Radiation shielding - Import export

Vaisala INTERCAP® Humidity and Temperature Transmitter Series HMDW80 measure relative humidity and temperature in various building automation applications. Transmitters combine easy installation and reliable operation with a low requirement for maintenance. The versatile HMDW80 series includes transmitters for wall and duct mounting, IP65-classified transmitters for humid areas, and transmitters with a radiation shield for outdoor use. It also includes temperature-only transmitters and transmitters with an optional display. Calculated humidity parameters – dew point temperature, wet bulb temperature, and enthalpy – are also available.

Product Features: • Primary 115 VAC, 60 or 400Hz. models, 3 case sizes. • Epoxy cast to withstand shock and severe environments. • Two coil design provides balanced windings and low magnetic radiation - no electrostatic shield required. • 228 Series include four, 6-32 x 0.38 machine screw inserts for less strain on P.C. board connections.

Tungsten has a high density, which makes it convenient for ionizing radiation shielding. Despite the higher density compared to traditional and cheaper lead, tungsten shielding is less heavy with equal shielding properties, and more effective if the weight is the same. Tungsten is a very refractory and hard metal, which makes it difficult to process. Therefore, more ductile tungsten alloys with nickel, iron, copper, etc. are used. Cr 16.0%-18.0% We buy alloys of the following grades: VN/VNZh alloys (category: Tungsten 12) (W - 80 - 90% Ni - 5 - 10% Fe - 1- 3%) VD alloys (W - 70 - 80% Cu - 20 - 30%)
