Yokogawa CA320 Thermocouple Process Calibrator

The Yokogawa CA320 is a dedicated process calibrator which is capable in performing inspections and calibrations of thermocouples. It has an accuracy of ±0.5℃ error and is able to source thermocouple output and measure output of sensors.

It not only corresponds to JIS standard and IEC standard thermocouples, but corresponds to ASTM standard and GOST-R standard too. It corresponds to inspection and calibration with the summary of 16 types of thermocouples following the standards.

Key features

  • Easy-to-use, high-accuracy temperature calibrator
  • Thermocouple Calibrator (16 types of thermocouples)
  • Corresponds to various types of source pattern (Step sweep/ Linear sweep/ Manual step/ Span check)
  • Measures TC sensor output as a thermometer

Yokogawa CA320 is a Thermocouple Calibrator

The Yokogawa CA320 is a Thermocouple calibrator and is a high accuracy source and measure portable handheld calibrator. It is 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.

It provides an ergonomic and friendly user-interface making it easy to use. The Yokogawa CA320 thermocouple Simulate model corresponds to 16 types of TC for sourcing. It achieves the high basic accuracy of 0.5°C (typical of type K), three times better than the previous model which enables it to operate a highly reliable test.

Additionally, the difference of temperature between objects can be compensated, by using external RJ sensor or a compensating lead wire. The Yokogawa CA320 can measure the output of TC like a thermometer.

Yokogawa CA320 Features:

  • Corresponds to 16 types of TC standard (JIS/IEC/DIN/ASTM/GOST R)
  • Sub display displays value of voltage source and span%
  • Various types of source pattern such as step sweep/ linear sweep/ manual step/ span check
  • Corresponds to other TC types by mV source function
  • 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
