    1 . Sensor Installation When the gap is filled with liquid, the piezoelectric receiver crystal converts the ultrasonic wave into an electrical signal, which is transmitted back to the control unit using a second coaxial cable. Usually the two coaxial cables to the sensor are in one overall sheath. The control unit circuitry is a feedback amplifier ...

    T wo cables are required per sensor . The RG178 should be used where the cable itself is subject to temperatures exceeding 74°C. 2 . Control Unit Installation All cable connections are made to the terminal blocks along the bottom edge of the pcb (see fig.5). Release the terminal screw before inserting the wire. 2.2 External Connections Protection ...

    2.3 Switch Settings in MCU200 Series (i) Gain switch (and potentiometer): See section 3. (ii) Frequency selection This slide switch is labelled “FREQ” and is located between the sensor terminal block E2, and the Aux input terminals. This selects the operating frequency of the MCU200 oscillator , which is either 3.7MHz (switch in the 'up&ap ...

    3.1 Gain adjustment Correct adjustment of the gain (HI/LO switch and potentiometer) is essential for proper operation of any ultrasonic sensor system. This adjusts the gain of the feedback amplifier in the control unit, which produces oscillation of the sensor when the coupling between the ultrasonic crystals is sufficient. Therefore the higher the ...

    3.3 Pump control and latching alarms The output relay of the MCU200 can be latched into the de- energised state. This latch is achieved by short circuiting the two terminals of the Auxiliary input, labelled as terminals 3 & 4 on the pc board (see figure 5). The relay will remain de- energised while the latching short circuit is applied. Only af ...

    3.4 Interface Detection 3.4.1. Suspended Solids blanket sludge discharge detection The Mobrey MCU200 control unit can be used in conjunction with a 433S sensor to provide sludge blanket level detection in a settling tank, facilitating the control of automatic desludging. Similarly , in conjunction with a Mobrey sludge pipe using a pair of 488S sens ...

    3.4.3. Interface detection between two immiscible similar liquids When liquids are ultrasonically very similar - as happens for example with paraffin and water - the procedure in section 3.4.2. produces very little difference between the two “false dry” points. In this case the “reflection” method of interface detection is used. If an ultra ...
