Flow Measurement in Gas Boilers
Gas boilers are now more comfortable and environmentally sound. The efficiency of the boiler, as well as an increase in the modulation ration, can be achieved through precise measurement to a combustion chamber with the differential pressure sensor SDP800. The reliable and cost-effective sensor is the result of more than 15 years of experience, extending Sensirions expertise in the HVAC market.
Thanks to its compact size and flexible modification options, Sensirion's differential pressure sensor can be installed in any boiler. In addition, the proven sensor guarantees a wide dynamic control range, the elimination of zero-point drift, outstanding accuracy and the option of certified intrinsic safety.

The SDP800 sensors are based on the next generation CMOSens® sensor chip and build on the success of the SDP600 series. The SDP800 series are the reliable solution for measuring air flow in the most demanding but cost-sensitive applications. The main features are its reliability and long term stability, no offset and no zero-point drift. The Differential Pressure Sensor Series SDP800 are hysteresis free and have an excellent accuracy as well as repeatability, even below 1 Pascal. They are just perfectly suited for applications that require to measure the air flow with a high dynamic range. The main applications and devices for the SDP800 series are in HVAC, such as gas boilers, pellet stoves and fuel cell, filter monitoring, VAV control and ventilation, heat recovery systems.

Specialist Article: Efficient Gas Flow Measurements in Bypass
Measuring gas flow in applications requiring high precision and cost-efficiency is a challenge. Experience in recent years has shown that microthermal flow sensors are superior to other technologies. Industries with exacting demands have recognized that microthermal gas flow sensors give their products decisive advantages. These manifest themselves in high long-term stability and precision even when flow rates are minimal, and the sensors' suitability for cost-efficient and reliable mass production.
Where in the gas flow should a sensor be positioned? And how should the flow guide be designed to achieve the best-possible results while keeping the production processes simple? Experience with many of our customers' applications and endurance tests for product certification give a clear answer: In most cases a bypass configuration is preferable to placing the sensor in the direct flow.
