Newly released from Measurement Specialities and available from Variohm EuroSensor, the new generation MS45xxHRD series PCB-mountable integrated pressure/temperature sensors feature high-resolution 24-bit analogue to digital output and a wide choice of pressure ranges. Their low power consumption of just 1uA (standby <0.15uA) from a 1.8 to 3.6V supply and fast conversion to 1ms make the range particularly suited to demanding applications in process automation, altitude/air speed measurement, medical instruments and specialist leak detection or airflow equipment.
These MEMS technology sensors have very low hysteresis and high stability of both pressure and temperature signals and, with no other components required, can be interfaced to practically any microcontroller with a straightforward communication protocol. Both I2C and SPI interfaces are featured.
The MS45xxHRD series covers eight standard ranges from 0 to 1 through 150 PSI, and four ranges from 2 through 20 for inH20. A choice of absolute, gauge and differential outputs in side and top port package configurations are available through both ranges. Typical pressure accuracy is around 0.25 per cent FS and the operational temperature range covers -25 to +125degC with accuracy rated at +/- 2degC.
Media includes non-corrosive dry gases compatible with ceramic, silicon, pyrex, PPS, RTV, gold, aluminium and epoxy. Measuring just 12.5 × 9.9mm with barbed pressure ports for straightforward interconnection, the sensors can be supplied for either J-lead or thru-hole pin mounting.
Variohm EuroSensor provides complete pre-sale and post-sale application support for the Measurement Specialities range of pressure sensors. For more information on the new generation MS45xxHRD series PCB-mountable integrated pressure/temperature sensors, please visit www.variohm.com/.
