Description
The new SEBA Data Logger type MDS Dipper- TEC is the consistant further development of the well proven MDS Dipper Series for the continuous monitoring of ground- and surface water, with special focus to operation and data security.
An integrated watch-dog-function in the MDS-Dipper-TEC continuously supervises the microprocessor activities and therefore can guarantee a high operation security.
The MDS Dipper-TEC is equipped with a Flash- memory (Flash-RAM). The recorded monitoring data is stored in the memory of the Dipper-TEC where the data is always recallable even in the unlikely event of a power supply failure.
Additional important characteristics of the MDS Dipper-TEC:
robust housing of anti-corrosive steel with high chemical resistance for the installation in well casings starting from 2" in diameter
exchangeable lithium batteries for >8 years operation (depending on the adjusted measuring interval)
high accurate, robust ceramic pressure measuring cell for different measuring ranges (i.e. 1 bar, 2 bar, etc.)
diameter independent fixing device, suitable for all standard top pieces
The new MDS Dipper-TEC sets new standards in regards to operation and data-security, as well as functionality!
Data Transfer to PC
Water Level Sensor/Temperature Sensor/Conductivity Sensor
Integrated robust, high accuracy pressure and temperature transducer with excellent long-term stability as well as conductivity sensor with 4 electrode technique.
Operation with HDA or Notebook
Robust HDA for the rough field operation as alternative to a notebook. Vibration, impact, dust and water resistant housing according to IP67 for operation between -30°C up to +60°C.
Long durability up to 30 hours.
Simple operation resp. input of parameters (i.e. of control values) via TFT-colour-LCD-touchscreen or pin.
Included in the delivery:
Operation software SEBAConfig for simple programming, adjustment and operation of SEBA Data Loggers (e.g Dipper-3), as well as for transmission of the stored measuring values to PC.
Evaluation software MGMDS/MLMDS CE for plausibility check of stored measuring data in form of curves and lists.
Of course, your data logger can directly be connected to a PC (e.g. Notebook) or to a data transmission modem, thanks to its serial interface.
Evaluation with PC
For the data evaluation, pre-programmed routines are available for the client - which guarantee an easy operation.
