The MLDX series sensors are based on All Sensors’ CoBeam2 TM Technology. This reduces package stress susceptibility, resulting in improved overall long term stability.

 

These calibrated and compensated sensors give an accurate and stable output over a wide temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air or dry gases.

 

A protective parylene coating is optionally available for moisture/harsh media protection.

 

Devices are available in 5 and 10 inH2O and 1, 5, 15, 30, and 100 PSI pressure ranges.

Specification notes

NOTE 1: FULL-SCALE SPAN IS THE ALGEBRAIC DIFFERENCE BETWEEN THE OUTPUT VOLTAGE AT FULL-SCALE AND ZERO PRESSURE

NOTE 2: OFFSET AND SPAN ERRORS RELATIVE TO THE 25°C [77°F] READING

NOTE 3: MEASURED AT ONE-HALF FULL-SCALE PRESSURE USING BFSL

NOTE 4: RESPONSE TIME FOR A ZERO TO FULL-SCALE PRESSURE STEP CHANGE, 10% TO 90% RISE TIME

NOTE 5: COMMON MODE VOLTAGE IS THE AVERAGE OF THE OUTPUT ARMS FOR VS = 10VDC

NOTE 6: INPUT RESISTANCE IS THE RESISTANCE BETWEEN VS AND GROUND

NOTE 7: OUTPUT RESISTANCE IS THE RESISTIANCE BETWEEN OUPUT+ AND OUTPUT-
