Sell German JUMO temperature sensor 404753/004-480-405

The German JUMO temperature sensor 404753/004-480-405-571 can operate at a maximum pressure of 20 bar. In order to install the measuring sensor, it is included in the shipment with a sensor that can operate at a maximum pressure of 20 bar. In order to install the measurement sensor, a selector switch is included in the shipment for remote control of motors in hazardous areas, in combination with a contactor or magnetic starter. They provide circuit control and/or selection. Indicator lights provide visual assurance that electrical functions are being performed in remote or local hazardous locations. No external sealing is required. Non metallic structure with metal embedded grounding grid. No need to install dedicated wires and components for grounding.

The gap between the thermocouple protection tube and the furnace wall hole should be blocked with insulation materials such as refractory mud or asbestos rope to prevent the accuracy of temperature measurement from being affected by the convection of cold and hot air due to the unfilled insulation material in the feed through or terminal grounding interval of the threaded conduit, which may cause hot overflow or cold air to invade the furnace; The cold end of the thermocouple is too close to the furnace body, causing the temperature to exceed 100 ℃; The installation of thermocouples should avoid strong magnetic and electric fields as much as possible, so thermocouples and power cables should not be installed in the same conduit to avoid interference and errors. The special grounding wire equipped in each box can provide safe grounding when removing the cover. Very suitable for use in corrosive environments.

The non-metallic casing of these control stations has a dead plug inside the socket. The plug is equipped with a power socket inside, which has recessed male contacts to reduce the risk of accidental touch. The chemical resistance of corrosion-resistant components when matched with the ordered plugs and sockets. The surface emissivity of materials depends not only on temperature and wavelength, but also on surface state, coating, and microstructure, making it difficult to measure accurately. In automated production, it is often necessary to use radiation thermometry to measure or control the surface temperature of certain objects, such as steel strip rolling temperature, roll temperature, forging temperature, and the temperature of various molten metals in smelting furnaces or crucibles in metallurgy.

In these specific situations, measuring the emissivity of an object's surface is quite difficult. For automatic measurement and control of solid surface temperature, additional mirrors can be used to form a blackbody cavity together with the measured surface. The effect of additional radiation can increase the effective radiation and effective emission coefficient of the measured surface. By using the effective emission coefficient to adjust the measured temperature through instruments, the true temperature of the measured surface can be obtained. The most typical additional reflector is a hemispherical reflector. The diffuse radiation near the center of the sphere can be reflected back to the surface by a hemispherical mirror to form additional radiation, thereby increasing the effective emission coefficient. In the formula, ε is the surface emissivity of the material, which is specifically designed for the maze path point between the lid and the body to prevent moisture and dust from entering.

Pressure resistant pipes with molded high-strength 30% glass fiber reinforced material threads. Two rows of LCD display can show two measured values or two calculated values. For strongly polluted or corrosive environments, sensors with special coatings can be used. The chemical resistance of the polymer coated sensor has been significantly improved, thereby significantly enhancing the long-term stability of the measurement transmitter, especially during the drying process.
