Sendyne Signature Series -- Extreme Precision Current and Voltage Measurement Modules
Sendyne Signature Series Lab Grade Current and Voltage Measurement

The Sendyne Signature Series are lightweight, portable current, voltage and temperature sensing modules suitable for precise laboratory measurements. Individually calibrated, these modules precisely measure current over a wide dynamic range with an accuracy of 0.05%. Galvanically isolated, the module incorporates a 100 µOhm shunt that allows measurement of currents up to ± 100 A continuous (± 500 A peak). Alternate shunts are available for those who wish to measure smaller or higher currents.

Applications

  • High accuracy lab environments
  • Current flow precision metering 
  • Battery monitoring for industrial, automotive, railroad and utility scale storage

  • Achieves ±0.05 % accuracy of current measurement over temperature range of –40 °C to +125 °C
  • Accurate voltage measurement (±0.05 % typ.) with flexible range 
  • Time between measurements is 5 milliseconds 
  • Measures mA to 500 A; LAB-25 measures mA to 1500 A 
  • 61 µA resolution 
  • External temperature can be measured with ± 1 °C precision 
  • Separate Charge, Discharge, and Total Coulomb counters
  • Simple serial communication interface 
  • Software library available on GitHub for interfacing to NI's LabView and other programs
  • Low power consumption  
  • Isolated front end for “high” or “low” side current sensing and attenuation of system-induced noise
  • Description

    The Sendyne SFP101LAB and SFP101LAB-25 are lightweight, portable current, voltage and temperature sensing modules suitable for precise laboratory measurements. The individually calibrated Sendyne Signature Series modules precisely measure current over a wide dynamic range with an accuracy of 0.05%. Galvanically isolated, the module incorporates a 100 µOhm shunt that allows measurement of currents up to ± 100 A continuous (± 500 A peak). Alternate shunts are available for those who wish to measure smaller or higher currents. Due to Sendyne’s proprietary temperature compensation feature, this 0.05% accuracy is maintained from –40 °C to +125 °C. Time between measurements is 5 milliseconds, making the unit practical for real time experiments. Resolution is 61 µA. A voltage channel is capable of measuring voltage with nominal full scale voltage of ±150 V. An external temperature can be measured with ± 1 °C precision. The modules also offer built-in precision Coulomb counting (charge accumulation), with separate counters for charge, discharge and total Coulombs.

    For laboratories utilizing National Instruments LabView or other software, Sendyne provides a software library which can be freely accessed from GitHub. This enables multiple units to measure various currents simultaneously. A video providing implementation instructions for porting the library into LabView is available from Sendyne’s YouTube channel. Comprehensive technical support is also provided. In addition, Sendyne offers free, PC-based testing software, downloadable from the company’s website.

    The standard module communicates to a host over a simple serial protocol; a serial to USB cable enables interface to a PC. Other protocols are available. Other modules are available for laboratories needing to measure multiple / higher voltages.

    Sendyne offers yearly unit recalibration for a nominal fee as well as a swapping program. Signature series modules are $499 in single unit quantities.
