Description
The compact microprocessor operated transmitter /controller
measures and controls the pH value in aqueous solutions. It
is available as a panel-mounted device according to DIN
43 700 or in a IP 65 field housing.
Its simple operation and user-friendly programming allow universal
service in almost all areas of industrial applications.
The transmitter is fitted with two analogue and two binary
inputs. The first analogue input is suitable for connecting a
pH combined electrode. A Pt 100 resistance thermometer
can be connected to the second analogue input.
The device has two 4-digit, 7-segment displays for indicating
pH value (red) and temperature (green).
The displays show comments during programming, to facilitate
the operation.
The two control relays can be configured as limit value
and/or pulse lengths or pulse frequency controllers with P, PI,
PD or PID structure. A maximum of two relay contacts, one
binary output and one analogue output is available.
To simplify programming and operation, the controller parameters
and configuration data have been assigned in different
levels.
● Operating level
● Parameter level
● Configuration level
The levels are secured with pass words against unauthorized
access. Membrane keys ensure simple and user-friendly
operation.
Both LEDs show parameter symbols and values.
The device can be switched from pH to ORP measurement.
