SPS71 Intelligent Pressure SwitchFeatures - High precision. - Adjustable response time. - NPN, PNP compatible, free switching and 4~20mA. - Button operation, shortcut button for zero calibration fast switching. - OLED shows current pressure - LED for node action, easy to observe Applications - Hydropower. - C hemical industry. - City water supply. - Scientific research - Accurate measurement and control of pressure of fluids SPS71 pressure switch is an intelligent digital product for pressure measurement and co n t rol wich integrates pressure measurement, display, output and control. Th e product is in full electronic structure. Piezoresistive silicon pressure sensor is adopted in the front end. The output signal is processed by the amplifier of high precision and low temperature drift, and then sent into high precision A/D converter. Through arithmetic processing by microprocessor, the output signal is displayed on site with 2-way switch output, accomplishing the measurement of the pressure of control system. SPS71 has advantages of flexible use, simple operation, easy commisioning and high safety and reliable. It is widely used in hidropower, tap water, petroleum, chemical, mechanical, hidraulic and other industries for the measurement, display and control of pressure fluids Sitron - Brasil Sitron - USA R.
