Multifunctional calibrator ElMetro-Pascal-03
Portable multifunctional calibrator ELMETRO-Pascal-03 is designed for accurate reproduction and measurement of overpressure and absolute pressure / vacuum, electrical voltage and DC current signals, as well as power supply of sensors and communication with smart sensors using the HART protocol.
The archiving function and the interface with the PC make it possible to form a verification protocol. The function of generating and simulating the output current signal of the sensor allows you to monitor the state and error of the communication channels of secondary devices and controllers.
In terms of their metrological characteristics, the calibrators comply with the requirements for the 1-st category standards in accordance with GOST 8.022-91 in the mode of measuring and reproducing the DC current, for the working standards of the 3rd category in accordance with GOST 8.027-2001 in the mode for measuring the DC voltage, for the working standards of the 1st or 2nd category in accordance with GOST R 8.802-2012 when measuring excess pressure / vacuum with external pressure transducers, to working standards of the 2nd or 3rd category in accordance with GOST R 8.840-2013 when measuring absolute pressure with external pressure transducers.
The ELMETRO-Pascal-03 pressure calibrator consists of the following main units:
- electronic unit;
- source of creation and precise regulation of pressure / vacuum;
- external reference pressure modules.
A calibrator without a pressure transducer is functionally a current loop calibrator.
Functionality.
Calibrators are manufactured in general industrial and explosion-proof design. Explosion-proof calibrators are marked with explosion protection 1ExiaIIBT4 X.
The electronic block of the calibrator has a built-in 24 V power supply, which makes it possible to work in the "field" without a power supply unit.
Any pressure measuring instruments included in the State Register of SI RF and having an interface compatible with the calibrator (including ELMETRO-Pascal-04, Metran-518) can be used as external transducers.
