7018 Differential Pressure Calibrator

The 7018 is a differential pressure calibration system suitable for field and laboratory calibration work of both diffential pressure and electrical process loop signals. The instrument is designed for very stable measurement of differential pressures between its two output ports, enabling the calibration of DP gauges, transducers, and transmitters. There are five available versions, either 0.2, 2, 5, or 10 bar.

Features include a 4.5 digit LCD display with 4 selectable pressure units plus mA, zeroing switch, and two quick release connector ports (Hi and Lo for differential pressure input) that are situated on the front panel of the unit. Best accuracy is 0.04% of full scale.

For process calibration the loop signal is displayed on the LCD display to 0.05% 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.

Portable Pressure Calibrator

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. Pressure connections are on the front panel and the instrument is supplied with a pressure hose, electrical test lead, 2 electrical probes and 2 crocodile clips.

7006 LoopMate

Accompanying Products

For the 7018, input pressure can be generated by external hand pumps. The 7090 and 8090 pneumatic models provide fine output control for testing applications. Gauges are also available.

For process control signal simulation Time Electronics’ handheld 7006 Loop-Mate is available as an option. It 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 can be stored in the 7018’s pouch.

EasyCal Calibration Software

The 7018 has RS-232 communication for use with Time Electronics EasyCal software. This allows users to automate the testing process for 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.
