Evaluation Kit for Differential Pressure Sensors

Sensirion, the world’s leading manufacturer of high-quality humidity, gas and liquid flow sensors, offers advanced EK-P4 Evaluation Kit, which simplifies the evaluation of Sensirion’s differential pressure sensors even further. The kit combines all the features required for test measurement, including a flow element, so first measurements can be made cost-effectively and exceptionally quickly. The evaluation kit consists of a USB stick connected to a PCB on which an SDP3x differential pressure sensor is already attached. The flow element can be easily affixed to the kit with two screws and then directly connected to the gas flow. The viewer software, which can be downloaded from the Sensirion website, shows the measured differential pressure using a graph. It allows simple data logging and the export of measurement data in the form of an Excel list. The SDP3x tested with the kit is the world’s smallest differential pressure sensor and measures a mere 5 x 8 x 5 mm. The SDP3x’s flow measurement is based on the thermal measuring principle, which is characterized by particularly precise measurement and long-term stability. It is free from zero point drift, which eliminates the need for regular zero calibration.
