Temperature Measurement PT100 in
3-Wire Connection
The Pt100 sensor in a 3-wire connection is rarely used but can be
configured with Lizard Setup Software like any other sensor.
In the Equipment view, select the predefined Pt100 sensor from the
list. Proceed then to the Measurements view and select a Pt100
measurement. In order to change to a 3-wire measurement, change the
user level to Advanced. The first parameter indicates whether the
measurement in question is a 3- wire or a 4-wire one. You do not need
to change any other parameter default values.
Absolute Shaft Encoder
Absolute Shaft Encoder measures water level in a stilling well. It is
based on a true absolute shaft encoder that uses SSI (Synchronous-
Serial Interface) for communication. The QML logger is connected to
the encoder via the QMI102 adapter module that reads data from the
encoder and sends it as ASCII via the RS-232 or RS-485 line. QMI102
may be connected to COM1 or any other communication port that
supports either RS-232 or RS-485. The QMI102 module is installed
inside the enclosure.
