The transmitters detect sensor signals by means of RTD temperature probes, thermocouples,
resistance transmitters, or resistors/potentiometers. When using a resistor/potentiometer or RTD
temperature probe, the sensor connection on the input side can be connected with a 2-wire, 3wire, or 4-wire circuit. Voltage signals in the range from -100 to +1100 mV can also be detected.
Depending on the selected measuring input the linearization variants linear, temperature-linear,
and the possibility of an easy configurable as well as customer-specific linearization are available.
Type 707050 delivers 4 to 20 mA as an output signal. Type 707051 offers an output signal of 4
to 20 mA or 0 to 10 V. The measuring input and the output signal are electrically isolated from
each other. Reversion of the output signal is possible for both types.
The transmitter configuration with respect to probe type, connection technology of the probe,
measuring range (freely adjustable), and linearization is carried out by means of a setup program
on the PC. The connection to the PC is established via a USB interface which does not require
additional auxiliary voltage. Via the USB interface the min./max. process value and the min./max.
operating temperature detected by the transmitter can be read and the sensor wiring can be
checked online.
The operating status of the transmitter is indicated by a two-color control LED (red/green). This
is lit green during operation without malfunctions. If a malfunction such as a probe break occurs
then the signal starts flashing.
