Rugged
portable pressure calibrators designed for applications from
0.2 bar up to 600 bar in eleven ranges - specify when ordering.
For the 7015, the pressure source is via external hand pumps.
Pneumatic: -0.85 to 35 bar, or Hydraulic: 0 - 250 bar. Also
available a single channel version (see separate 7010 Single
Channel datasheet). Alternatively, when external line pressures
are available the 7015 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
7015 dual channel version allows switch selection of five pressure
units on channel one and four pressure units on channel two.
These should be specified on ordering from the following:- bar,
PSI, kPa, MPa, inWg, cmWg, inHg, mmHg, Kg/cm2, atm. Both pressure
and loop current are displayed on 4.5 digit LCD displays.
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 7015 is housed in a strong resin case
that provides on-site protection. All pressure connections are
on the side of the case. 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 7015’s pouch. Please see separate datasheet
for more information.
