The P5514B Hydraulic Pressure Comparator is a simple, robust and economical pressure comparison test pump for calibrating gauges, switches and transducers with precise, fine adjust capabilities. It generates pressure to 10 000 psi (70 MPa), with a new Vernier fine-adjustment control that enables cardinal point calibrations. The P5514B can be mounted easily on a bench or used in mobile applications. Its robust design, with improved reservoir valve sealing, makes it a more stable pressure generator than previous versions of this model. Test port connections include adapters for common sizes of NPT and BSP. Connections are tool free, no sealing tape required, another design improvement which, coupled with the new Vernier fine adjustment control, simplifies and improves pressure testing.
About pressure comparison test pumps

A pressure comparison test pump or pressure comparator supplies the same precisely controlled pressure to both a reference gauge and device under test for calibration. Fluke Calibration hydraulic test pumps are used for checking pressure measuring instruments against master test gauges, indicators or transducers. These cost-effective instruments, which include several features from our popular line of hydraulic deadweight testers, are capable of easily generating high pressures and often include a Vernier for precise control for important calibration requirements.
Make it a pressure calibrator

The Fluke Calibration P5514B Hydraulic Comparison Test Pump, when combined with the 2700G Reference Pressure Gauges, becomes an easy-to-use alternative to traditional deadweight testers that covers a wide range of workload. For convenience, the P5514B is bundled together with selected 2700G Reference Pressure Gauges for a complete bench top pressure calibration solution. These pressure calibrators provide the accuracy, reliability, and capability you need to calibrate dial gauges, digital test gauges and pressure transmitters.
For example, the P5514B-2700G-3 is a P5514B comparison test pump, bundled together with 2700G-G70M, 2700G-G20M, 2700G-BG7M. This calibrator has three pressure ranges corresponding to the three 2700G Reference Pressure Gauges in the bundle and covers a total pressure range of –12 psi to 10 000 psi (–80 kPa to 70 MPa).

Simplify complex motor drive troubleshooting with guided test setups and automatic drive measurement that provide reliable, repeatable test results.

The Fluke MDA 550 Motor-Drive Analyzer saves time and the hassle of setting up complex measurements, and simplifies the troubleshooting process. Simply select a step-by-step guided test and measurement will show you where to make voltage and current connections, while preset measurement profiles ensure you will get all the data you need for every critical motor drive part, from input to output, the DC bus, and the motor itself . Doing simple to complex measurements? MDA-550 can do it. What's more, making reports before (as-found) and after (as-left) repairs or adjustments becomes more practical. This is all thanks to its built-in report generator feature.



The MDA-550 is an ideal portable motor drive analysis testing tool. Not only that, this tool can also be used to safely detect and solve common problems in inverter-type motor drive systems.



- Measures main motor drive parameters , including voltage, current, DC bus voltage level and AC ripple, voltage and current unbalance and harmonics, voltage modulation, and motor shaft voltage discharge.

- Performs broader harmonic measurements to identify the impact of low and high order harmonics on your power system.

- Performs guided measurements of motor drive input, DC bus, drive output, motor input, and shaft measurements with step-by-step graphical diagrams of voltage and current connections.

- Quickly and easily generate reports that are perfect for documenting problem solving and collaborative work with others.

- Measure additional electrical parameters with a complete 500 MHz oscilloscope, meter and logger capability for a wide range of electrical and electronic measurements in industrial systems



The Fluke MDA-550 Motor Drive Analyzer uses guided test measurements to make analysis even easier



Drive input



Quickly measure input voltage and current to see if values ??are within acceptable limits by comparing the rated voltage to the actual supply voltage. It then checks the input current to determine if the current is within its maximum rating and the conductor size is appropriate. You can also check if the harmonic distortion is within an acceptable level. There are two options for doing this: carefully examine the shape of the waveform or look at the harmonics spectrum screen which displays total harmonic distortion and individual harmonics.



Imbalance of voltage and current



Check the voltage unbalance at the input terminals so you can make sure the voltage unbalance is not too high (> 6-8%), and the phase rotation is correct. You can also check for current unbalance, as too large an imbalance can indicate a driving rectifier problem.



Wider harmonic measurement



Excess harmonics are not only a threat to your rotating machine, but also to other equipment connected to the mains power system. As well as being able to detect motor drive harmonics, the MDA-550 can also detect the potential impact of inverter switching electronics. The MDA-550 has three harmonic ranges, 1st to 51st harmonics, 1 to 9 kHz, and 9 kHz to 150 kHz providing the ability to detect harmonic pollution problems.



Bus DC



In motor drives, the conversion of AC to DC inside the drive is very important. The reason is that for the best drive performance it is necessary to have the right voltage and adequate smoothing with low ripple. High ripple voltages can be an indicator of a faulty capacitor or a faulty motor connected. The logging function can be used to dynamically check the performance of the DC bus in operating mode when load is applied.



Drive output



Check drive output focusing on voltage to frequency (V/F) ratio, and voltage modulation. If the V/F ratio is high, the motor may overheat. With a low V/F ratio, the connected motor may not be able to provide the torque required at the load to carry out the process for which it is intended.



Voltage modulation



Pulse Width Modulation signal measurements are used to check for high voltage peaks that can damage motor winding insulation. The rise time or steepness of the impulse is indicated by a dV/dt reading (value of change in voltage over time), this must be compared with the specified motor insulation. Metering can also be used to measure switching frequency. Its purpose is to detect whether there is a potential problem with the switching electronics, or with grounding, as the signal drifts up and down.



Input Motor



Ensuring the supply of voltage at the motor input terminal is important. However, choosing a connecting cable between the drive and the motor is no less important. Incorrect cable selection can cause damage to the drive and motor due to overvoltage peaks. Checking that the current at the terminals is within the motor's rating is critical because excess current can cause the motor to overheat, reducing the life of the stator insulation which can cause premature failure of the motor.



Motor shaft voltage



The voltage impulse in the variable speed drive is generated from the circuit between the motor stator and the rotor until a voltage appears on the rotor shaft. If the rotor shaft voltage exceeds the insulating capacity of the bearing grease, flashover currents (glow) may occur. As a result, pitting and fluting of the motor bearing rotation occurs, namely damage that causes the motor to fail prematurely. The MDA-550 is equipped with a carbon fiber brushed probe tip that makes it easy for you to detect destructive flashover currents. Meanwhile, the amplitude of the impulse and the number of events can be used as a consideration in taking preventive action. With the addition of these accessories and capabilities, you can spot potential faults without the need to buy expensive permanent solutions.



Step-by-step guided measurements ensure you have the data you need, when you need it



The MDA-550 is designed to help you quickly and easily test and troubleshoot common three-phase and single-phase inverter-type motor drive systems. Onscreen information and a step-by-step setup guide make it easy for you to configure the analyzer. Not only that, the information and guide will also provide the required drive measurements. That way, you can quickly make informed decisions regarding maintenance. From power input to attached motor, the MDA-550 provides measurement capabilities for the fastest motor drive solutions.
