Honeywell RSC Series: TruStability™ High Resolution Board Mount Pressure Sensors

Honeywell is pleased to introduce its TruStability™ Board Mount Pressure Sensors, RSC Series, a high-end, high-value addition to its TruStability™ portfolio. The RSC Series is designed for applications that require higher performance than existing TruStability™ products. When compared to Honeywell’s existing TruStability™ sensors, the RSC Series provides greater than 18 bits of real resolution and a Total Error Band that is four times tighter while utilizing the same small, stable package. The Series is a more cost-effective than premium laboratory grade devices.

The RSC Series integrates proven sense element technology and stable packaging used in the TruStability™ platform with Honeywell’s innovative 24-bit analog to digital converter. Rather than having one-size-fits-all internal math, compensation co-efficients are stored in internal EEPROM, which provides flexibility because customers can customize compensation for specific applications.

VALUE TO CUSTOMERS
•  Enhances performance:  Output accelerates performance through reduced conversion requirements and direct interface to microprocessors
•  Enhances reliability: High burst pressures promote system reliability, minimize downtime, and can simplify design
•  Easy to design in: Package is small when compared to many similar sensors, occupying less area on the PCB
•  Low power: Reduces system power requirements and enables extended battery life

FEATURES AND BENEFITS
•  Pressure range:  ±1.6 mbar to ±10 bar | ±160 Pa to ±1 MPa | ±0.5 inH2O to ±150 psi; absolute 1 bar to 8 bar | 15 psi to 150 psi
•  Pressure types:
- Absolute:  internal vacuum reference and output value proportional to absolute pressure
- Gage:  referenced to atmospheric pressure and provides output proportional to pressure variations from atmosphere
- Differential:  allows measurement of pressure between two pressure ports
•  Total Error Band: As low as 0.25%FSS
