absolute pressure sensor MS5535 by AMSYS

absolute pressure sensor MS5535

The MS5535 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 MS5535 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. The MS5535 is protected by a metal ring filled with silicon gel on a ceramic hybrid 9x9mm for a pressure range: 0 … 200 PSI abs. and working within an operating temperature: -40 … +125°C.

Variants of the MS5535

MS5535C: Pressure range absolute 0-14 bar (burst pressure up to 30 bar)

MS5535-30C: Pressure range absolute 0-30 bar (burst pressure up to 50 bar)

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

Accessories for the MS5535

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.
