Description
The new SEBA Data Logger type MDS Dipper-3(T3) is the consequential further development of the well proven MDS Dipper for continuous registration in ground- and surface water, with special focus to the operation and data security:
A watch-dog-function, integrated in the MDS-Dipper- T3 supervises continuously the microprocessor activities and so it provides a high operation security. Undefined system conditions are recognized immediately and eliminated by the Watch-dog- function.
The MDS Dipper-3(T3) is equipped with a Flash- memory (Flash-RAM). The acquired measuring data are stored in a ring memory organisation. Due to the described double data storage, you have access to the complete measured data in the archive data backup, even in case of breakdown of the power supply!
Further important characteristics of the MDS Dipper-3(T3)
robust housing of anti-corrosive steel with high chemical resistance for installation in tubes from 1" diameter
exchangeable lithium batteries for >10 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.) and temperature sensor for 0...25°C or 0...50°C
with diameter independent fixing device, suitable for all standard top pieces
So the new MDS Dipper-T3 sets standards in regards to operation security, data security and functionality!
Data transfer to PC
water level sensor,water temperature sensor
Integrated robust, high accuracy pressure and temperature transducer with excellent long-term stability.
Operation with handterminal HDA or notebook PC
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 WBedien CE for simple programming, adjustment and operation of SEBA Data Loggers (i.e. MDS-Dipper), 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, the data logger MDS Dipper-T3 can be connected directly to a PC (i.e. Notebook) or to a data transmission modem, due to serial interface.
Evaluation of measured values with PC
For the evaluation of data, programmed routines are available - and so easy operation is guaranteed.
