Digitale lagedruksensoren

The digital LDE-pressure sensors Sensor Technics have ranges from 25 Pa (0.25 mbar) measuring range limit. With a special compensation technology, the sensors reach an offset stability better than 0.1%. The flow-based differential pressure sensors make use of an internal microcontroller, digital signal generation and provide a high accuracy. There are both a digital SPI bus interface and an analogue output. The LDE sensors for air and gas are based on the sensitive, thermal mass flow measurement and deliver signals with high resolution.

The flow channel includes the measurement element is integrated in the chip. Due to such miniaturization at the chip level, the gas flow through the sensor units, more reduced as compared to normal flow-based pressure sensors. The LDE-differential pressure sensors are therefore insensitive to dust and moisture and can be used with long connecting hoses and filters, without the calibrated measurement accuracy is at stake.

It also requires no cumbersome housing structures, making the LDE sensors are small and inexpensive built and save space for mounting on printed circuit boards. The LDE-pressure sensors are suitable for precise and accurate measurements of long-term small pressure differences in devices in the field of medical technology and climate and measurement.
