Product Attributes

Introduction

The HV series family provides differential low-pressure sensors for HVAC applications. The series features multi-range capability, maintaining performance across a range from 60 inches water column to 0.1 inches water column. The architecture provides high dynamic range, enabling a single device to cover the full spectrum of HVAC pressure requirements. For example, a multi-range enabled device can replace multiple competing products, simplifying installation requirements and reducing inventory costs. The series integrates 50/60Hz notch filters to minimize the impact of power supply noise spikes. The series offers a new level of integration, combining advanced piezoresistive sensing elements with integrated amplification, ADC, DSP, and digital interfaces, simplifying customer integration efforts. Built with a high-reliability plastic housing, it provides an ideal combination of high performance and reliability, while ensuring customers have a cost-effective solution optimized for their HVAC requirements.
