3.3. Principle of operation
Area of application
Principle of operation
The DT1010 xx xx Temperature / Resistance /
Potentiometer Transmitter provide signal transmission and
conversion between sensor or resistance / potentiometer
and signal processing unit.
The transmitter feature complete 3-way isolation: the input
to output and both to the power supply circuits are isolated.
The output signal may be:
0-20 mA, 4-20 mA, 0-10 V, 2-10 V.
The sensor / resistance / potentiometer can be connected to
the input either with 2 / 3 or 4 wire.
The module features complete configuration of sensor input
variables and process signal outputs.
Some of the configuration options are: sensor type,
resistance range, signal output scaling, 2 / 3 or 4 wire
measuring mode, signal filtering, calibrated sensor curve
fitting, etc. The configuration software is capable of storing
all the parameters for future re-configurations.
The configuration parameters are downloaded from
the PC to the DT1010 xx xx via USB port.
The measuring current flows through the sensor / resistance
/ potentiometer connected to the input. The voltage drop on
the measuring sensor is compared with the voltage drop on
the internal reference resistor. The voltage difference is led
to a 21 bit A/D converter. The digital output signal of the
A/D converter is processed by a microcontroller.
The microcontroller produces a pulse width modulated
output signal which is proportional to the processed, scaled
measuring value. The output pulse is galvanic isolated by
an opto coupler. After filtering the pulse is converted into
analogue current or voltage signal.
Connecting the instrument to the PC through the USB
interface the instrument’s communication circuitry come into
active state and it is ready for communication with the
configuration software.
Power supply The instrument works from a 19-35 VDC supply voltage.
The power consumption is 1.6 W.
