    7. 3D level monitoring system – monitors level, volume, mass of materials in a silo or open bin- non-contact method The system monitors the level of material in a silo or container. The material can be solid (e.g. power or grain) or liquid (e.g. chemicals). The transducers or microphones scan and map the whole area using beamforming techniques – similar to ultrasound or sonar. Low frequency pulses are sent and the echoes are received from the contents. The processor works on the time of arrival and direction of the received pulses (GLP = General Level Processor). With the processing algorithms used a 3 dimensional map is produced. The volume and mass of material can be derived and can be displayed in various ways.

Remote temperature monitoring is normally also included (see temperature monitoring signal chain in 2H09AIE Green Energy them for an example).

    9. Signal chain description The LF transducers are switched from input to output by the low RON ADG884 analog switches, effectively acting as transmit/receive (TX/RX) switches; the transducers are quite low impedance (about 8 ohms). In transmit mode the signal pulses are bandpass filtered and fed to a low noise amplifier (LNA) – ADA4841. The LNA provides outputs at a suitable level for conversion in the AD7923 200 KSPS, 12 bit, 4 channel ADC. The digitised transducer outputs can now be processed by the ADSP-BF534 Blackfin DSP (the customer calls this a GLP in his application , general level processor). The DSP can output suitably processed information (including the level of material, temperature , pressure etc.) to an LCD display. The AD5228 digital potentiometer controls the display contrast. The DSP also provides suitable transmit waveforms via the AD5601 DACs to excite the transducers in TX mode. The SSM2250 audio amplifier produces a sufficient amplitude for these pulses to be applied via the ADG884 as the excitation source for the transducers. The system also contains a HART modem which runs over a standard 4-20 mA loop; the AD421 loop powered DAC performs this function. An ADM6713 processor supervisory chip monitors the DSP, acting a reset generator during power up/down or if the supplies fall below a workable threshold. The power supplies themselves use ADP121, ADP1715 and ADP1710 linear regulator ICs.

    10. The ADG884 is used because a low RON is essential when the transducers have low impedance; they also have to handle quite high currents. The typical on resistance of the ADG884 is only 0.1 ohms. The ADG884 is used because a low RON is essential when the transducers have low impedance; they also have to handle quite high currents.

    18. Primarily Analog Communication Digital Communication is also possible Digital data can be modulated on top of the 4-20mA current using FSK (Frequency Shift Keying) HART (Highway Addressable Remote Transducer) On a 4-20mA loop only one parameter can be transmitted and only in one direction, HART digital communication enables the transmitter to transmit multiple parameters (multivariable transmitters) And also allows the transmitter to be controlled from the control room enabling remote calibration and diagnostics. HART uses an FSK scheme with 1200 Hz representing a 1 and 2200 Hz representing a 0. The great majority of modern transmitters would include HART capability.

    19. Adding HART communication capability This circuit shows how HART capability can be achieved with an ADuC706x ,an AD421 and a HART modem. For transmission The HART modem accepts a bit stream from the controller and converts it into an FSK signal which is Then applied to the AD421, the AD421 modulates the FSK signal onto the loop. For reception the modem takes the FSK signal from the loop, converts it into a bit stream Which it sends to the controller, implementing half duplex communication between the transmitter and the control room. Further details are available in Application Note AN-534. This circuit shows how HART capability can be achieved with an ADuC706x ,an AD421 and a HART modem.
