Model SLX 220a & SLX 220b -Submersible Transducers
The SLX 220a and SLX 220b submersible transducers consist of two components; a level transmitter (i.e. the SLX 130-E) and a current transmitter (i.e. the T425 or T423 respectively).
The SLX 130-E provides a 0,5-4.5 VDC output over the sensor`s poressure range. The T425 and T423 provide the 5VDC (nominal) stable reference to excite the SLX 130-E. Further, the T425 and T423 convert the 0.5-4.5 VDC signal to a calibrated 4-20 mADC output. Both the T425 and the T423 contain SPAN and OFFSET potentiometers which allow the installing technician to adjust the T425/T423 output so that the signal meets the fie requirements as found in the field. Further, the T423, as foiund in the SLX 220b, provides an on-board simulation potentiometer which allows the field tech to simulate the tank`s level, thus reducing the necessity of a full tank of water for transducer calibration.
