Pressure sensor MS5534 by AMSYS

Pressure sensor MS5534

The MS5534 pressure measurement 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 MS5534 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.

MS5534-CM: protected by a metal ring filled with silicon gel on a ceramic hybrid 9x9mm (outdoor applications)
Pressure range: 0.15 … 16 PSI abs.; operating temperature: -40 … +125°C

MS5534-CP: protected by a plastic cap and one drop of silicon gel on a ceramic hybrid 9x9mm
Pressure range: 0.15 … 16 PSI abs.; operating temperature: -40 … +125°C

The MS5534-C is fully software compatible to previous versions (MS5534-A and MS5534-B)

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

Accessories for the MS5534

Also available are sample boards, which can be used together with the USB Development Kit to quickly evaluate the sensors and build prototypes, as well as light and dust protection caps.
