Measuring technology
Measuring technology
Sensors for permanent use in concrete
MRE
Sensor consisting of 8 stainless steel rings insulated from each other, for determining depth-dependent moisture profiles.
Anode ladder
System consisting of several individual sensors (rungs), which are installed between the concrete surface and the reinforcement in order to continuously monitor the advance of the depassivation front.
Supplementary cathodes
Pt 1000
Temperature sensor with 1000 Ohm resistance at 0°C.
Sensors for structural diagnostic investigations
Wenner probe
Sensor for non-destructive measurement of the specific electrical resistance of concrete.
Hand-held measuring devices
HMG6, ALMT
Hand measuring device 6; Anode ladder-Measurement technic; Measuring instrument which is used in combination with anode conductors or MRE to monitor the progress of corrosion. The HMG 6 can also be used stationary as a data logger.
WS-HMG1
Wenner probe handheld meter.
HMG-MUX
Handheld measuring device Multiplexer, which offers the possibility to connect and control different sensors at the same time.
Stationary measuring chains
MRSE
Multiring-Sensorelektronic; Measuring method for determining resistance by measuring currents at a given sinusoidal voltage (108Hz, 2Vpp, measurement against cathode).
UIME
Voltage-current measuring electronics (voltage: +/- 2V, current: 2mA - 200mA).
MIG 9K
Voltage distributor and measuring device for current and voltage measurement of the RCM experiment (Rapid Chloride Migration). RCM: Experiment to determine the chloride migration coefficient.
TME 2 / Pt1000
Measurement of currents at a given voltage to determine resistance or temperature.
PC-Opto-Schniwa
Interface converter whose power supply is ensured by the PC.
Datalogger USB
Datalogger in which the data is stored locally on a USB stick.
BDL1
Data from the measurement technology is read out and stored on a USB stick with its own power supply (battery).
Ethernet-Schniwa
Ethernet interface converter to which access via network is possible.
GPRS-Logger
Data logger in which the data is read out via the mobile phone network.
GSM-Logger3
Data logger where the data is read out via the internet, e.g. daily sending of data via e-mail.
Software
Data transfer
Software by means of which the daily log files generated by the respective measuring devices or data loggers can be read out and stored locally.
Acquisition software
Software by means of which the daily log files generated by the respective measuring devices or data loggers can be summarised for further processing.
EXCEL data import
Plugin for Microsoft EXCEL to facilitate the import of the summarised log files for further processing and evaluation.
