Description
General information
The portable electric pressure calibrator model SPP70 is a compact, portable pressure calibrator, which has been designed for mobile use as well as for stationary workshop and laboratory testing. An integrated electrical pump enables you to generate pressures from -0.9 vacuum up to 70 bar [1,015 psi] and an integrated electrical module also enables you to supply transmitters or sensors with a current of max. 30 mA (voltage (idling) = DC 24 V), in addition to the traditional measurement of current and voltage signals.
Accuracy
Leveraging on latest Mensor’s technological advantage, the reference sensor offers an accuracy of 0.02 % of full scale. The temperature compensation of the built-in sensor safeguards the accuracy for applications in the field. Readings can be displayed in one of 13 standard units.
Features
With the portable electric pressure calibrator, not only are accurate pressure measurements possible, but also exact current and voltage measurements, as well as a DC 24 V voltage supply for test items are enabled. Pressure values and electrical measured values are simultaneously shown in the display. The calibrator is integrated into a robust, as well as dust and splash-proof transport case. Thus the mobile pressure calibrator is particularly suited to use in harsh industrial environments. The external universal power supply is designed for an operating voltage of AC 100 ... 240 V.
Certified accuracy
For the SPP70, the accuracy is certified by a standard SAC-SINGLAS calibration certificate which accompanies the instrument.
