Handy Calibrators
CA12E Temperature Calibrator
Source/measurement of 10 kinds of thermocouples
Features
Simulator of Common Thermocouples and RTD Sensors
Outputs a signal equivalent to signals of ten types of thermocouple K, E, J, T,
N, S, B, L, M and R as well as Pt100 resistance temperature detector.
Suitable for a broad range of applications such as maintenance of industrial
process instruments and various thermometers.
Multi-range Thermometer
Can be used as a multi-range thermometer. Three-wire RTD connection for an
RTD is possible.
Built-in Sensor for Reference
Junction Compensation
Reference junction compensation when generating a thermocouple signal can
be performed by the built-in temperature sensor. For more precise compensation,
use the external RJC sensor (model B9108WA, sold separately).
Shift Key
Selects “temperature” or “RTD” unit.
Terminal Adapter
Provides screw terminals for connecting a temperature sensor such as a
thermocouple and RTD when measuring temperature. When generating an RTD
signal, a three-wire RTD signal can be output using the lead cables that come
with the CA12E by short-circuiting the Lo-Lo terminals using the short-circuit bar
that also comes with the CA12E.
