Are you looking for silicon temperature sensor related product information? Huaheng Instrument supplies you with the price,
supply and supplier of all kinds of silicon temperature sensor supply product information.
Welcome to Huaheng Instrument,
the new silicon temperature sensor offer is available in the Octagon resource network.
Silicon temperature sensor,
when two identical transistors operate with a constant collector current density ratio,
their base-emitter voltage difference is only proportional to absolute temperature.
Other temperature sensors,
are based on the behavior of the base-emitter voltage VBE,
of a diode-connected transistor,
which changes very with temperature.
When two identical transistors operate with a constant collector current density ratio,
their base-emitter voltage difference is only proportional to the absolute temperature.
Other temperature sensors are based on the behavior of the base-emitter voltage VBE,
of a diode-connected transistor.
This VBE changes with temperature,
and the rate of change is very constant at -2mV / °C,
but for different transistors.
The absolute value of the VBE change is also different.
To compensate for this variation, ΔVBE can be compared at different IE values.
Some silicon temperature sensors produce simulations
The voltage output (VPTAT, which is proportional to the absolute temperature),
while other temperature sensors convert VPTAT to current output.
In the digital output temperature sensor,
the VBE of the detection transistor is amplified,
then compared with the bandgap reference voltage,
and the result is input to the Σ-Δ or successive approximation register ADC,
to be converted into a digital output,
and the precision can be 13 bit or 16 bit, of which the least effective Bits are used as sign bits.
An alternative digital output scheme is to use pulse width modulation (PWM),
whose temperature is proportional to the ratio of the on and off times of the pulses.
Since the on-time is fixed,
these sensors can perform a single measurement as needed to cut power consumption.
The silicon temperature sensor,
is one of the temperature transmitter products of Huaheng Instrument. Huaheng Instrument manufactures various types of temperature transmitters and temperature sensors.
Products that are also developed according to the silicon principle,
as well as high accuracy pressure transducers.
The high accuracy pressure transducers produced by Huaheng Instrument,
can be used for high-precision pressure measurement products in harsh environments.
