WZP series assembled platinum resistor
Product name: WZP series assembled platinum resistor
Number of products: 132945-290 Product model: 0 Updated: 2009.06.14 Manufacturer: Thermocouple--Shanghai Feilong Instrument Electric Co., Ltd. Product details WZP series assembled platinum resistor (Using imported platinum resistance element) Industrial platinum resistance is used as a temperature measurement transmitter. It is usually used to display, record, and adjust instrumentation to directly measure the surface temperature of liquids, vapors and gaseous media and solids in the range of -200-500 ° C in various production processes. This series of assembled platinum resistance adopts the introduction of platinum resistance elements as temperature measuring elements. Therefore, it has good electrical output performance. Display, recorder, regulator, scanner, data logger and computer provide accurate temperature change input signals. Structural principle Fabricated platinum resistance is composed of temperature sensing element, stainless steel outer protection tube, junction box and various fixed devices. There are two specifications of branch components, and two platinum resistors can simultaneously output two sets of the same resistance signal for use. Platinum resistance is a kind of temperature sensor. It uses the characteristics of platinum wire to change the temperature when the temperature changes. The stainless steel protection tube not only has anti-corrosion performance, but also has sufficient mechanical strength to ensure platinum resistance. Safe to use on all occasions. Prefabricated platinum resistance junction boxes are available in two types: splash-proof and waterproof. The installation and fixing devices include fixed threads, movable flanges, fixed installation flanges, and tapered protective tube devices with fixing bolts. Main Specifications Resistance value of thermal resistance temperature sensing element at 0 ° C (day.) Indexing number Ptl00: Class A R. = 100 + _O. 06Ω Class B Ro = 100 ± 0.12Ω Thermal response time When there is a step change in temperature, the time required for the output of the thermal resistor to change to 50% of the step change is called the thermal response time, which is expressed by T05s. Nominal pressure Generally refers to the protection tube can withstand static external pressure without rupture at normal temperature, the test pressure is generally 1.5 times the nominal pressure. In fact, the allowable nominal pressure is not only related to the protective tube material and diameter and wall thickness, but also to its structure, installation method, insertion depth, and the flow rate and type of the measured medium.
