Electric Pressure Calibrator


Fluke Corporation has announced the new Fluke 719 Electric Pressure Calibrators. These high performance, lightweight devices feature a built-in electric pressure pump that makes it possible to quickly calibrate and test pressure devices with one hand. Process technicians, plant maintenance technicians and instrument technicians who do pressure calibration work often use manual pumps to pressurize transmitters and gauges. That requires the use of two hands: one to pump and one to hold the pressure calibrator. With its built-in, battery powered pump controlled by a thumb button, the Fluke 719 pressure calibrator is more convenient, faster and easier to use. The electric pump can be programmed to set target pressures or limit pressure to eliminate over pressurization. It is designed to perform 5,000 pump cycles between rebuilds. Its unique cleanout port makes it easier to service the Fluke pressure calibrator without sending it out for repair. The cleanout port minimizes pump failures caused by accidental exposure to contaminating fluids. Much smaller than other electric pump portable field calibrators, the Fluke 719 weighs 2.19 pounds (992 grams) and operates on two 9 V alkaline batteries. Its ergonomic design was based on input from users and thoroughly field tested. Precision measurement features of the Fluke 719 pressure calibrator are best-in-class with pressure measurement uncertainty of 0.025 %. The device will measure and source mA with 0.015 % accuracy. It can simultaneously measure pressure and source mA to test valves and I/Ps. The Fluke 719 can also simulate mA signals to troubleshoot 4-20 mA control loops. Two models are available: the Fluke 719 30G, with a pressure range of -12 psi to 30 psi (-850 mbar to 2 bar), and the Fluke 719 100G, with a range of -12 psi to 100 psi (-850 mbar to 7 bar).
