High-temperature DAQ evaluation module from TI to design products for harsh conditions
Texas Instruments Incorporated has introduced the H.E.A.T.
(harsh environment acquisition terminal) evaluation module
(EVM), a high-temperature data acquisition system for extreme
temperature. The H.E.A.T. EVM is test-oven ready and qualified
to operate up to 200 hours at oven temperatures of up to
200ºC.
H.E.A.T.EVM uses eight channels of analog data and conditions,
digitizes and processes these signals for a variety of applications
in ruggedized, high-temperature environments including downhole
drilling, jet engines and heavy industrial applications
says TI.
According to TI H.E.A.T. EVM eliminates the need for expensive
up-screening and qualification testing of industrial-grade
components for temperature ranges outside their datasheet
specifications quickly and safely and cuts development,
testing and qualification time by up to one year in harsh
environments.
Key features and benefits of the H.E.A.T. EVM as per TI
include:
Six channels optimized for temperature, pressure sensors
and accelerometers plus two general-purpose channels (fully
differential and single-ended).
Comprehensive set of components qualified for operating
temperatures from -55ºC to 210ºC and guaranteed
for at least 1,000 hours operating life.
