Temperature Transmitter 2020

The temperature transmitter adopts thermocouple and thermal resistance as the
temperature measuring element. The output signal from the temperature measuring
element is sent to the transmitter module. After voltage regulation filtering,
operation amplification, nonlinear correction, V / I conversion, constant
current and reverse After the protection and other circuits are processed, it
is converted into a 4 ~ 20mA current signal with linear relationship to
temperature 0-5V / 0-10V voltage signal, and the RS485 digital signal is
output.

Introdcution to high temperature pressure transmitter If the transmitter
consists of two sensors used to measure the temperature difference, there is a
given continuous function relationship between the output signal and the
temperature difference. It is called temperature transmitter.
There is a given continuous function relationship (usually a linear function)
between the output signal of the transmitter and the temperature variable. The
output signal of the transmitter produced in the early stage has a linear
function relationship with the resistance value (or voltage value) of the
temperature sensor.

Advantages of temperature indicator transmitter The integrated temperature
transmitter has the advantages of simple structure, lead saving, large output
signal, strong anti-interference ability, good linearity, simple display
instrument, anti-vibration and moisture-proof solid module, reverse connection
protection and current limiting protection, and reliable operation.
The output of the integrated temperature transmitter is a unified 4 ~ 20mA
signal; it can be matched with the microcomputer system or other conventional
instruments. It can also be made into explosion-proof or fire-proof measuring
instruments according to user requirements.
Types and Components of Temperature Transmitter
Transmitter has electric unit combination instrument series and miniaturized
modular type, multi-function intelligent type. The former does not have
sensors, the latter two types of transmitters can be easily combined with
thermocouples or thermal resistances to form transmitters with sensors.
The integrated thermal resistance temperature transmitter is a relatively small
temperature transmitter that can be installed in the junction box of the
thermal resistance. The integrated temperature transmitter is generally
composed of a temperature measuring probe (thermocouple or thermal resistance
sensor) and a two-wire solid electronic unit. The temperature probe is directly
installed in the junction box in the form of a solid module, thereby forming an
integrated transmitter. Integrated temperature transmitters are generally
divided into two types: thermal resistance and thermocouple type.
Thermal resistance temperature transmitter is composed of reference unit, R / V
conversion unit, linear circuit, reverse connection protection, current limit
protection, V / I conversion unit, etc. After the thermal resistance signal of
temperature measurement is converted and amplified, the nonlinear relationship
between temperature and resistance is compensated by a linear circuit, and a
constant current signal of 4 to 20 mA in linear relationship with the measured
temperature is output after the V / I conversion circuit.
