3403E’s robust stainless steel construction and high-performance pressure sensing solved it. Response time improved by 50%, and thermal drift dropped 20%. The standard 4-20mA output integrated seamlessly, while the wide operating temperature range ensured reliability.
Why the DR3403E Works
VFDs generate common-mode noise that couples into signal lines. The DR3403E uses a shielded sensor element and differential measurement to reject this noise, maintaining accuracy within ±0.25% FS even near VFDs.
