Product Description
1 Summary
The ZKMD-6857D pressure sensor adopts a DIP like packaging form. The pressure sensor core and signal processing circuit chip are bound inside the housing to digitally compensate for the sensor's offset, sensitivity, temperature drift, and nonlinearity. With the power supply voltage as a reference, a calibrated signal is generated
Standard digital signal after temperature compensation.
The ZKMD-6857D pressure sensor has a small size and is easy to install, widely used in medical electronics, automotive electronics, consumer electronics, and sports and fitness
Equipment, Internet of Things, and other fields.
