Yokogawa CA330 RTD Process Calibrator


The Yokogawa CA330 RTD simulate model corresponds to 14 types of RTD for sourcing. It achieves the high basic accuracy of 0.3°C (typical of type PT100), twice better than the previous model which enables it to operate a high reliable test. CA330 can measure the output of RTD like a thermometer.

  • Corresponds to 14 types of RTD standard (JIS/IEC/GOST R)
  • Sub display displays value of resistance source and span%
  • Various types of source pattern such as step sweep/ linear sweep/ manual step/ span check
  • Corresponds to 2, 3, 4 wire & realizes RTD simulation
  • Operating temperature range from -10°C to 55°C
  • Dimension is 90mm (W) x 192mm (H) x 42mm (D)
  • EN61010-1 / EN61010-2-030 safety standard
  • Segment LCD display and LED backlight

The Yokogawa CA330 is a high RTD portable handheld calibrator used to inspect and maintain the accuracy of control devices such as temperature controllers, temperature transmitters, temperature sensors and other process devices which are used in process plants, industry machinery, and manufacturing.

The Yokogawa CA330 is a dedicated process calibrator which is capable of performing inspections and calibrations of RTDs. With a high accuracy of ±0.3℃ which is top class as a handy type to source resistance output and measure output of sensors. It not only corresponds to JIS standard and IEC standard thermocouples, but corresponds to GOST-R standard also. It corresponds to inspection and calibration with the summary of 14 types of RTD following the standards.
