Description Temperature Transmitter 2088
The temperature transmitter is composed of a temperature sensor and
a signal converter. The signal converter is installed in the cold
terminal junction box of the temperature sensor. The temperature
sensor is affected by temperature to produce resistance or
potential effect, and a differential voltage signal is generated
after conversion. This signal is amplified by the amplifier, and
then converted by voltage and current, and outputs a current signal
of 4-20mA or other signals of 0-5V/0-10V corresponding to the
range.
The temperature transmitter organically integrates the temperature
sensing element (thermal resistance or thermocouple) with the
signal conversion and amplification unit, and is used to measure
liquid, steam and other gaseous media in the range of -200-1600 °C
in various processes. The temperature of the solid surface. It is
usually used in conjunction with display instruments, recording
instruments and various control systems. It has the characteristics
of simple structure, convenient installation, use and maintenance,
and has been widely used in petroleum, chemical, metallurgy, power
stations, light industry and other departments.
Temperature transmitters are divided into three categories:
ordinary type, explosion-proof type and digital display
integration. Among them, ordinary type and flameproof type can
choose different built-in temperature transmitter modules to meet
different application requirements of users. According to different
temperature sensors, temperature transmitters are divided into two
series: thermocouples and thermal resistances

Feature Temperature Transmitter 2088
1.Two-wire transmission is possible. The two wires that power the
signal converter also carry the output signal
2.Output constant current signal or constant voltage signal, with
strong anti-interference ability and good remote transmission
performance.
3.The signal converter is encapsulated into a module with epoxy
resin, which has the advantages of anti-vibration, corrosion
resistance and moisture resistance, and can be used in places with
poor conditions.
4.The resistance signal or millivolt signal of thermal
resistance/thermocouple is directly converted into 4-20mA current
output by the signal converter, and the signal is transmitted by
ordinary cable, which can save the expensive compensation wire.
5.The temperature transmitter with on-site display can not only
output a current signal of 4-20mA, but also read the measured
temperature at the temperature measurement site, which brings great
convenience to the operator.
6.High precision, anti-interference, good long-term stability,
maintenance-free, and remote transmission (up to 1000 meters).
