Semiconductor & IC Thermometer
Device Vendors
Semiconductor thermometers are usually produced in the form of
ICs, Integrated Circuits. There are many types, sizes and models. Most are quite
small and their fundamental design results from the fact that semiconductor diodes
have voltage-current characteristics that are temperature sensitive.
That means
that semiconductor triodes or transistors are also temperature sensitive. Needless
to say, there devices have temperature measurement ranges that are small compared
to thermocouples and RTDs, but,
they can be quite accurate (e.g. ± 0.5°C or so) and inexpensive and very easy to interface with other
electronics for display and control.
Listed below are links to
some of the makers and suppliers of semiconductor thermometer devices Thanks
for visiting.
- AdSem, Inc..
Supplier of novel Si and Ge NTC thermistors with unique performance: the highest operating temperature, the widest interchangeability temperature range, the highest thermosensitivity, the smallest size and universal R-T dependence.
AdSem, Inc. is only company in the world that offers semiconductor temperature sensors that function as Negative Temperature Coefficient thermistors rather than diodes. They also offer the smallest semiconductor RF and low-temperaturre IR bolometers.
- Analog
Devices.
One
of the giants in specialized IC devices is also one of the leaders in innovative
IC temperature sensor packages and a-to-d converters.
-
Maxim Integrated Circuit Devices
One of the most innovative (in terms
of sensors) with temperature sensors, micro-sized temperature dataloggers, humidity
sensors, sensor kits for low cost exploration of packaging and implementation
of new sensor/logger designs-like a miniature weather station.
-
MicRed
THERMOSENS Family of CMOS compatible, process independent temperature
sensors with either analog or digital output.
- National
Semiconductors
Yes, that National Semiconductors, one of the largest of
integrated circuit makers for standard ic op-amps, a-to-d converters, counters,
timers and then a whole passle of digital devices
-
Sensirion
Develops and markets CMOS sensors for temperature measurement,
differential pressure, humidity, mass, air and gas flow
- Thermochron
Their web site is dedicated to the iButton temperature sensor & data logger
featured as the product of the month for January 2002 on this web site.
- TPI
Corporation
A manufacturer of digital temperature and pressure sensors
that connect directly to digital I/O ports and micro-PLC's.
