DESCRIPTION
The 7010 is a robust portable pressure calibrator that is suitable for field and laboratory calibration work of
both pressure and electrical process loop signals. It is a simple operation instrument ideal for calibrating
and cross-checking pressure gauges, sensors, transmitters, transducers, indicators, switches, and many
other devices. The following versions are available; 0.2, vacuum to 2, 5, 10, 20, 35, 70, 100, 200, 400, or
600bar. Vacuum down to -850mbar is possible on the 2bar version.
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 7010 allows switch selection of four pressure units in addition to mA. Common pressure units are
configured as standard (see specifications), but user-specified units can be requested:- bar, PSI, kPa,
MPa, inWg, cmWg, inHg, mmHg, Kg/cm2, atm. Both pressure and loop current are displayed on 4.5 digit
LCD displays.
Power is via internal rechargeable cells (24 hours typical use) with a built-in mains charger. The unit can be
powered directly from the mains if required. The 7010 is housed in an impact resistant safety case that
provides protection and increased durability. All pressure connections are on the side of the case. The
instrument is supplied with a pressure hose, electrical test lead, 2 electrical probes and 2 crocodile clips.
OPTIONS
For the 7010, input pressure can be generated by external hand pumps. The 7090
pneumatic (-950mbar to 40bar), or 7095 hydraulic (0 to 700bar) pumps are ideal for
this purpose. Gauges are also available.
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 7010’s pouch. See separate datasheets for more information.
The 7010 is fitted with RS-232 connection as standard. Display readback can be
performed using EasyCal calibration software. With comprehensive features
EasyCal can simplify and speed up calibration procedures. Easily produce
calibration certificates and reports to international quality standards.
