Detail:
Double metal thermometer is a kind of design and measurement, the low temperature field detection instrument, can be used to directly measure the temperature of liquefied gas, gas. Compared with the domestic similar products, the instrument precision grade is 1, the instrument adopts anticorrosion material, and its temperature resistance can be as high as 200, and the lowest -40. Flange type structure, double sealing ring, the anticorrosion, good waterproof performance. The protective tube is welded by automatic argon protecting tube, the weld is firm and the intergranular corrosion is small. Table read disk is an aluminum oxide printing plate, the surface is clear and beautiful. A type of axial, radial type, universal type header type selection.
Characteristic
On the spot, the temperature is easy, safe and reliable, long service life;
Various structural forms, can meet the different requirements. Victims of mercury free, easy reading, strong shock.
Protective tube for 1Gr18Ni9Ti stainless steel and molybdenum two titanium, pressure, corrosion resistance.
Core type thermometer can not stop short time maintenance or replacement of the movement.
One is the axial, radial type, 135 type, universal type, complete varieties, suitable for various on-site installation need. Parameters:
Nominal diameter: 60100150
Measurement range: -80-500
Accuracy class: (1), 1.5
Thermal response time: less than 40S
Protection level: IP55
Angle adjustment error: the angle adjustment error should not exceed 1% of its range
Return difference: the absolute value of the difference should be no greater than the basic error limit
Repeatability: the repeatability limit should be no greater than the basic error limit of the absolute value of 1/2
