SLA2X is an unit suitable for the connection with capacitance and ultrasonic level transmitter. It display the input analog variable and depending of model, it can provide 2 or 4 relays. Each threshold can be programmed with different kinds of hysteresis. Two analog exit 0÷10V and 4÷20mA, and RS232 or MODBUS serial port are available again depending of the model. Designed to be mached with 4-20mA transmitter, it is specially used to be directly connected to TC22, TC26 e TC30 capacitance level transmitter, furthermore the ultrasonic transmitters 2-wire METER can be powered directly from the SLA2X. A special function allows a remote self-calibration facility; it can memorized empty-situation by press a pushbutton and the level-condition (from 20 to 100%) pressing another pushbutton. This function can help during the calibration when using capacitance transmitter and is not easy to change the level from 0 to 100% as riquired from capacitance transmitter. The level measurement can be converted into volumes or weights, and an optional linearization system can convert to engineering units a level not commensurate with the volume.
