    Closed Loop Control with Data Acquisition Systems
    Design Note 13
    Guy Hoover and William Rempfer
    Introduction
    The use of microprocessors in process control loops
    is quite common. A processor based control loop requires special design considerations as compared to
    traditional analog loops. Often a single centrally located
    processor will be used to control several remotely
    located processes. The outputs of the remote process
    sensors can be digitized at the sensor location and then
    be transmitted to the central processor. Unfortunately,
    transmitting digital signals typically requires one wire
    for each bit of resolution and requires expensive cabling.
    Alternatively, the sensor output can be transmitted
    as an analog signal to the central processor area for
    digitization. However, transmitting analog signals over
    distances can introduce errors because of noise and
    voltage drops in the wires.
    The solution to these control loop problems can be found
    in the LTC ®1090 series of data acquisition systems. As
    can be seen in the schematic of Figure 2, ten bits of
    data can be digitized remotely and sent to the processor
    with only three wires plus ground. The single supply ...

    A Two Wire Isolated and Powered 10-Bit Data Acquisition Sytem
    Design Note 19
    Guy Hoover and William Rempfer
    Introduction
    For reasons of safety or to eliminate error producing
    ground loops, it is often necessary to provide electrical
    isolation between measurement points and the microprocessor. Unfortunately, the isolated side of this measurement system must still be provided with power. One
    alternative is to power the isolated side of the circuit with
    batteries. This solution works if power consumption is
    low, environmental conditions are mild and the batteries
    are easily accessible. If these conditions are not met a
    separate isolated supply may be constructed. This can be
    both difficult and expensive. This design note describes
    a transformer isolated system in which one small pulse
    transformer provides both power and a data path.
    The circuit of Figure 1 is a 10-bit data acquisition system
    with 700V of isolation. The circuit takes advantage of the
    serial architecture of the LTC ®1092 which allows data
    and power to be transmitted using only one transformer.
    A 10-bit conversion can be completed and the data transferred to the microprocessor in 100μs. Using standard
    ribbon cable the isolated side of this circuit has been remotely located as much as 50 feet from the transformer
    without affecting circuit performance.

    Temperature Measurement Using Data Acquisition Systems
    Design Note 5
    William Rempfer and Guy Hoover
    Introduction
    Accurate temperature measurement is a difficult and
    very common problem. Whether recording a temperature, regulating a temperature or modifying a process
    to accommodate a temperature, the LTC®1090 family
    of data acquisition systems can provide an important
    link in the chain between the blast furnace temperature
    and the microcontroller. Features of the LTC1090 family
    can make temperature measurement easier, cheaper
    and more accurate.
    High DC input resistance and reduced span operation
    allow direct connection to many standard temperature
    sensors. Multiplexer options allow one chip to measure
    up to 8 channels of temperature information. Single
    supply operation, modest power requirements (~5mW)
    and serial interfaces make remote location possible.
    Switching power on and off lowers power consumption (560μW) even more for battery applications.
    Finally, because few sensors have accuracies as good as 0.1%, the 10-bit resolution and 0.05% accuracy of
    the LTC1090 family are just right for most temperature
    sensing applications.
