RESISTOMAT® 2329
The RESISTOMAT® model 2329 is particularly suitable for fast measurements of low resistances in automated processes. Up to 50 measurements per second can easily be performed. The device complies with the latest CE guidelines and is designed for laboratory use as well as heavy-duty industrial applications.
A 2-fold and 4-fold comparator with switching outputs has been included for classifi cation and selection; this feature is particularly useful for serial tests.
One special application involves the measurement of contact resistances (dry-circuit measurement); the load voltage in this case is limited to 20 mV in order to prevent fritting (DIN IEC 512). The RS232 (standard) and IEEE488, USB and Ethernet (option) computer interfaces allow the set-up of fully automatic testing stations. The PLC interface allows easy integration into your production process control.
Typical applications are resistance and conductivity measurements on:
Fuses
Airbag triggers
Coils for the automobile industry and electrical engineering
Plug-in contacts and switches
Commutator welded joints
Meter samples in cable manufacture
Circuit-board conductors etc.
The device operates on the basis of proven 4-wire technology which corrects any incoming line or contact resistances.
The measurement lines are checked by an integrated cable rupture monitor. Needless to say, the functions include temperature compensation for various test substances such as copper, brass, tungsten etc. Temperatures are measured by a Pt 100 sensor or infrared sensor (pyrometer) with analog outputs or any temperature transmitter e.g. thermocouple.
