CPM121 Industrial Commercial Equipment Field Pressure Sensor Manufacturer
Pressure Sensor CPM121 Industrial Commercial Equipment Field Sensor Manufacturer
Product Description
The CPM121 system-in-a-package (SIP) solution comprises of aresistive bridge type pressure sensor and a 24-bit ADC for high resolution and accurate pressure measurements. The fully calibrated pressure and temperature compensated digital output makes the CPM121 solution simple to use.The CPM121 includes internal calibration logic that provides accurate pressure and temperature measurements to the application via the I²C interface.There is no need to separately download internal calibration coefficients and have the host microcontroller perform complicated compensation calculations.
