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.
