Measuring, troubleshooting 4-20mA loop signals Keeping manufacturing and processing plants running at maximum efficiency 24-hours a day requires regular inspection and troubleshooting of vital systems and equipment. 4-20mA control loops are the most common control signals used in process industries today. Troubleshooting the mA loop instruments, connections, and cables are an essential part of locating and reparing process control.   Products Showcase 707Ex Loop Calibrator » 725Ex Multi-function Process Calibrator » 87V Ex Intrinsically Safe True RMS Multimeter » Temperature calibrations There are three necessary elements needed to perform a temperature calibration: The ability to source/simulate a temperature signal, power for the transmitter, and the ability to measure the output mA value.   Products Showcase 725Ex Multi-function Process Calibrator »   Pressure calibrations Leaking process lines and/or pneumatic control signals will cause an error in control signals. Use one of our Pressure Calibrators to verify or calibrate pressure instruments are working properly and in proper specifications.   Products Showcase 725Ex Multi-function Process Calibrator »   718Ex Pressure Calibrator »   Ex Pressure models » Switch testing Verify the setpoint and deadband of pressure switches, in classified zones/areas, using a Fluke Ex Process Calibrator.   Products Showcase 725Ex Multi-function Process Calibrator »   718Ex Pressure Calibrator »   Custody Transfer The calibration of process equipment, used during the transfer of a product from one customer to another, is vital to guarantee that product quality and quantity remain accurate.   Products Showcase 707Ex Loop Calibrator » 718Ex Pressure Calibrator »   725Ex Multi-function Process Calibrator »   Troubleshooting process signals Temperature, pressure, flow, and liquid level are the most commonly measured process variables used in industry today. The devices used to measure and transmit this information back to a monitoring station require calibration/verification to specified accuracies. Use one of our Process Calibrators to perform your plants calibrations.   Products Showcase 707Ex Loop Calibrator » 718Ex Pressure Calibrator » 725Ex Multi-function Process Calibrator »   Ex Pressure models » 87V Ex Intrinsically Safe True RMS Multimeter »
