Today, modern building automation and HVAC technology intelligently match energy generation, energy distribution, air conditioning, and heat recovery to ensure that energy is used in a manner that saves resources and costs. The measurements are supplied by a large number of sensors for temperature, air humidity, pressure, and air flow in decentralized systems, machines, and rooms. With the help of this data, the automation system monitors, controls and regulates the technical systems. At a higher management level of building automation, all information is compiled and evaluated and the economical operation of the entire building is optimized.
First Sensor offers high-quality sensor solutions for building automation and HVAC systems that range from individual sensors to complex customer-specific sensor systems that help to boost the energy efficiency of heating, ventilation, and air-conditioning systems. We offer a range of sensor technologies for measuring minute differential pressures in air-conditioning technology and building automation. Our flow-based LME and LDE differential pressure sensors measure ultra-low pressures from 25 Pa (0.25 mbar) with ultra-high resolution and offset stability. Due to the minimal air flow through the flow channel integrated in the sensor chip, the sensors are highly resistant to dust. The membrane-based piezoresistive HCL and HCLA pressure sensors achieve exceptionally linear signal/pressure characteristic curves for measurement ranges from 2.5 mbar.
Comprehensive monitoring of a building also includes monitoring the building structure. Our precision MEMS inertial sensors detect the smallest changes in position or acceleration and thus help to detect and monitor structural changes, damage, and critical stress conditions on buildings.
