INMEL 8033 Calibrator is a three-phase electric power and energy calibrator. It generates voltages of equal rms value on three voltage outputs and currents of equal rms value on three current outputs. The voltage on voltage output and the current on current output are shifted between them by set phase angle. Against to the previous model calibrator type INMEL 33, the new device INMEL 8033 one characterize less voltage, current, power and angle generation error, has also wider frequency range of quantity generate and richer program function set. The most important from program functions is the possibility to generate harmonic course. The main distinctive feature of INMEL 33 from INMEL 8033 is digital method measurement generating and stabilization output signals. Application: Checking ang calibration: - Wattmeters, varmeters, - phase meters, - frequency meters, - AC of voltmeters and ammeters, - power factor and phase angle meters, - measuring transducers, - watt-hour meters in single and three-phase system, - power engineering protections.
Parameters: - simulation and measurement: thermocouple signals J, K, T, R, S, B, U, L, E, N, with auto-compensation of terminal temperature, signals in thermocouple and thermostat system, resistance thermometer signals: Pt 100, Pt 500, Pt 1000, Ni 100, Cu 100, resistance signals from 10 up to 5 , voltages and currents in range: -11 V...+11 V and 22 mA...+ 22 mA - accuracy 0.025% - STEP and RAMP function, - led out 24 V terminals, - RS 232C interface, - available in the option for pressure calibration. The INMEL 60 calibrator is destined to check and control systems, industrial automatic control engineering devices such controllers, recorders, meters, etc. This instrument has the possibility to generate and measure signals from ten thermocouples, five thermometer resistances, four voltage ranges, two current ranges, two resistance ranges. Thermoelectric terminals have an internal temperature measurement and for this reason make possible the generation or measurement of thermoelectric signals with the compensation for the given thermocouple. In this working mode, a real thermocouple is added to thermoelectric measuring terminals, and compensation conductors to thermoelectric generating terminals. The calibrator ensures the simultaneous generation of the signal on output terminals and the measurement of the signal on measuring terminals, thanks to this feature the calibrator is suitable to check transducers. The INMEL 60 calibrator enables to check two-wire transducers. the used graphical display contains a lot of information on a screen with a good readability. The display ground-lighting, which can be switched off, is especially useful in conditions of an insufficient lighting. The internal supply from the battery enables the work not only in laboratory conditions but also on the object. The calibrator can also be used to the maintenance and servicing of industrial measuring instruments, systems and electronic equipment. Application: Checking and calibration: - measuring transducers controlled by a voltage or current signal, a thermoelement or resistance thermometer, - two-wire transducers, - temperature meters, - pressure transducers, - manometers, - measuring and control lines.
