Temperature Sensor
Temperature Sensor is a new type of temperature sensor consisting
of junction box and multi-point thermocouple element, mounting
fixture, secondary sealing chamber, leakage detection device and
other major components.
Multi-point thermocouple elements for multiple element distribution
and armored multi-point thermocouples for multiple element
combination processing into a single unit.；
It is widely used for temperature measurement in synthesis towers,
reaction tanks, high-pressure hydrogenation and other media at
different depths and in different locations at the same time.
Fast response, high accuracy, shock resistance and corrosion
resistance.
Simultaneous measurement of temperature measurement points at
different depths and locations.
Thermocouple: 3 to 15 points, more than 15 points supplied by
agreement.
RTD: 3 to 8 points, more than 8 points supplied by agreement.
Main Technical Parameters:
Grading number: K, N, E, Pt100
Temperature measurement range: -200℃～800℃ (according to the
specific index number)
