1.USE
Bimetallic thermometer is
an industrial meter applicable to measure medium and low temperature in petrochemical mineral
well, metallurgy, textile, military industry, pharmacy,
food etc. It can be used to directly show the temperature of gas, liquid
and vapour.
Bimetallic thermometer has the advantages:quick in reaction,easy in reading shockproof ,free of mercury pollution, stable performance,long in service,the class of casing protection upto IP65 etc.It can substitute industrial glass mercury thermometer being widly applicable to varis fields.
2.Configuration
Bimetallic thermometer consists of
Bimetallic thermometer-sensitive element, supporting pipe,
connector, indication scale etc. Bimetallic thermometer-sensitive element is to use multi-coil straight spiral bimetallic strip one end is fixed another end cfree end,is connectted on core axle.When the temperature varies,the free end of temperature-sensitive element rotates.via core axle to drive the needle on the scale to indicate the change value of the measured media temperature .Bemetallic thermometer is divided into 3 types-axial type,radial type,and universal type according to the stucture,or 4 types-common type,(sole index),with electric joint,remote transmission and with noctilucence accordingto the function. |

·Ambient
temperature -40～+85℃, Comparatively humidity

·In
general, the length for the supporting pipe to be submerged
into the medium being measured is bigger than 100mm so
as to ensure the accuracy.
·The
maximum surface temperature is 400℃ when the scale
plate’s diameter is 60.

Operation & Maintenance:
1. In the storage, operation and installation of
the bi-metal thermometer, it should avoid supporting tube from collision do not bend and deform the supporting tube take
the meter case
as a spanner.
2. Do not use various bi-metal thermometers
to measure the medium temperature in an opened container. The
thermometer with electric connections is not allowed to work
under a strong shock so as not to influence the connections’
reliability.
3. Use JX series protective pipe in
the case the pressure is higher than 1.5Mpa.
Notes:In Ordering
1. At order,
please make note on the product model, measuring range, way
of connection, norm, inserted depth, casing diameter, accuracy
class, outer diameter of support pipe etc.
2. Please make a detailed note in case
of a special requirement.
