Model M631 is high accuracy RTD simulator with range from 16 Ω to 400 kΩ. Basic accuracy is 0.01°C, resolution is 0.001°C.
Decade consists of highly stable foil resistors switched with combination of relays.
Apart from RTD temperature sensor simulation (temperature setting in degree of Celsius or Fahrenheit)
the M631 can be also used as a standard resistance decade.
Instrument can be controlled via RS232, USB, LAN or GPIB interface. Decade uses internal power supply with very low noise level.
Simulator can be used also for AC application. Typical frequency response is in the datasheet.
RTD simulator is designed for calibration laboratories for tempertature testing of RTD evaluation units
like temperature regulators, transducers, etc.
Having resistance simulation function, M631 can be also used as ohmmeter calibrator or as device for
quality testing in industry as well.
Simulator can be ordered as 19" module for easy assembling into a 19" rack. Module height is 3HE.
