Quick and Easy Measurements

The Fluke 750PA5 AbsolutePressure Module, 0 to 30 psi, 0 to 2 bar, 0 to 200 kPa (Stainless Steel) is easy to use. To measure pressure, connect the pressure module to a pressure source or hand pump and then connect the pressure module cable to the calibrator. Apply pressure from the pressure source and it is displayed digitally on the calibrator. At the touch of a button, the pressure may be displayed in up to 11 different engineering units. When used with the 750 Series Documenting Process Calibrators, pressure readings can be date/time stamped and stored electronically for later retrieval. This saves time, eliminates errors, and supports compliance with quality standards and regulations.

Pressure Module Performance and Technology

The 750PA5 has its own microprocessor, allowing it to run the measurement circuitry and communicate digitally with a calibrator. When connected to the calibrator, the module's coefficients are uploaded from the pressure module to the calibrator. Then, as pressure measurements are made, raw sensor values for pressure and temperature are digitally loaded to the calibrator, where the raw sensor values and coefficients are manipulated to derive and display the pressure reading.

Because of this innovative technique, digital communication eliminates errors due to poor connections and electrical interference. Secondly, the modules are inherently temperature-compensated from 0° to 50°C (32° to 122°F). Lastly, the modules are fully interchangeable, because all measurements are completed in the pressure module itself and then communicated to the calibrator in digitized form.

All modules, including the 750PA5, are calibrated independently of the calibrator, and can be used with any 740, 750 or compatible 720 or 710 series calibrator. Each module has its own serial number to maintain independent traceability.

Sensor Protection in Isolated Modules

The 750PA5 incorporates a stainless steel diaphragm to isolate the sensor. With this modules, any medium that is compatible with stainless steel can be used on the high side of the module.

Rugged Construction

A urethane overmolding protects against shock if the module is accidentally dropped; it also seals against dirt, dust, and moisture.

Convenient Setup

A one-meter cable between the pressure module and calibrator reduces the length of connecting tubing to the pressure source. The remote pressure head also provides an extra margin of safety and convenience by removing the calibrator and operator from the pressure source in the event that semi-remote measurements are needed.
