Description

The 7040 is a portable pressure and current calibrator suitable for workshop, laboratory

and field use. With the capability to measure both loop current and pressure, devices

such as transmitters and converters to be calibrated directly. Basic accuracy is 0.04 %

of full scale (0.025 % optional). Pressure can be displayed in any of nine popular

engineering units; Bar, PSI, KPa, inWg, cmWg, inHg, mmHg, Kg/cm2, and Atm.

Loop current can be displayed in mA, or as a percentage of span (4 - 20 mA).

A min/max logging function (pressure or loop current) is provided. The min or max

values can be recalled to the display and if required can be viewed in real time.

An additional feature is leak rate display. This allows the actual leakage rate to be

observed in real time in the selected ‘pressure units’ per sec, or per min.

By connecting the 7040 to a PC or laptop via RS-232 and using a suitable program (see

EasyCal details below) the displayed parameters can be read back: Pressure, Loop

Current, Max Value, Min Value. By arranging for the program to store these values in a

database a full data logging set-up is possible. The display is 4.5 digit LCD and power

is via a 9 V PP3 battery. The 7040 is supplied with pneumatic fittings kit and hose, test

leads, technical manual, RS-232 lead, and carry case.

Options

For the 7040, input pressure can be generated by the 7090 pneumatic hand pump

(vacuum to 40 bar). The 7090 is compact with comfortable handles with grips moulded

into the design make it easy to control the instrument whilst pumping up to pressure.

Features include protective caging for the vent valve guarding against accidental

damage, and dual o-rings on all pistons to ensure zero leakage. Also available are a

range of pumps suitable for workshop use, that feature an ergonomic mode of

operation. These models include the the 7193 (vacuum to 40 bar pneumatic) and 7192

(vacuum to 25 bar pneumatic).

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 7040 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.
