Equipment responsible for thermal conditions inside buildings
Due to the current expectations and regulations in the housing construction industry, systems of mechanical ventilation with heat recovery are widely applied, i.e. those that in a way recycle heat from the polluted air removed outside. Temperature in the building is increased e.g. with the use of boilers powered by eco-pea coal, wood pellet fuel or gas, or alternatively with heat pumps, which have been growing in popularity in recent years. When the temperature gets too high, air handling units are used.
Industrial facilities, in which production processes may raise the temperature too high for people to bear it, require similar control. Sensitive electronic devices also need strictly defined conditions including air temperature, pressure or humidity to be maintained in order to work properly. Even minor changes may influence the service life of the components or the accuracy of the device performance.
In order to operate correctly, all those systems require suitable measuring instruments, which report the necessity of outside intervention such as device maintenance or checking the actual operating parameters. The ability to work of the heating, ventilation or air-conditioning systems mentioned above is largely dependent on proper air flow. Its intensity determines the operating power of the system. So, if the device is to work as stated in its data sheet, the SDP differential pressure sensors are needed as its inherent element.
The design of these sub-components includes two connection nozzles through which the gas flows. Two built-in sensors capture the temperature difference caused by different streams of the medium flowing through the nozzles. Thanks to this very temperature difference, the differential pressure in the system can be determined.
Main advantages of differential pressure sensors
- Differential pressure measurement, both in the positive and in the negative range;
- Small size thanks to which the reading can be conducted in compact devices;
- High reading sensitivity in the low pressure range;
- Reliability;
- Great accuracy of readings both in the low and relatively high pressure ranges.
Top-notch differential pressure sensors
The wide selection of products in the catalogue TME includes a range of reliable solutions manufactured by a Swiss brand Sensirion. High quality in addition to innovative, often out-of-the-box solutions in the field of pressure sensors have already been appreciated by even the most demanding customers. Sensirion currently has its branches in the US, China, Europe, Japan, Taiwan, and South Korea.
In order to present the main parameters of differential pressure sensors, it is worth looking at an example:
The measuring range of the SDP810-500PA pressure sensor powered with 2.7÷5.5V DC is -500÷500Pa. With a wide spectrum of permissible operating temperatures (-40÷85°C), the sensor can be installed even in the most demanding conditions, without the risk of damage or distorting the readings. Thanks to the compact size and nearly negligible weight (5.35g), the component is a perfect choice for virtually every application. The manufacturer guarantees high quality of the readings, long-term stability and reliability.
Sensirion products meet the rigorous requirements of the RoHS directive, which eliminates dangerous substances that are forbidden in the manufacture of electronical devices – as such, they contribute to the protection of the environment.
Ensure the accuracy of the reading with Sensirion
Successful control of environmental conditions depends on the quality of individual elements of monitoring system. Sensors are the first of those, so the quality and reliability of these components should be the deciding factor when it comes to choosing solutions for specific applications. Sensirion products meet the expectations and requirements for pressure sensors, ensuring accuracy and failure-free work.
