Introduction

Honeywell Basic Board Mount Pressure Sensors, including the TBP series and NBP series, are designed for food-grade and non-food-grade potential medical and industrial applications. These unamplified piezoresistive silicon pressure sensors provide a 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 system-level temperature calibration, making the sensors easier to integrate into systems, reducing part-to-part variation, and offering 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 wish to perform their own compensation, calibration, and amplification to take full advantage of the maximum resolution of the raw sensor output and utilize any algorithm required by the 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 OEM applications. They are suitable for non-corrosive, non-ionic gases such as air and other dry gases, and when the gel coat option is selected, also for non-corrosive, non-ionic liquids. All products are designed and manufactured to ISO 9001 standards and are NSF certified. Specific configurations carry food-grade certification. Contact the factory for food-grade options.

Features

• Compact package size down to 7mm × 7mm [0.276 in × 0.276 in]
• Operating temperature range: -40°C to 125°C [-40°F to 257°F]
• Reflow mount per J-STD-020E, MSL Level 2; rapid stabilization after reflow soldering, allowing immediate post-mount calibration
• Media compatibility options: non-gel-coated media channel — 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
• Silicone gel-coated media channel — same materials used in wet media channel, with silicone-based gel coating for condensation protection, 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

Applications

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