The 7018 is a fully integrated differential pressure test and calibration system. It is suitable for field and laboratory calibration work of both diffential pressure and electrical process loop signals. The instrument is available in pressure or vacuum configuration, with the range specified on ordering. Standard available versions are; Vacuum 0.2, 2, 5, or 10bar. Static line pressures must also be specified. Best accuracy is 0.04% of range and maximum display resolution is 0.005% of range. The excellent resolution allows higher accuracies to be achieved under controlled lab conditions when accurate pressure standards such as dead-weight pressure testers are available for transfer calibration. 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 7018 allows switch selection of five pressure units. These must 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 a 4.5 digit LCD display. Options For the 7018, input pressure can be generated by the 7090 pneumatic hand pump (-950mbar to 40bar). Accompanying 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 7018’s supplied carry pouch. The 7018 is fitted with RS232 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. Portable Operation 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 7018 is housed in an impact resistant safety case that provides protection and increased durability for field use. All pressure connections are on the side of the case. The unit is supplied with a pressure hose, electrical test lead, 2 electrical probes and 2 crocodile clips.
