32347489 Issue B DPR SERIES TruStability Board Mount Pressure Sensors Standard Accuracy, Compensated/Amplied 1.6 mbar to 25 mbar 160 Pa to 2.5 kPa 0.5 H O to 10 inH O 2 2 DESCRIPTION POTENTIAL INDUSTRIAL The TruStability DPR Series is a APPLICATIONS piezoresistive silicon pressure sensor Heating, ventilation, air conditioning offering a ratiometric analog output for (HVAC) reading pressure over the specified full Variable air volume (VAV) control scale pressure span and temperature Damper control and duct air flow range. These sensors are fully calibrated Filter monitoring/clogged filter and temperature compensated for detection sensor offset, sensitivity, temperature Modulated furnace controls effects, and non-linearity using an on- Indoor air quality board Application Specific Integrated Leak detection Circuit (ASIC). Calibrated output Pneumatic control values for pressure are updated at Burner control approximately 1 kHz. The DPR Series is Fuel-to-air rationing calibrated over the temperature range Gas analyzers and meters of -20C to 70C -4F to 185F . Fume hoods and clean rooms The sensor is calibrated for operation FEATURES from a single power supply of 5.0 Vdc. Pressure range: 1.6 mbar to 25 mbar These sensors measure differential 160 Pa to 2.5 kPa 0.5 inH O to or gage pressures. The robust and 2 10 inH O durable housing, with its industry- 2 Pressure types: Differential and gage standard mounting configuration, Total Error Band: As low as 1.25 %FSS along with a choice of flexible electrical depending on pressure range (after terminations, is designed to withstand auto zero) tough application environments. The Accuracy: 0.25 %FSS BFSL (Full sensors internal diagnostic functions PORTFOLIO Scale Span Best Fit Straight Line) detect most internal failures, including Honeywell offers a variety of Stable offset voltage burst sensors, and may reduce the board mount pressure sensors for Compensated temperature range: need for redundant sensors in the potential use in medical and industrial -20C to 70C -4F to 158F system. The DPR Series is intended applications. Our categories of Low sensitivity to mounting orientation for use with non-corrosive, non- pressure sensor measurement include Output: analog voltage ionic gases, such as air and other dry absolute, differential, gage or vacuum Overvoltage and reverse polarity gases. Custom calibrations, additional gage, with unamplified or amplified protected pressure ranges or options to extend the sensors and covering a wide pressure Industry-standard mounting performance of these sensors to include range.

TABLE 4. SENSOR PRESSURE TYPES PRESSURE TYPE DESCRIPTION Differential Output is proportional to the difference between the pressures applied to each port (Port 1 - Port 2). Gage Output is proportional to the difference between applied pressure and atmospheric (ambient) pressure. FIGURE 1. TEB COMPONENTS FOR TRUSTABILITY FIGURE 2.
