Description
I. Product Overview
The WR K armored thermocouple has the advantages of bending, high pressure resistance, fast response and strong durability. The armored thermocouple is the same as the assembled thermocouple. As a sensor for measuring temperature, the armored thermocouple usually matches the display of the thermocouple and the display instrument, the recorder and the electronic regulator. At the same time, the armoured thermocouple can also be used as the temperature sensing element of the assembled thermocouple. The armored thermocouple can directly measure the temperature of liquid, steam and gas medium and solid surface in various production processes ranging from 0 to 1100 degrees.
Two. Main technical indicators
Temperature range and accuracy
category | Code name | Graduation | Outer diameter of casing mm | Common temperature and temperature | Use temperature c | Allowable deviation | |
Measuring range C | Allowable difference | ||||||
Platinum rhodium 10- platinum | WRPK | S | Greater than or equal to 3 | One thousand and one hundred | One thousand and two hundred | 0-1200 | + 1.5 or + 1.5%t |
Nickel chromium copper nickel | WREK | E | Greater than or equal to 3 | Six hundred | Seven hundred | 0-700 | + 2.5 or + 0.75%t |
Nickel chromium nickel silicon | WRNK | K | Greater than or equal to 3 | Eight hundred | Nine hundred and fifty | 0-900 | + 2.5 or + 0.75%t |
Cu Cu Ni | WRCK | T | Greater than or equal to 3 | Three hundred and fifty | Four hundred | Less than -200 | No provision |
-40-350 | + 0.75%t | ||||||
Fe Cu Ni | WRFK | J | Greater than or equal to 3 | Five hundred | Six hundred | 0-600 | + 2.5 or + 0.75%t |
Note: "t" is the value of the measured temperature.
T grading products need to consult with our factory for ordering.
Thermal response time of armored thermocouple
When the temperature changes step by step, the time required for the thermocouple output to change to 50% of the step change is called thermal response time. It is expressed by tau 0.5.
The thermal response time of the armored thermocouple is not greater than that of the following table:
Thermal response time 0.5S | Shell type | Insulation type |
Casing diameter (mm) | ||
Two | Zero point four | Zero point five |
Three | Zero point six | One point two |
Four | Zero point eight | Two point five |
Five | One point two | Four |
Six | Two | Six |
Eight | Four | Eight |
