Product Description:

SDP1000-L05 HVAC Application 0-125Pa Flow And Pressure Sensor

Features:

Sensirion differential pressure and flow sensors adopt the thermal measurement principle. Place the controllable heating element at the center of the pressure stabilizing membrane, and then install the temperature sensor symmetrically at both ends of the upstream and downstream of the heating element along the direction of liquid flow. The liquid flowing through the film causes heat to be transferred to the downstream temperature sensor, generating a temperature difference and thus forming a measurable and precise signal. The pressure-stabilizing glass passivation film is installed onto the silicon chip by etching to integrate the micro-thermal flow sensor.

Compared with traditional piezoresistive film sensors, CMOSens gas flow sensors have more advantages in low-speed flow and differential pressure sensitivity, deviation drift and lag, position sensitivity, shock resistance and temperature fluctuation, and support bidirectional measurement.

The chip contains a temperature sensor whose signal can compensate for any possible temperature influence without the need to install additional calibration sensors. Therefore, Sensirion's technical solutions not only save space but also offer extremely high cost-effectiveness. In addition, a digital processing circuit and a storage unit are integrated on the digital chip for storing correction data. All Sensirion sensors are individually calibrated during the production process to ensure that the signals are always fully calibrated, linearized and temperature-compensated.
