Product Details

Armored thermal resistance（RTD PT100 Sensor）adopts the characteristics of a substance that changes in temperature and its resistance changes to measure temperature. When the resistance value changes, the working instrument will display the temperature value corresponding to the resistance value. Armored thermal resistance is a kind of temperature sensor. It is smaller in diameter than assembled thermal resistance, easy to bend, and has good shock resistance. It is suitable for installation in places where assembled thermal resistance cannot be installed. Armored thermal resistance adopts imported thermal resistance temperature measuring element. Therefore, it has the advantages of accuracy, sensitivity, fast thermal response time, stable quality and long service life.

● Short thermal response time, reducing dynamic errors;

● Small diameter (3, 4, 5, 6, 8mm) length is not limited;

● High measurement accuracy;

● High-precision chip, reliable and stable performance

● Smaller in diameter than assembled thermal resistance,easy to bend, better shock resistance.

Advantages of Sheathed Temperature Sensor

● Resistant to vibration and shock: The metal sheath and cable protect the conductors from shock and vibration, preventing breakage and making sheathed thermocouples highly resistant to mechanical stresses.

● Resistant to corrosion and aggressive media: 316 stainless steel has good resistance against aggressive media and the vapor and flue gases in chemical media. The corrosion-resistant properties of Alloy 600 make it particularly well suited for thermocouples that have to deal with high temperatures. It also withstands cracking and pitting in media that contains chlorine, and corrosion produced by hydrogen chloride or ammonia in aqueous solutions.

● Small and flexible：The protective metal sheath allows for finer conductors and a more compact design than those of unsheathed thermocouples. Sheathed thermocouples' diameter can be as small as 0.5 mm without compromising the integrity of the instrument. The metal sheath also gives flexibility, which allows bending without damaging the sensing element. As such, sheathed thermocouples are particularly useful for temperature measurement in small spaces and in tight corners.

● Conductivity and high temperature limits: The metal sheath tolerates very high air temperatures: up to 850°C (1,562°F) for 316 stainless steel, and up to 1,200°C (2,192°F) for Alloy 600 – depending on thermocouple type. The sheath also provides better heat conduction than unsheathed thermocouples, thereby decreasing thermal lag time and resulting in even faster responses。
