| Thermal resistance and thermocouple
with Temperature transmitter |

| 1¡¢Operating principle£º |
¡¡¡¡ When using a thermal resistance or thermocouple as
a temperature-sensing element, it
receives a sensing signal through the internal measurement
circuit after sensing the c-hange in
temperature. The signal then is converted, amplified,
and compensated and cal-ibrated
correspondingly. The voltage signal after calibration
is used to control the co-nstant-current
circuit before finally outputting a DC direct-current
signal that has li-near

| 2¡¢Technical parameters£º |
 |
a¡¢The explosion-proof marks of explosion-proof products
are d relations with the temperature measured.IIBT4, l
aIICT5 and l aIICT6.
b. Insulation resistance: The resistance between the outer
terminal and outer casing of an
instrument or meter shall be notless than 50MW.
c. Limit of error
