Product catalog summary
Features
The MPR Series MicroPressure Board Mount Pressure Sensors are compact sensors with a 5 mm x 5 mm footprint, offering calibrated and compensated pressure readings from ±40 mbar to ±2.5 bar, ±4 kPa to ±250 kPa, or ±0.6 psi to ±30 psi. They provide a 24-bit digital output compatible with I2C or SPI interfaces, suitable for IoT applications. The sensors consume low power (<10 mW typical) and feature a stainless steel pressure port with medical and food-grade gel options. They are compatible with various liquid media and available in absolute and gage pressure types, with a Total Error Band as low as ±1.5 %FSS. Operating within a compensated temperature range of 0ºC to 50ºC, they comply with REACH and RoHS standards and meet IPC/JEDEC J-STD-020D.1 Moisture Sensitivity Level 1.
Differentiation
The MPR Series is designed for specific application needs with a digital output that simplifies implementation and connectivity. The Total Error Band ensures true performance over the compensated temperature range, reducing the need for individual sensor testing and calibration, thus lowering manufacturing costs and improving accuracy and interchangeability.
Potential Applications
The sensors are suitable for consumer medical applications like non-invasive blood pressure monitoring and medical wearables, non-consumer medical applications such as invasive blood pressure monitors, and industrial uses like air braking systems. They are also applicable in consumer products like coffee machines and humidifiers.
Portfolio
The MPR Series is part of a broad range of board mount pressure sensors for medical, industrial, and consumer applications.
Description
The MPR Series sensors are small piezoresistive silicon pressure sensors with digital output, calibrated and compensated for offset, sensitivity, temperature effects, and non-linearity using an on-board ASIC. They are designed for high-volume medical and commercial appliance applications.
Value to Customers
The sensors' small form factor supports portability and space efficiency on PCBs. They offer wide pressure ranges, enhanced performance through direct microprocessor interfacing, and cost-effective solutions with configurable options. They meet moisture sensitivity requirements, allowing for stable and lean manufacturing processes. Their low power consumption extends battery life.
General Specifications
The sensors operate with a supply voltage of 3.0 to 3.6 Vdc and have a power consumption of 10 mW. They function within an operating temperature range of -40°C to 85°C and a compensated temperature range of 0°C to 50°C. The startup time is 0.3 ms, and they support a data rate of 200 samples per second.
Environmental Specifications
The sensors can withstand humidity levels from 0% to 95% RH (non-condensing) and 0% to 100% RH (condensing for liquid media options). They are resistant to vibration and shock and meet solder reflow standards.
Wetted Materials
The sensors use 304 stainless steel for ports and covers, with options for gel protection.
Pressure Types
The sensors are available in absolute and gage pressure types, with outputs proportional to the difference between applied pressure and a reference.
Operating Specifications
The sensors have a supply voltage range of 3.0 to 3.6 Vdc, with a standby current of 0.0005 mA and an active mode current of 1.7 mA. They offer a Total Error Band of ±1.5 %FSS and an accuracy of ±0.25 %FSS.
General Overview
The document provides detailed technical specifications and operational guidelines for Honeywell's MicroPressure Board Mount Pressure Sensors, MPR Series. It includes information on available configurations, pressure range specifications, and communication protocols.
Pressure Range Specifications
The document outlines pressure range specifications for various units including mbar, kPa, and psi. Each specification includes details on overpressure, burst pressure, and total error band after customer auto-zero. Overpressure is the maximum pressure the product can handle without damage, while burst pressure is the maximum pressure before the product fails.
Start-up and Power Supply Requirements
The MPR Series sensors require a specific start-up timing and power supply conditions. The sensor can receive commands 1 ms after power-up and begin measurements 2.5 ms after the VDD supply is operational. The power supply must meet a minimum VDD rising slope of 10 V/ms.
I2C Communication
The document details the I2C communication protocol, including data transfer, sensor addressing, and timing parameters. The MPR Series sensors operate as slaves and respond to master requests, outputting up to 4 bytes of data. The default I2C address is 0x18, with other standard addresses available.
SPI Communication
The SPI communication section describes the full-duplex mode operation between a master and slave. The MPR Series sensors output up to 4 bytes of data, with the first byte being the status byte. The document provides a detailed explanation of SPI data transfer and timing parameters.
Figures and Tables
The document includes several figures and tables illustrating product nomenclature, pressure range specifications, I2C and SPI reference circuits, and timing diagrams. These visual aids help clarify the technical details and operational procedures.
Pressure Sensor Output Calculation
The MPR Series sensor output is determined using a transfer function. The pressure can be calculated by rearranging the transfer function equation. Key variables include Outputmax, Outputmin, Pmax, Pmin, Pressure, and Output. An example calculation is provided for a sensor with a range of -1 psi to 1 psi and a calibration from 10% to 90%.
Product Dimensions and Layout
Figures 9 and 10 provide dimensions and recommended PCB pad layout for the MPR Series sensors. Dimensions are given in millimeters and inches for both long and short port configurations.
Pinout and Functionality
Table 9 details the pinout and functionality of the sensor, including SS, MOSI/SDA, SCLK/SCL, VO+ and VO-, MISO, EOC, RES, VSS, and VDD.
Warnings and Additional Information
Warnings are provided against using the product as a safety or emergency stop device. The document is not to be used as an installation guide. Additional literature and warranty information are available on the Honeywell website.

MicroPressure Board Mount Pressure Sensors - MPR Series-3

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...
