MPR

SERIES

DESCRIPTION

The MPR Series is a very small

piezoresistive silicon pressure sensor

offering a digital output for reading

pressure over the specified full scale

pressure span and temperature range.

It is calibrated and compensated over a

specific temperature range for sensor

offset, sensitivity, temperature effects,

and non-linearity using an on-board

Application Specific Integrated Circuit

(ASIC). This product is designed to meet

the requirements of higher volume

medical (consumer and non-consumer)

devices, commercial appliance, and

industrial/HVAC applications.

MicroPressure Board Mount Pressure Sensors

Compact, High Accuracy, Compensated/Amplified

• Meets IPC/JEDEC J-STD-020D.1

Moisture Sensitivity Level 1

requirements: Allows avoidance of

thermal and mechanical damage

during solder reflow attachment and/

or repair that lesser rated sensors may

incur; allows long floor life when stored

as specified (simplifying storage and

reducing scrap); eliminates lengthy

bakes prior to reflow, and allows for

lean manufacturing due to stability

and usability shortly after reflow.

• Meets food safety certification for

North America, Europe and Asia (see

Table 2).

DIFFERENTIATION

• Application-specific design addresses

various application needs and

challenges.

• Digital output: Plug and play feature

enables ease of implementation and

system level connectivity.

• Total Error Band: Provides a more

comprehensive measurement of

performance over the compensated

temperature range, which minimizes

testing and calibrating every

sensor, thereby potentially reducing

manufacturing cost; improves sensor

accuracy and offers ease of sensor

interchangeability due to minimal part-

to-part variation. (See Figure 1.)

POTENTIAL APPLICATIONS

• Consumer medical: Non-invasive

blood pressure monitoring, negative-

pressure wound therapy, breast pumps,

mobile oxygen concentrators, airflow

monitors, CPAP water tanks, and

medical wearables

• Non-consumer medical: Invasive blood

pressure monitors, ambulatory blood

pressure measurement

• Industrial: Air braking systems, gas and

water meters

• Consumer: Coffee machines,

humidifiers, air beds, washing

machines, dishwashers

VALUE TO CUSTOMERS

• Very small form factor: Enables

portability by addressing weight, size,

and space restrictions; occupies less

area on the PCB.

• Wide pressure ranges simplify use.

• Enhances performance: Output

accelerates performance through

reduced conversion requirements and

direct interface to microprocessors.

• Value solution: Cost-effective, higher

volume solution with configurable

options.

FIGURE 1 . TEB COMPONENTS FOR THE MPR SERIES

Total Error Band (TEB) is a single specification that includes

the major sources of sensor error. TEB should not be

confused with accuracy, which is actually a component of

TEB. TEB is the worst error that the sensor could experience.

Honeywell uses the TEB specification in its datasheet

because it is the most comprehensive measurement of

a sensor’s true accuracy. Honeywell also provides the

accuracy specification in order to provide a common

comparison with competitors’ literature that does not use

the TEB specification.

Many competitors do not use TEB—they simply specify

the accuracy of their device. Their accuracy specification,

however, may exclude certain parameters. On their

datasheet, the errors are listed individually. When combined,

the total error (or what would be TEB) could be significant.

POWER CONSUMPTION AND STANDBY MODE

The sensor is normally in Standby Mode and is only turned on in response to a user command, thus minimizing power consumption.

Upon receiving the user command, the sensor wakes up from Standby Mode, runs a measurement in Active State, and automatically

returns to Standby Mode, awaiting the next command. The resulting sensor power consumption is a function of the sampling rate

(samples per second) as shown in Tables 6 and 7 and Figures 2 and 3.
