Описание:
From our range of rugged portable pressure calibrators designed for applications from 0.2 bar up to 600 bar, the 7018 differential calibrator covers DP from 0.2 bar to 10 bar in four ranges - specify when ordering the DP and static line pressures, The optional 7090 Pneumatic hand pump can be used as a pressure source covering the range -950 mbar to 40 bar, see separate datasheet.
Also available is a single channel pressure calibrator the 7010, complemented by a dual channel version; the 7015, see separate data sheets. Alternatively, when external line pressures are available the 7010 can be supplied with an internal regulator to control the output pressure - see separate 7016 LPR datasheet.
For process signal calibration the loop signal is displayed on the LCD display to 0.05% accuracy. Loop drive supply (24V or 36V) is also provided. Both pressure and loop signal can be displayed at the same time to speed up the calibration of pressure transmitters. Additionally a continuity function is available for testing for open circuit loops.
The 7018 allows switch selection of four pressure units. These should be specified on ordering from the following:- bar, PSI, kPa, cmWg, inHg, mmHg, Kg/cm2.
Both pressure and loop current are displayed on a 4.5 digit LCD switchable back lit display.
RS232 connection for display read-back when used with Time Electronics EasyCal calibration software (option). Straightforward calibration procedures are easy for the user to write within EasyCal. Results from procedures are stored in EasyCal’s results database and printing calibration certificates on demand is simple.
Power is via internal rechargeable cells with a built in mains charger. This allows the unit to be powered directly from the mains if required. The 7018 is housed in a strong resin case that provides on-site protection. All pressure connections are inside the case mounted on the top panel. Leads and an assortment of pressure connection accessories are provided.
For process control signal simulation Time Electronics’ handheld 7006 Loop-Mate is available as an option. It provides 4 - 20mA and 0 - 10V signals at levels of 0%, 10%, 25%, 50%, 75%, 90%, 100%. It can also step through these set points automatically to allow hands free calibration. It is battery powered and can be stored in the 7018’s pouch. Please see separate datasheet for more information.
