Armored thermal RTD is an industrial temperature sensor. It is slender, flexible,easily bending and shock-resistant. The WZPK serial products of our company consistof various thermal RTD units. They are more accurate, sensitive, durable andshort-in-response-time. Sheathed thermocouple is coated with stainless steel casing, filled with high-densityoxide insulator material inside. Therefore, it has very good mechanical strength,with anti-pollution feature in abominable environments. RTD can be used tomeasure the temperature from -200~600°C, directly linked to the copper wireor other secondary instruments. Because of its excellent electrical output characteristics for the indicator, it can provide accurate data to recorder, regulator,scanners, computers and other devices.
