HBMD-PH and HBMD-L
Introduction and Design
HBMD-PH and HBMD-L are similar products with
different software settings.
HBMD-PH work together with the pH sensor
HBPH mk2 and is designed to display the pH level
directly. The calibration is done in the display box
and a linear pH output is passed on 4mA for pH
=0 and 20 mA for PH=14.
HBMD-L work together with any 4-20 mA analog
output for example a level sensor and provide a
0-100% display the same as shown on a level
sensor. The display can be placed where you
need it connected in between the sensor and the
PLC using M12 connectors.
The M12 plug at the end of the black box is the
sensor input and the plug on the blue surface is
the plug connected to the PLC.
Power supply is made via the M12 connector
The display will be 3 digits 0-100 when working
as level sensor and be 2 digits including 1
decimal when showing pH value
