Q.bloxx A105 CR Cryo Module with Extended Range

Our advanced 4-channel Q.bloxx A105 measurement module sets new standards in terms of stability and precision. For many different applications, the extremely precise and stable measurement of temperatures is an absolute prerequisite for the control of processes or the success of product innovations. In addition to the essential precision, particularly important aspects of this are the maintenance of stability when changes occur in the ambient temperature and ensuring long-term stability.

A clear trend is that these cryogenic temperature sensors move to higher resistance. With Gantner’s cryo module – the Q.bloxx A105 CR – a measurement range of up to 25kohms is now possible. The module is available as standard DIN rail module, or as Q.brixx/Q.raxx with 4 times 4-pole-LEMO (ERA.1S.304.CLL).

Key Features:

• 4 galvanic isolated input channels for cryogenic sensors
  e.g. Type Cernox, Type TVO
  input range selectable 6500 Ω and 20000 Ω
• Sensor excitation 7.5 µAeff only
  avoids self-heading of the sensor
• Individual linearization of the sensor characteristics
  Sensor specific linearization by using 32 nodes and archive in a sensor data file. Import of manufacturers calibration data
• High accuracy digitalization
  24 bit ADC, 10 Hz sample rate per channel
