7040 Digital Pressure/Current Calibrator

The 7040 is a portable pressure calibrator suitable for workshop, laboratory and field use. With the capability to measure process loop current and pressure, devices such as transmitters and converters to be calibrated directly. Basic accuracy is 0.04 %. 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 to 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.

The display is 4.5 digit LCD and power is via a 9V PP3 battery. The 7040 is supplied with pneumatic fittings kit and hose, test leads, technical manual, RS-232 lead, and carry case. Options are available to generate pressure to the 7040, including the 7090 pneumatic hand pump. Fittings kits like the 7198 are also available. The calibrator is EasyCal software compatible for readback of parameters, enabling automated calibrations to be performed and certificates created.
