Fluke Pressure Calibrator, ±0.025% Accuracy, 500 psi Maximum Pressure Measurement - Fluke -721-1605

This pressure calibrator is a portable instrument designed for simultaneous static and differential pressure measurement in custody transfer and industrial calibration tasks. It combines dual isolated stainless-steel sensors with signal measurement and loop-power capabilities to support field verification of transmitters, flow systems and process instrumentation across a wide pressure span.

Features and Benefits:

• ±0.025% accuracy delivers precise calibration confidence
• 0.001psi resolution enables high-resolution pressure readings
• Two isolated sensors allow simultaneous differential measurement
• Internal 24V loop power supplies transmitters under test
• Measures 4-20mA and up to 30V DC for loop diagnostics
• Battery operation provides typically 35h continuous use

Applications

• Suitable for gas custody transfer calibration tasks
• Ideal for commissioning differential pressure transmitters
• Used with pressure modules to extend measurement range
• Can be used for field checks of 24V loop supplies
• Used for on-site verification of pressure sensors and gauges

What pressure ranges can it cover with different sensors?

Configurable low sensors are available at 16psi or 36psi and high sensors cover a selection from 100 to 5000psi, with combinations enabling measurement from as low as -14psi up to high-pressure limits depending on the chosen configuration.

How does it handle temperature measurement?

It accepts a Pt100 RTD input for temperature measurement when the optional RTD probe accessory is fitted, enabling combined pressure and temperature checks for custody transfer accuracy.

What power options and battery details are provided?

The instrument runs on four standard AA alkaline cells supplied with the unit and is battery powered for portable use with a typical runtime exceeding 35h

its power requirement is 6.0V DC.

Which connection and expansion options are available?

Two 1/8 inch NPT pressure ports are provided and the device can accept external 700-series pressure modules to extend measurement capability.
