Pressure is one of the most frequently measured parameters in industrial process control applications. SmartMeasurement’s ALDPT series of pressure transmitters may be configured to measure absolute pressure, gauge pressure or differential pressure and is also available in a muti-variable configuration that is capable of simultaneously measuring temperature and pressure. This level of versatility allows the ALDPT transmitter to be used in virtually any industry or application where pressure measurement is required.
Within the ALDPT Series there are five different types of instruments to accommodate the wide variety of applications that exist in industry. SmartMeasurement’s staff of experienced application engineers is available to help users select among these choices and specify the instrument that provides the best solution for any pressure measurement application.

Pressure measurement is the most widely measured variable in industrial process control applications. Pressure measurement is commonly performed in applications involving all media phases including liquid, gas, and steam. For example, in the oil & gas industry, wellhead pressures are measured in subsea and topside locations. In water towers, pressure is measured to monitor and control water levels. Pressure sensors are used to monitor the water line pressure in automatic sprinkler systems. Barometric pressure is used to predict the weather.
