Because of the dynamic and ever-changing nature of our customers’ needs, what we know as “The Ashcroft Way” is critically important to our operation and our process. While many of our products and technologies are born from proactive research and trying to get out in front of future problems, a lot of our work is reactive and comes from listening – our customers have problems, and they need instruments to help solve them.
Our engineers developed Silicone MEMS sensor technology that performs in low-pressure environments, specifically cleanrooms and isolation rooms (hospitals, clinics, etc.). This technology sets our instruments apart both because of their composition and their design, and think of it this way: any opening of a door or small change in the room will change the pressure reading – if you have too much pressure, you can’t open the door. That’s why accuracy, reliability, and stability are so vital. Precision is required in these applications.
Ashcroft Global Technical Product Leader Dave Dlugos believes this technology is “top of its class,” and he authored an exclusive whitepaper which can be downloaded HERE.
“Silicon diaphragm sensors using the differential capacitance principle of operation have the advantage of a perfectly elastic diaphragm and are better able to handle overpressure and pres-sure spikes. By virtue of the extremely small size and low mass, (Silicone MEMS sensors) are far less position-sensitive than larger and heavier metal diaphragms,” Dlugos writes in the paper. “Since they are dead-ended sensors, they can be used in critical/isolation and leak detection systems. However, because they are offered in very low ranges, they will also meet the requirements of most applications.”
