    SSW70

    The SSW70 series SMART level switches are microprocessor based instruments with an ON/OFF output signal. They can be remotely configured by a universal hand held terminal (HHT) or by PC with a dedicated interface.
    Moreover, it is possible to configure locally the instruments (set threshold) by means of 2 push buttons and to display the current measured level on the display.

    Description

    LEVEL SWITCH SERIES SSW70

    The SSW70 switches series can measure liquid level, density and interface level in closed or open vessels. They convert buoyant force exerted by a displacer immersed in a liquid to a proportional current signal thanks to a mechanical force transmission device based on a torque tube and a piezoresistive sensor.
    The Spriano® measuring cell contains the sensor and transmits the level value to the electronics. Thermal drift is compensated using the temperature signal generated by a PTC thermistor integrated in the sensor itself. Based on these readings the microprocessor generates a standard ON/OFF signal output, shows the measurement on the display and command a contact depending by a set threshold.
