Time Electronics 7010

 
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.

The 7010 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.
