The CS series precision shunts are designed for highly accurate measurements of current.

The CS shunts feature good long term stability and a low temperature coefficient of resistance. Although designed for laboratory use, they are rugged enough to be installed in environments subject to wide variations in temperature and to vibration or shock.

The CS shunts are of bifilar construction, with low reactance. They may be used with practically no degradation in accuracy at 50/60 Hz, and with close conformance at higher frequencies.

The temperature coefficient of resistance is less than 5 ppm / °C (CS-100 & CS-200); the CS-300 is less than 20 ppm / °C.

Connection is made via solid copper posts. Internal construction eliminates connection errors common to many other shunts.

Every shunt includes ISO 17025 accredited, NIST traceable calibration at 25, 50, 75 & 100 % of rated current. Customer specified measurement points can be provided on request.

Standard CS models are listed; other Amp/Volt combinations are available on request.

For the highest precision applications, a 100 ohm RTD 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. Type T or thermistor sensors are also available.

* Accuracy includes full current range, 18-30 °C, 12 month
