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 reduces the need for periodic temperature calibration at the system level, simplifying sensor integration and minimizing part-to-part variation. It also offers multiple pressure signal resolutions, with a compensated temperature range of 0°C to 85°C [-32°F to 185°F]. The NBP series is uncompensated and unamplified, suited for customers who prefer to perform their own compensation, calibration, and amplification to take full advantage of the maximum resolution of the raw sensor output and apply any algorithm required by the application; it likewise offers multiple pressure signal resolutions. These products are available in a variety of package styles and mounting options to facilitate integration by equipment manufacturers. They are compatible with non-corrosive, non-ionic gases such as air and other dry gases, and — when the silicone gel coating option is selected — also with non-corrosive, non-ionic liquids. All products are designed and manufactured to ISO 9001 standards, are NSF-certified, and specific configurations carry food-grade certification.

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]
• Reflow mounting per J-STD-020E, MSL Level 1; rapid stabilization after reflow soldering, ready for immediate post-mount calibration
• Media compatibility options: Without gel coating on media path, inlet port limited to non-corrosive, non-ionic media such as dry air and gases; must not be exposed to condensing environments; gases limited to media compatible with high-temperature polyamide, silicone, alumina ceramic, silicon, gold, and glass. With silicone gel coating on media path, same wetted materials apply, but silicone-based gel coating protects against condensation, suitable for applications where condensation may occur
• Sensor materials for certain specific configurations have been tested and certified to the following food safety standards (applicable to specific configurations only): NSF-169, BPA-free, LFGB

Applications

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