Pressure Sensor Modules from Meriam Process Technologies are available in a several types and ranges to provide the ultimate in flexibility and convenience for portable calibration standards. Meriam pressure modules are used with any MFT 4000 Series Multi-Function Tester by installing modules into any of three (3) MFT sensor bays. The modules are completely interchangeable to facilitate most pressure testing needs (restrictions on module installation and removal apply to Intrinsically Safe MFT units). NIST traceable accuracy of ± 0.025% FS is available for most pressure ranges and types. This accuracy statement includes all effects of linearity, hysteresis, repeatability and temperature from 23°F to 122°F (no partial temperature compensation here!). A NIST certificate and calibration data are included with each module for quality assurance purposes.

Pressure Measurement Module Advantages
Calibration coefficients for all modules are stored in non-volatile sensor module memory. This means any pressure module can be used in any Meriam MFT without manual programming of coefficients. When a module is installed and the MFT is powered up, the MFT senses the module bay connection, polls the module for the calibration coefficients and configures the display for pressure readout in the last engineering unit selected. Engineering units, including PSI, centimeters or inches of H2O (at 4°C, 20°C, or 60°F), kg/cm2, kPa, mBars, Bars, millimeters, inches of Hg (at 0°C ref. temp) and oz/in2 are all selectable from the MFT keypad. Meriam sensor modules are designed to be re-calibrated in the field with appropriate local calibration standards. The MFT’s Rcal feature allows customers to adjust zero (offset) and full scale (gain) plus up to seven (7) addition points on the calibration curve. Dead weight testers are generally used to apply a known pressure to a module. The Rcal feature allows the user to key in the applied pressure value, which lets the module know how to correct its calibration curve. Meriam also provides factory re-calibration services for pressure modules including complete documentation and certification.
