Capacitive pressure sensor controller PCS07xx


 
 

        Description
The PCS07xx is a controller that integrates capacitive sensors and pressure sensors, which can not only detect liquid triggers by programmable capacitive sensing, but also judge whether the pipeline is blocked and leaking through the change of pressure value, and the two systems can operate independently. Both capacitance and voltage values can be converted into intuitive data outputs, and triggering can be determined by status bit changes and LEDs. The PCS07xx provides a simple and fast control command set, which can be connected to the control host via CAN, in a small size, cost-effective, one model, two uses, and a simple and flexible interface. It is suitable for reagent level detection and container level detection of various medical, environmental protection and laboratory instruments.

Model
Description
Single-end mode 1
This mode selects the detection channel 1 work

Single-end mode 2
This mode selects the detection channel 2 work

Single-end mode 3
This mode improves detection accuracy, suitable for reagent bottles or small volumes of liquid to be measured
The differential mode
This mode is non-contact measurement mode when the coupling capacitance of the equipment frame is very large
Sliding window mode
Sliding Window Mode, which is suitable for cases where capacitance values drift slowly or where the capacitance to be measured is very small, enables stable detection of capacitance trips down to 500fF, which is used superimposed on the four modes mentioned above
