The viewing devices with windows electric heating are prismatic periscopic ones and are designed for observation of the terrain from an object at temperatures of +50oС to -50oС. Electric heating stops sweating and icing on the device windows within a temperature range of 30 ± 15oC by means of RTC temperature regulator. Power supply operates off the d.c. supply line of 27V voltage. The devices TNP4A06 and TNPO-160 ensure: - safe observation when hitting a bullet on a window; - tightness of the device and an object at hydrostatic pressure of 0.7 atm. | Specifications | Viewing devices with windows electric heating | | TNPO-170A | TNPO-115 | TNPO-160 | TNP-350B | TNPO-168V | BMO-190B | TNPO-260 | TNP4E06 | | Total range-of-vision in vertical plane | 23' | 33' | 28' | 10.5o | 31o | 20' | 25o | 30' | | Upper range-of-vision angle in vertical plane | 12' | 11' | 12o | 5o | 15o | 9' | 12o | 10' | | Lower range-of-vision angle in vertical plane | 11o | 22o | 16* | 5.5' | 16' | 11o | 13o | 20o | | Field-of-view angle in vertical plane | 6.5o | 6.5' | 5' | 4' | 6o | 5.5o | 6o | 6o | | Total range-of-vision in horizontal plane | 94o | 110' | 78' | 42o | 138' | 69o | 76o | 74' | | Field-of-view angle in horizontal plane | 44' | 44o | 36' | 26o | 58' | 34' | 36o | 36o | | Binocular field-of-view angle | 15o | 12o | 12' | 8o | 32o | 10' | 14' | 8.5o | | Deflection angle of normal beam in vertical plane | - | - | - | - | - | - | - | 20o | | Transmission factor (%) | 44 | 44 | 44 | 50 | 45 | 43 | 42 | 44 | | Periscopic power (mm) | 162 | 115 | 160 | 350 | 168 | 190 | 260 | 165 | | Overall dimensions (mm) | length | 163 | 142 | 151.2 | 151 | 267 | 156 | 181 | 140 | | width | 62 | 57 | 97 | 70 | 84 | 48.5 | 75 | 100 | | height | 230 | 178 | 238 | 405 | 257 | 319 | 356 | 230 | | Weight (kg) | 2.9 | 2.3 | 3.4 | 5.68 | 7.25 | 3.4 | 7.5 | 3.2 | | Power consumption (W) | 117 | 53 | 85 | 8.5 | 184 | 110 | 130 | 85 | | Location size (mm) | 151x44 | 133.5x42 | 140x50 | 151x44 | 250x50 | 151x43 | 170x58 | 122x48 |
