What's New! Pressure - Autumn 2024

# MPM288DI Pressure & Temperature Sensor with Digital Output The **MPM288DI** stands out as a cutting-edge pressure sensing solution, featuring a robust 316L stainless steel piezoresistive element. It delivers high-resolution dual 24-bit outputs for both pressure and temperature measurements via an I²C digital interface. This pressure sensor is housed in a compact yet durable 19mm package, crafted from 316L stainless steel with FKM O-ring materials for enhanced reliability. With a standard pressure range spanning from 0 to 350 mbar up to 35 bar (500 psi), it offers flexible gauge or absolute pressure reference options. Its precision reaches an impressive 0.2% full-scale accuracy, ensuring reliable performance across a broad temperature spectrum. Designed specifically for energy-efficient applications, the MPM288DI includes a dedicated power control pin and consumes minimal standby current (<100 nA), extending battery life significantly while maintaining top-tier resolution. This sensor can be customized to meet specific requirements, such as compatibility with mains or drinking water systems, programmable I²C addresses, O-ring materials, cable configurations, and connectors. Calibration data can also be provided electronically upon request. --- # MPM2581 Pressure & Temperature Sensor with Digital Output The **MPM2581** represents a highly compact digital pressure and temperature sensing solution, housed in a 16mm body. Featuring a 14-bit resolution for pressure and an 11-bit resolution for temperature, it supports either I²C or SPI digital interfaces, allowing users to configure the part number based on their needs. Constructed using 316L stainless steel and equipped with an EPDM O-ring as standard, this sensor is built to last. The standard pressure range spans from 0.5 psi (350 mbar) to 500 psi (35 bar), offering both gauge and absolute pressure references. With the option of operating on either 3.3V or 5VDC supplies, it is ideal for battery-powered devices while maintaining low power consumption. The MPM2581 can be fully tailored to meet application-specific demands and serves as a seamless drop-in replacement for similar 16mm digital output sensors currently in use. --- # MPM288SA Analog Output Pressure Sensor The **MPM288SA** combines high-resolution analog output capabilities with a piezoresistive design, delivering current or voltage outputs via an ASIC chip mounted on a PCB. This versatile pressure sensor measures just 19mm in diameter and comes fully temperature-compensated, offering pressure range options from -1 mbar to 350 mbar up to 700 bar, whether absolute or gauge referenced. The MPM288SA provides multiple output formats, including a 2-wire 4-20 mA DC current output, a fixed 3-wire 0.5-4.5 VDC voltage output, or a ratio-metric 3-wire voltage output. Powered by the latest-generation conditioning chip (ASIC), it features dual-channel 24-bit ADCs for exceptional signal resolution. Its performance remains stable under varying temperatures and conditions, thanks to advanced thermal aging compensation and wide-range temperature adjustments. Customization options include cable/connector types, O-ring materials, and all-welded thread designs, making it adaptable to a variety of industrial applications. --- # MPM281Pro High-Accuracy Pressure Sensor The **MPM281Pro** embodies precision engineering with its 0.1% high-accuracy, media-isolated piezoresistive pressure-sensitive element. Encapsulated within a robust 316L stainless steel structure, it boasts a 19mm outer diameter. By utilizing a constant current power supply, this sensor achieves precise temperature error correction and zero output through an external laser-trimmed compensation board. Additionally, the gain resistance can be fine-tuned to deliver a net full-scale output signal of 3.012V ±1%. Pressure ranges extend from as low as 1 psi (0.07 bar) to 35 bar (500 psi), with both gauge and absolute pressure reference options available. The lower-pressure ranges exhibit superior overpressure tolerance. Tailored to fit unique project needs, the MPM281Pro can be customized accordingly. --- For further details or technical support, feel free to **contact us** anytime.
