Description WSS temperature thermometer bimetal oil temperature gauge
WSS series bimetal thermometer is a field detection instrument for measuring medium and low temperature. The bimetal thermometer can directly measure the temperature of liquid, steam and gas medium in the range of -80℃～+500℃ in various production processes.
The bimetal thermometer uses a threaded thermal bimetallic sheet as
a temperature sensing device, and installs it in a protective
sleeve. One end is fixed, called the fixed end, and the other end
is connected to a thin shaft, called free end. A pointer is mounted
on the free end spool. When the temperature changes, the free end
of the temperature sensing device rotates accordingly, driving the
pointer on the thin shaft to change the angle, and indicating the
corresponding temperature on the dial.
Specification WSS temperature thermometer bimetal oil temperature gauge
The advantages of bimetal thermometers are fast response, small
size, good linearity and stability, and some foreign products also
have high temperature performance.
The thermoelectric potential of the bimetal thermometer is only
related to the thermoelectric properties of the hot electrode
material and the temperature difference between the two ends.
Using the same homogeneous conductor or semiconductor to form a
circuit will not generate thermoelectric potential.
The temperature of the two junctions of the thermocouple is T, T0.
If T=T0, the thermoelectric potential of the thermocouple is zero.
The law of intermediate temperatures provided the basis for the
development of thermocouple scales.
If the two conductors A and B are respectively formed with the
third conductor, the thermoelectricity has a wide temperature
measurement range, and the physical and chemical properties of
long-term use are stable.
High conductivity, small temperature coefficient of resistance;
※The thermoelectric potential of the configuration is highly
sensitive, and the thermoelectric potential and temperature are
linear, easy to copy, simple in process and cheap in price.
But the compensation bridge matched with
nickel-chromium-nickel-silicon was wrongly used, and the balance
point of the compensation bridge was 0º C. When the
temperature of the cold end is 30º C, and the thermometer
indicates a temperature of 900º C, what is the actual
temperature of the heating furnace? Use the standard electrode law
to determine the components that change with temperature.
Generally, bimetal thermometers are used at low temperatures, and
thermocouples are used at high temperatures. If the temperature
exceeds 500 degrees, the resistance of the bimetal thermometer will
be very large, which may affect the measurement results, and even
the measurement results cannot be obtained.
