Shunt de courant de métrologie de 500 à 1000A
- Détails
- Catégorie : Shunts de courant de métrologie
Shunt de précision - 500 à 1000 AMPS
- RATED FOR CONTINUOUS FULL CURRENT
- FOR CALIBRATION USE
- GOOD LONG TERM STABILITY
- HIGH ACCURACY
The CS-500 and CS-1000 Shunts are designed for precise measurement of higher currents. A recent design upgrade has improved the accuracy of these shunts.
The CS-series shunts are rated for full continuous current with no loss of accuracy. Heat generated by the measurement current is adequately dissipated by the surface area of the exposed elements.
The CS-500 and CS-1000 are open, parallel blade construction. They have been found to agree well between DC and 50/60 cycles, but are not recommended for pulse or high frequency use.
For lower currents, please see our CS-1 through CS-300 shunts, or the MCS Multiple Current Shunt, a temperature-stabilized shunt instrument covering the range from <10 mA to 300 A.
All shunts are supplied with ISO 17025 accredited, NIST traceable calibration through full rated current.
For the highest precision applications, a temperature sensor can be bonded to the shunt element, and full current / temperature characterization can be provided. Please see the Temperature Option for an example of this characterization. 100 ohm RTD, type T thermocouple and 10 K thermistor sensors are available.
