Compensated unamplified board mount pressure sensors

April 29, 2014 // By Graham Prophet
Honeywell Sensing and Control’s basic board mount pressure sensors are compensated and unamplified; the TBP Series is designed for users who require a simple, high quality, cost-effective, basic performance, mV-output sensor, to apply their own amplification while retaining maximum resolution.

Small size and numerous package options simplify placement on crowded PC boards; a wide pressure range allows for use in applications requiring higher pressures; and low current consumption allows for use in battery applications.

The TBP Series, used to measure gauge pressures, may be used in medical applications including hospital beds, oxygen concentrators, wound therapy and blood pressure monitoring; and industrial applications such as HVAC transmitters, air movement control, environmental control, leak detection, pneumatic controls and other commercial applications.

Gauge pressure sensors are referenced to atmospheric pressure and provide an output proportional to pressure variations from atmosphere. They are intended for use with non-corrosive, non-ionic gases, such as air and other dry gases, and for non-corrosive, non-ionic liquids when the silicone gel coating option is selected. The TBP Series are designed and manufactured according to ISO 9001 and are ROHS compliant.

The TBP Series Basic Board Mount Pressure Sensors offer a wide pressure range (1 psi to 150 psi, 60 mbar to 10 bar, 6 kPa to 1 Mpa), an operating temperature range from -40 °C to 125 °C and a 0 °C to 85 °C compensated temperature range. Their size of 7 x 7 mm is very small when compared to most board mount pressure sensors, simplifying installation. The TBP Series have an unlimited shelf life after the packaging is opened, can be calibrated within one hour after reflow solder, and are compatible with modern lead-free, no-clean solder processes.
