DR3419 High-Accuracy Precision Pressure Transmitter with Temperature Compensation
The $15,000 Rework That Started with a False Reading
Our hydraulic press was cycling slower. The gauge read normal pressure, but every part was out of spec. Over three months, we accumulated $15,000 in rework costs and lost 40 hours of production time. The culprit? A false pressure reading that masked a gradual drift in the system. This experience taught us that even a small error in pressure measurement can cascade into significant financial losses.
Why Temperature Swamps Pressure Accuracy
Pressure sensors are fundamentally temperature sensors. Without proper compensation, a 10°C ambient shift can introduce errors exceeding 1% of full scale. In our lab, the temperature varied by 15°C daily, causing the original sensor to drift unpredictably. Consequently, the displayed pressure seemed stable, but the actual force applied to parts varied. This means that even a high-accuracy sensor can mislead if it lacks robust temperature compensation. Therefore, for critical applications, a temperature compensated pressure sensor is not optional—it’s essential.
How DR3419 Solved Our False Reading Nightmare
We replaced the faulty sensor with the DR3419 Precision Pressure Transmitter. This precision pressure transmitter boasts 0.05% accuracy, which is ten times better than our previous sensor. Moreover, its low total error band ensures that accuracy holds across a wide temperature range. The installation was straightforward, thanks to the variety of electrical and pressure connections available. As a result, we achieved consistent readings immediately.
80% Reduction in False Readings: The Measurable Impact
After installing the DR3419, false readings dropped by 80%. Rework costs fell to near zero, and production uptime increased by 15%. The key specifications—high accuracy 0.05% FS, excellent long-term stability, temperature compensation, low total error band, and versatile connections—made this possible. In fact, the sensor’s long-term stability means we can trust the readings for years without recalibration.
