A “best fit” for your process calibration requirements

“Doing more with less” is a requirement every process manufacturer faces today. To maintain product quality, reduce waste, improve efficiency and conform to regulatory standards, instruments that measure process variables such as temperature and pressure must be calibrated at regular intervals. Selecting the right calibrator for the job, however, can be tricky—especially when attempting to balance precision and versatility with cost. Less expensive than high-end multi-product calibrators, yet more precise and versatile than handheld field calibrators, the 7526A is a “best fit” for instrument shops that value precision, versatility and economy.

Intuitive user interface

The user interface includes cursor controls, function keys and a ten-key keypad, making it easy to navigate through intuitive menus; store and recall up to nine setpoints for each input/output parameter; enter RTD or SPRT coefficients; and easily change display units with a key press. With two LCD displays, you can easily view both source and measurement results simultaneously.

Increase efficiency through automation

For increased efficiency and calibration throughput, or to operate an automated test system (ATE), combine the 7526A with MET/CAL® Plus Calibration Management Software. MET/CAL Plus is a powerful application for creating, editing and testing calibration procedures and collecting and reporting results on a wide variety of instruments. It includes MET/CAL® software– the industry leading software for automated calibration, and MET/TEAM™ Express–a dedicated system to manage your test and measurement assets. Or choose MET/TEAM™ standard edition for fully-featured enterprise calibration asset management, with optional modules for on-site calibration, commerce management, and customer web portal. The 7526A standard computer interface includes RS-232 and GPIB (IEEE-488). A USB-to-serial adapter cable is also included with the calibrator as standard.

Don’t forget the sensor

Calibrating the electronics portion of a temperature transmitter is only a part of a complete calibration. You also need to calibrate the temperature sensor itself, whether an RTD or thermocouple. Ignoring the sensor can be a mistake, because temperature sensors are responsible for more than 75% of the output errors in temperature transmitters. You can calibrate the temperature sensor individually, or calibrate both the sensor and the transmitter as a system using a dry-block calibrator such as the Fluke Calibration 914X Series Field Metrology Wells. The Field Metrology Wells were designed specifically with process calibration in mind—optimizing speed to temperature, portability, stability and accuracy. The 7526A and a 914X dry-block calibrator make a perfect combination for calibrating just about any temperature transmitter.

Source as well as measure pressure

The P5500 series of comparison test pumps can be used with the 7526A and Fluke 700 series pressure modules to generate or control test pressures. The unique test port configuration allows for easy, tool-free connections of a wide variety of connection sizes and types, including NPT, BSP, and metric threads. The P5510 includes a built-in hand pump to generate vacuum or positive pressure up to 300 psi (2 MPa). The P5513 allows for precise control of pneumatic pressures up to 3000 psi (20 MPa). An external pressure supply is required. The P5514 allows for generation of hydraulic pressures up to 10 000 psi (70 MPa). The P5515 includes a built-in priming pump and screw pump that allows for pressure generation up to 20 000 psi (140 MPa). Both the P5514 and P5515 can be used with oil or water. Special versions are available with ethylene propylene seals for use with more aggressive fluids.
