Imagine holding the linchpin of a complex monitoring system in the palm of your hand. Our Pressure Sensing Core has a weight and density that feels substantive—this isn't a fragile component. The stainless steel housing is cool to the touch, machined to a smooth, satin finish that resists fingerprints and minor handling abrasions. You can see the laser-etched markings, crisp and permanent, promising traceability and quality.
When you integrate this core into your system and power it on, there is no dramatic event, only the quiet assurance of a job being done perfectly. There is no audible click or hum; its "sound" is the silence of reliability. The electrical signal it produces is a clean, stable stream of data, a direct and faithful translation of mechanical force. This is the experience of eliminating a primary source of uncertainty in your design.
The inspiration for its ruggedized design came from a project with a client building agricultural drone systems. Their soil compaction sensors, exposed to constant vibration and humidity, were failing prematurely due to inadequate sensing cores. We re-engineered the isolation and packaging, leading to the hermetic sealing and robust construction you see here. This core was born from the need to perform not just in a controlled lab, but in the demanding, unpredictable real world. By choosing it, you are not just buying a component; you are incorporating a piece of proven field resilience into your product, saving your team from costly field failures and reputation damage.

Q1: What is the difference between the "Pressure Range" and "Withstand Pressure" specification?
The Pressure Range (e.g., 0-100kPa) is the span over which the core is designed to operate with its specified accuracy. The Withstand Pressure (e.g., 200kPa) is the maximum pressure that can be applied without causing a permanent shift in performance or mechanical damage. It is a safety margin. For your design, you should ensure that occasional system pressure spikes do not exceed the withstand pressure to guarantee long-term reliability.
Q2: How critical is the "Excitation Voltage" (5VDC) and what happens if we power it with 3.3V or 10V?
The excitation voltage is the reference for the core's internal Wheatstone bridge. Operating at 5VDC is critical because the core's sensitivity (output signal) is directly proportional to it. If you use 3.3V, your output signal will be 34% smaller, reducing your signal-to-noise ratio and effective resolution. Using 10V will double the output but will likely overheat the sensor, leading to significant measurement drift and potential long-term damage. Always use a stable, regulated 5VDC supply for optimal performance.
Q3: Our end product will be used in an environment with large temperature swings. How does the "Thermal Drift" specification affect us?
Thermal drift is one of the most critical specifications for real-world accuracy. Our cores are laser-trimmed for temperature compensation, minimizing the "Zero Drift" and "Span Drift" across the operating temperature range. This means that a temperature change from -20°C to +80°C will have a minimal, predictable effect on the reading. For high-precision applications, you can use the provided drift coefficients in your microcontroller to perform software compensation, effectively neutralizing the effect of temperature on your final reading.
Q4: Can this core be used to measure the pressure of aggressive media like chlorine or saltwater?
The standard isolation diaphragm is Stainless Steel 316L, which offers good resistance to many corrosive media, including weak acids, alkalis, and saltwater. However, highly aggressive media like chlorine, bromine, or strong acids may require an additional isolation barrier, such as a chemical seal. We recommend consulting the corrosion resistance tables for 316L stainless steel for your specific media and contacting our technical team to discuss your application. We can also provide cores with alternative diaphragm materials like Hastelloy for extreme applications.
