MIDS-20X mutual inductance detection system

  • dedicated, ultra-low noise mutual inductance detection system for measuring the SRD1000 and CMN1000 sensors;
  • design ensures minimal rf-heating of ultra-low temperature experiments;
  • (remotely) adjustable preamplifiers are positioned close to cryostat, the control unit is near the user for optimal signal performance and ease of use; 
  • 'plug and play': sensors and electronics are matched, no adjustments are required to measure the full range 10 mK  to 10 K;
  • primary currents sensors: 50 or 125 µA @ 976.5 Hz;
  • DC system output voltage: 0 - 2 V, proportional to the sensor signal level;
  • two 24-bit ADC's with optical USB interface (galvanically isolated from the system) to sample the output signals;  
  • system comes with software tools (DLL interface and LabVIEW VI) for data acquisition and processing;
  • overall temperature coefficient of the electronics is better than 50 ppm/°C;
  • the MIDS-202 is a 2-channel detection system for simultaneous measurement of an SRD1000 and CMN1000 sensor;
  • the MIDS-201 is a 1-channel version of the MIDS-202, an optional multiplexer unit (SSB-01) allows switching between 2 measurement channels.
