Coffee & Espresso Machines

Household coffee machines utilize pressure to control the brewing process and to purge the line once the coffee has been fully dispensed. This sensor should be small and robust against humidity and liquid to accurately drive the motor speed. SMI offers a variety of small and accurate pressure sensors that can be utilized for this application.

Espresso machines rely on accurate pressure and temperature to brew the perfect cup of espresso. These pressures can be quite high, with high temperature and humidity requiring a robust sensor. SMI manufactures sensors well suited to such applications operating up to 50bar and 150°C, that also have a small form factor.
