  • Pressure Sensor Can Create More Accurate Pressure-Controlled 3D Printers

    Los Gatos, CA, March 15, 2022 - Superior Sensor Technology today announced their System- in-a-Sensor architecture, NimbleSense™, offers manufacturers a precise, low-pressure measurement solution to improve accuracy and performance of 3D printing by enabling development of pressure-controlled 3D printers.

    Pressure sensors can improve 3D printing in several ways, including verifying the nozzle continues to flow material at an exact rate, confirming the correct pressure is being applied by the arm during construction and ensuring structural soundness of the object.

    “The 3D printer market is growing at over 20% CAGR, providing speed and flexibility in both-industrial and consumer markets,” said Mark Vena, CEO and Principal Analyst at SmartTech Research. “By offering manufacturers the ability to develop pressure-controlled 3D printers with advanced pressure sensor technology, innovative solutions like Superior Sensor will enable a new generation of devices that are more accurate and less wasteful.”

    Incorporated into the company’s ND Series product family for 3D printers and other industrial applications, the NimbleSense architecture enables the sensors to operate at unprecedented low noise levels, which maximizes the accuracy of 3D printers. The pressure sensors also include the company’s patented Multi-Range™ technology, closed loop control and advanced  digital filter features, which can further improve the precise operating capabilities of 3D printers.

    “3D printing or additive manufacturing has significant cost advantages. However, improved performance and accuracy are imperative for 3D printers to become mainstream industrial manufacturing instruments,” said Anthony Gioeli, Vice President of Marketing, Superior Sensor Technology. “Our NimbleSense technology is making it easier and more cost effective to develop pressure-controlled 3D printers that build objects with accurate disposition and structural integrity.”

    For example, consistent material flow through the 3D printer nozzle will ensure accurate material placement when building an object. The pressure required by the nozzle varies depending on the object being constructed and type of material flowing through the nozzle. Multi-Range allows a single sensor to support multiple pressure ranges, which allows the sensor to change the pressure of the nozzle “on-the-fly” to meet the pressure requirements for that particular object.

    The integrated closed loop control feature improves the responsiveness of the printer’s pressure sensing mechanism, by controlling motors, valves and actuators that drive the nozzle, arms and other parts of the 3D printer. By integrating the advanced digital filtering feature into the sensor, exterior noise is eliminated before it can lead to inaccurate pressure readings.

    The ND210 is an ideal pressure sensor for 3D printers, as it supports differential pressures as low as 62.5 pascal to as high as 2500 pascal - ensuring high accuracy for a wide array of materials and structures. In addition, its position insensitivity will not impact accuracy by any movements in the arm or nozzle.

    Superior Sensor Technology is revolutionizing the high performance, cost driven pressure sensor market by developing integrative, highly intelligent solutions for industrial, HVAC and medical applications. The company’s technology is based on a breakthrough system-in-a- sensor, proprietary architecture, called NimbleSense™, which significantly improves overall sensor performance while adding exclusive application specific system features. Superior Sensor Technology was founded in 2016 and is based in Los Gatos, CA.

  • SP Series
    Designed for Spirometers, SP Series of pressure sensors have extremely high accuracy. Multi-Range technology enables each device to support 4 pressure ranges, and unique Z-Track technology eliminates zero drift and the need for calibration....

  • Superior Sensor Technology’s SP Series low-pressure sensor module family uses NimbleSense™ — a proprietary architecture attaining a very high-level dynamic range — to develop the industry’s best-performing Spirometry pressure-sensing device.

    This broad dynamic range is perfectly suited to provide accurate near-zero measurements for supporting the demanding functional necessities of the Spirometry market. Now, selectable multiple pressure ranges are supported in a single package. The SP110/SP210 can be user-programmed to full-scale ranges of ± 250, 500, 1 k and 2.5 kPa whereas the SP160 can be programmed to ranges of ± 5, 10, 20 and 40 kPa.

    To simplify customer integration efforts considerably, the SP Series family offers a new sensor integration level into the Spirometry market that combines a superior piezoresistive sensing element with DSP, ADC, integrated amplification and processor intelligence. Floating point technology is leveraged by the SP Series to offer an exceptionally accurate digital output.

    When this precision is combined with the enhanced zero point and the best positional immunity of the industry, the ultimate in Spirometry system sensing performance is enabled. Performance, system cost and reliability are optimized by the SP Series for the competitive Spirometry market.

    Industry Leading Accuracy Performance

    The SP Series measures the pressure of dry air and non-aggressive gas with exact precision better than 0.10% of the selected range. It also exhibits an industry-leading Total Error Band, which is usually better than 0.15% FSS.

    In addition to industry-leading accuracy and positional insensitivity, the SP Series also include a proprietary Z-Track™ feature that practically eliminates zero errors. Power-on time is another important consideration, and with Z-Track™, warm-up time is substantially decreased, thereby making the SP Series a great choice for time-critical installation applications.

    Additionally, Spirometry devices must function flawlessly in crowded RF environments created by a confluence of wireless transmitters. This RF immunity requirement drives the need for special design effort to be put into the product packaging. This is done to minimize the effects of spurious RF signals on the sensor module performance. The SP Series has undergone proprietary design techniques to enhance the EMI immunity, reducing the influence of close proximity EMI producing devices such as WiFi, Bluetooth and other cellular communication protocols.
