The precision RTD simulator is used where measuring instruments or controlling means with high precision must be examined or calibrated. The simulator is suitable for calibration laboratory and service centers which need a computer-controlled resistance decade for the automation of calibration procedures.

All standard platinum and nickel RTD can be simulated with very high accuracy according to scales ITS 90 or IPTS 68.

Temperature regulators, transducers etc. often supply a pulsed signal current in order to reduce the self-heating of the RTD. Devices with electronic simulation of RTD are therefore inclined to swinging and do not function with this application. Here, the advantage of the RTD simulator model 4530 becomes obvious as it can simulate the resistance sensor by real Ohm simulation without problems.

Of course the RTD simulator can be used also as classical resistance decade.

The equipment comes in a sturdy aluminium housing. The keyboard and display are on the front plate. It makes 2-, 3- and 4-wire connection possible at the back side.
