Introduction

The HBP5023A-2 product series is an analog dual-nozzle differential pressure sensor. It features high accuracy, low power consumption, wide operating temperature range, and dual measurement capabilities for both pressure and temperature. Each unit is individually calibrated; offset, sensitivity, temperature drift, and nonlinearity compensation are all correctable via calibration coefficients. The HBP5023A-2 series adopts a barbed dual-nozzle SOP8 package, providing excellent sealing at the connection interface for ease of use and system integration. The product offers outstanding ESD robustness, fast response, high accuracy, high linearity, and long-term stability. All measurement data are fully calibrated and temperature-compensated. This product is widely used in medical devices, HVAC, fire safety, and sports equipment. Unless otherwise specified, all data in the table above were measured under the following conditions: measurement medium — air; atmospheric pressure (101325±500) Pa; temperature (25±2)℃; vibration < 0.1g (1m/s²); humidity (50%±10%); supply voltage (5.0±0.25) VDC. The typical output transfer function for the HBP5023A-2 series is given by Equation (1), where the pressure range is |P|min ~ |P|max, corresponding to a sensor output range of 10% Vdd ~ 90% Vdd, and an output voltage range of 0.50V ~ 4.5V (Vdd = 5.0V). The relationship between sensor output and applied pressure is: Vout = (80%Vdd / (|P|max - |P|min)) × (|P|read - |P|min) + 10% Vdd. Where: Vout is the output voltage in V; |P|max is the maximum pressure in Pa; |P|min is the minimum pressure in Pa; Vdd is the supply voltage in V; |P|read is the pressure to be measured in Pa. By applying different pressures, the output-versus-pressure curve can be plotted, and the sensor output exhibits a linear relationship with the applied pressure.
