New range
of integrated 24-bit pressure/temperature PCB-mount sensors available
from Variohm
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 1 µA (standby <0.15
µA) from a 1.8 to 3.6V supply and fast conversion to 1
ms make the range particularly suited to demanding applications
in process automation, altitude/air speed measurement, medical
instruments and specialist leak detection or airflow equipment.
The 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% FS and the
operational temperature range covers -25 to +125ºC with
accuracy rated at +/- 2ºC.
Media includes non-corrosive dry gases compatible with ceramic,
silicon, pyrex, PPS, RTV, gold, aluminium and epoxy. Measuring
just 12.5 x 9.9 mm 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
and also designs, develops and sources a broad range of position,
load, force, and other sensor technologies for demanding measurement
applications throughout industry, agriculture, construction,
autosports, and research.
