BETA offers 24 standard pressure modules, covering gauge, vacuum, absolute, compound,
and differential measurements. All modules are directly compatible with the BetaGauge II and
the BetaFLEX. With the Model BPPA-100 BETA Port Pressure Adapter, the modules are fully
compatible with the BETA 950, BETA 850, Martel MC-1200, Martel MC-1000, and Martel M2001. Pressure ranges may be displayed in any of 13 user-selectable units.
Water density correction factors of 4 °C, 20 °C, or 60 °F can be selected for either water column unit. The choice of pressure unit may be restricted by limitations on resolution of the instrument display.

• 24 standard ranges

• Gauge, vacuum, absolute, compound, and differential measurements

• Accuracy specified over 15C to 35C range

• Isolated and non-isolated measurements,
  range dependant

Notes:

1. Accuracy is percent of full scale range, over the 15 ° C to 35 ° C temperature range. Includes the pressure/temperature hysteresis in psi, where listed, for six months from date of last calibration. The accuracy statement shown in the specification table is the base accuracy from
   15 ° C to 35 ° C. Outside this temperature range, add an additional ± 0.0015% of FS per ° C.
   To calculate the allowed deviation of a particular BETA Pressure Module, use the following formula:
   Deviation = ± %FS , ± T/P H, ± tempco
   Where ± T/P H = thermal/pressure hysteresis in psi where applicable, 
   and ± tempco = ± 0.0015% FS/° C when the temperature is outside the 15-35 ° C temperature range

2. The Gauge, Vacuum, and Compound type range measurements are relative to atmospheric pressure. The Absolute type is a measurement made relative to absolute zero (perfect vacuum). The Differential type is a measurement made relative to the pressure applied to the low-pressure port of the module.

3. Units for display: pounds per square inch (psi), millibars (mbar), kilopond per square centimeter (kp/cm2, also kg/cm2), atmospheres physical (Atmos), kiloPascals (kPa), MegaPascals (MPa), inches of Mercury @ 0 ° C (InHg), millimeters of Mercury@ 0 ° C (mmHg), inches of water column (InWC), centimeters of water column (cmWC), or one user-defined pressure unit.

4. These extended ranges are drerated because the calibrated range of the module does not match the range of the sensor.

5. The maximum static pressure is 200 psig (14 bar).

6. Relative to the calibration standard.

7. Thermal and pressure hysteresis = 0.0025 PSI (0.1724 mBar)

8. Thermal and pressure hysteresis = 0.0030 PSI (0.2068 mBar); all other ranges = no hysteresis

9. 0 to 7.2 PSI, 0 to 150 PSI, and 0 to 1500 PSI are extended ranges.

10. Gauge, Absolute, and Compound types are isolated and accept any media compatible with 316SS. Vacuum and Differentiated types are compatible with pressure media that are clean, dry, non-corrosive air or gas.
