Block diagram MS5540C
DESCRIPTION

The MS5540C pressure measurement miniature module consists of a SMD-hybrid device including a piezoresistive pressure cell and an ADC-Interface IC. It provides 16 Bit data words from a pressure- and temperature-dependent voltage. Additionally the module contains 6 readable coefficients for a highly accurate software calibration for the pressure and temperature measurement. The MS5540C is a low-power, low-voltage device with automatic power down (ON/OFF) switching. A 3-wire interface is used to communicate with a microcontroller.

The devices have a very low standby-current. The optimal compromise about refresh rate and average current consumption can individually be defined by the application software.

MS5540-CM: protected by a metal ring filled with silicon gel on a ceramic hybrid 6.2x6.4qmm
Pressure range: 10...1100mbar (0.15 ... 16 PSI) abs.; operating temperature: -40 ... +85°C
The MS5540-C is fully software compatible to previous version MS5540-B.

As accessory available:
  • USB Development kit for quick evaluation of the pressure sensors
  • Light and dust protection caps with or without connector

*Modules are pressure sensors, whose output signals have to be calculated by an external microprocessor
