Fluke 725EX

Fluke 725EX Power module

Product  Description：

The Fluke 725Ex is a rugged and powerful tool that combines sourcing and measuring capabilities into a single handheld device. Its most significant feature is its Intrinsically Safe (I.S.) rating, which ensures the device cannot release enough electrical or thermal energy to ignite a flammable atmosphere. The unit features a dual-channel display, allowing users to view input and output values simultaneously, which is critical for real-time transmitter calibration.

Product Parameters

• Sourcing and Measuring Range:

  • Voltage DC: Measure up to 30.000 V; Source up to 10.000 V.

  • Current DC: Measure and source up to 24.000 mA.

  • Resistance: Measure and source from 15 $\Omega$ to 3200 $\Omega$.

  • Frequency: Support for 2 CPM to 10 kHz.

• Temperature Support:

  • Thermocouples: Supports types J, K, T, E, R, S, B, L, U, and N.

  • RTDs: Supports Ni120, Pt100 (multiple standards), Pt200, Pt500, and Pt1000.

• Accuracy: High precision with typical DC voltage/current accuracy of $0.02\% + 2 \text{ counts}$.

• Power Supply: Operates on 4 AA alkaline batteries (must be type-approved for I.S. environments).

• Safety Certification: ATEX II 1 G Ex ia IIB 171°C and Class I, Division 1 Groups B-D compliance.

• Physical Dimensions: Approximately 130 x 236 x 61 mm ($5.2 \times 9.3 \times 2.4 \text{ inches}$); Weight: $0.85 \text{ kg}$ ($1.87 \text{ lbs}$).

Product Advantages

• Hazardous Area Ready: Its intrinsic safety certification allows technicians to work without a "hot work permit" in many explosive zones, significantly increasing efficiency.

• Simultaneous Functionality: The two-channel capability allows you to source current while measuring pressure or vice-versa, making it a complete solution for I/P (current-to-pressure) valve testing.

• User-Friendly Interface: The device uses a simple, push-button interface without complex menus, meaning technicians can start using it immediately with minimal training.

• Automated Testing: Features auto-stepping and auto-ramping functions for remote testing, along with a 25% stepping function for quick linearity checks.

• Pressure Calibration: When paired with optional Fluke 750PEx Pressure Modules, it can measure pressure up to $3,000 \text{ psi}$ ($200 \text{ bar}$).

Important Considerations (Precautions)

• Battery Safety: Only use type-approved batteries as specified in the manual. Never replace or install batteries while inside a hazardous or explosive area.

• Voltage Limits: Do not use the calibrator in any circuit where the voltage or transients may exceed 30 V, as this can damage the circuitry and compromise safety ratings.

• Case Integrity: Do not open the case. Any unauthorized repair or opening of the device will void its intrinsically safe certification.

• Environmental Limits: Ensure the device is used within its rated temperature range ($-10 \text{°C to } +55 \text{°C}$) to maintain measurement accuracy and safety compliance.

Product Applications

• Transmitter Calibration: Used to verify the accuracy of temperature and pressure transmitters by simulating sensor inputs and measuring the resulting $4\text{--}20 \text{ mA}$ output.

• Valve and I/P Testing: Ideal for testing control valves by sourcing a milliamp signal and measuring the resulting pressure change.

• Flow Meter Testing: The frequency and CPM (Counts Per Minute) functions are used to calibrate flow meters and pulse-output devices.

• Plant Maintenance: Routine maintenance and troubleshooting of process control loops in Petrochemical, Oil & Gas, and Pharmaceutical industries.
