Description

The 7015 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

ranges are available for each channel; 0.2, vacuum to 2, 5, 10, 20, 35, 70, 100, 200, 400,

or 600 bar. Vacuum down to -850 mbar is possible on the 2 bar range.

For process signal calibration the loop signal is displayed on the LCD display to 0.0 5%

accuracy. Loop drive supply (24 V or 36 V) 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 allows switch selection of five pressure units on channel one and four pressure

units on channel two where mA is also shown. 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 7015 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 2

pressure hoses, electrical test lead, 2 electrical probes and 2 crocodile clips.

Options

For the 7015, input pressure can be generated by external hand pumps. In the field the

7090 pneumatic (vacuum to 40 bar), or 7095 hydraulic (0 to 700 bar) pumps are suitable.

Also available are a range of pumps suitable for workshop use, that feature an ergonomic

mode of operation. These models include the 7193 (vacuum to 40 bar pneumatic) and

7194A (vacuum to 200 bar pneumatic). For hydraulic pressure generation the 7195

pump (vacuum to 700 bar) is ideal for supplementing pressure to the testing applications.

For process control signal simulation a practical tool like the Time Electronics handheld

7006 Loop-Mate is available as an option. It is a low cost, simple operation unit that provides

4 - 20 mA and 0 - 10 V 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 compact, pocket sized and easy to carry in the field.

EasyCal Calibration Software

The 7015 can be controlled with readback via Time Electronics

EasyCal software to automate the calibration process. This

provides increased speed of calibration and consistency of

results. Produce traceable calibration certificates and test

reports for quality standards with additional uncertainty

information for ISO 17025 conformance.
