The new Fluke 750p series of pressure module is a complete family of over 48 pressure modules that can perform pressure calibrations from vacuum to 1 in H20 to 10000 PSIG. Gage pressure modules have one pressure fitting and measure the pressure with respect to barometric or atmospheric pressure. Differential pressure modules have two pressure ports and measure the difference between the applied pressure on the high fitting versus the low fitting. Each module is clearly labeled for range, overpressure and media compatibility. All modules include appropriate adapters to connect NPT, metric (BSP) and M20 threads. To measure pressure, connect the pressure module to a pressure source or hand pump and then connect the pressure module cable to a compatible Fluke 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.
Pressure module performance and technology Fluke 750P Series pressure modules are highly accurate, with specifications that apply from temperature range of 0 °C to 50 °C (32 °F to 122 °F. Many ranges have total uncertainties of 0.04 % of full scale and reference uncertainties of 0.01 % of full scale (see specification tab for details). Fluke pressure modules use silicon piezo-resistive sensors which consist of a resistive bridge fabricated in a silicon diaphragm. Each module has its own microprocessor, allowing it to run the measurement circuitry and to communicate digitally with the calibrator. When connected to the calibrator, the modules 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 high accuracy pressure readings. This innovative technique provides several benefits: 1. Digital communication eliminates errors due to poor connections and electrical interference. 2. The modules are fully temperature compensated from 0 °C to 50 °C (32 °F to 122 °F). 3. The modules are fully interchangeable because all measurements are completed in the pressure module itself and then communicated to the calibrator as a digitized signal. Modules 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 calibration tacking and traceability. A heavy duty urethane molded cover protects against shock if a module is accidentally dropped and also seals against dirt, dust, and moisture. Pressure connections are 1/8” NPT female connection. A ¼” NPT Male, ¼” BSP/ ISO and M20 male adapter are also provided with each pressure module allowing the user to connect to most common threads encountered.
