Introduction

Honeywell's basic board mount pressure sensors, including the TBP series and NBP series, are designed for potential medical and industrial applications in both food-grade and non-food-grade environments. These unamplified piezoresistive silicon pressure sensors provide ratiometric output; the TBP series is temperature compensated, while the NBP series is uncompensated. The TBP series is temperature compensated and unamplified — the compensation function reduces the need for periodic system-level temperature calibration, simplifying integration into systems and reducing device-to-device variation. It also offers multiple pressure signal resolutions, with a compensation temperature range of 0°C to 85°C [-32°F to 185°F]. The NBP series is uncompensated and unamplified, making it typically the ideal choice for customers who prefer to perform their own compensation, calibration, and amplification to fully utilize the maximum resolution of the raw sensor output and apply any algorithm required by their application. It also offers multiple pressure signal resolutions. These products are available in a variety of package styles and mounting options to facilitate integration into applications by device manufacturers. They are suitable for use with non-corrosive, non-ionic gases such as air and other dry gases, and also with non-corrosive, non-ionic liquids when the silicone gel coating option is selected. All products are designed and manufactured in accordance with ISO 9001 standards, are NSF certified, and specific configurations are food-grade certified.

Features

• Package size as small as 7mm×7mm [0.276 in×0.276 in]
• Operating temperature range: -40°C to 125°C [-40°F to 257°F]
• Compliant with reflow soldering standard J-STD-020E, MSL 1; fast stabilization after reflow soldering, allowing immediate post-mount calibration
• Media compatibility options: Without gel coating on the media path, input port is limited to non-corrosive, non-ionic media (e.g., dry air and gases); must not be exposed to condensing environments; gases must be compatible with high-temperature polyamide, silicone, alumina ceramic, silicon, gold, and glass. With silicone gel coating on the media path, the same materials are used in wet media paths, but condensation is prevented via silicone-based gel coating, suitable for applications where condensation may occur
• For specific configurations, sensor materials have been tested and certified to the following food safety standards (applicable to specific configurations only): NSF-169, BPA-free, LFGB compliant

Applications

• Medical: blood pressure monitoring, hospital beds, oxygen concentrators, wound therapy
• Industrial: air movement control, environmental control, HVAC transmitters, industrial control, leak detection
