The Sky Curtain Target Introduction

The Sky Curtain Target is a new style region interception devices for speed measuring, it is mainly used to measure the speed of flying objects more than 3 millimeters in diameter, flying at speeds 10 to 3000 meters/ second, flying with an angle of ±45 degree. As based on the principle of photoelectric, it needs no material restriction on flying objects, no more needs to magnetizing the pills and so on complicated procedures .

At using, please put the seat connector of Sky Curtain Target at an angle which can be adjusted to parallel the location of the ballistic trajectory to be tested. When the pills flying over it, I target and II target outputs the start and stop signals respectively(CMOS level, 11V/100μS), measuring the time interval “ T ” of the pills flying over the interception by electronic instrument, flying speed is as V=S/T, S is the distance between the two targets, so, we can get the speed value of the pills by calculation.

In order to improve the anti-jamming capability, the sensitivity can be set 3 sub-file according with the object size.

The Sky curtain Target can measure the artillery shells flying parallel to the ground and also can measure the artillery shells flying with an elevation. 

Performance Specification：

1. Measurement sensitivity to distinguish：> 3  mm caliber

2. Speed range：<10-3000 m/s

3. Speed accuracy：3/1000

4. Gun fire frequency：6000 shells/min

5. Effective measurement distance：100-20000 mm (Detection lens to ballistic spacing )

6. Power supply：Single-phase  AC 200-240V  < 20 W.

The Light Curtain Target Introduction

The light curtain target is also a new type of region interception devices for speed measuring, It makes a very narrow slit light screen orthotropic that is at the direction of Flight trajectory，when the flying objects which is 2mm or more and speed at 10 ~ 3000meters/second pass through it, it will generate a test signal, in room or out of room, this kind of measure need not  any auxiliary light source. Since it is based on the optical principle, so there is no material restrictions on the flying objects, and no more needs to magnetized projectile or other complicated procedures. For heterotypic shells can also select warheads or bombs tail as a start point. In order to improve anti-interference ability, the sensitivity can set as 0-4 class in accordance with the object size to be measured.

The light curtain target can only measure the Initial velocity of shells which flies parallel to the surface of the earth.

Performance Specification：

1. Measurement sensitivity to distinguish：> 2  mm caliber

2. Speed range：<10-3000 m/s

3. Gun fire frequency：6000 shells/min

4. Effective measurement area：340X540mm

5. Start selection：warhead / bomb tail

6. Power supply：Single-phase  AC 200-240V  < 20 W.

7. Output signals: 11V

Speed meter Introduction

HG202C一4 type two channel Speed meter  retained the advantages of HG-202C-3 type, improve its inadequacies, and we develop this new type of intelligent speed meter on the basis of concentrating all the advantages of Speed meter in China. Its features are as follows:

⑴  This machine is reliable. Adopt the new single-chip microcomputer to improve the integration and reduce the component. Applying the single-chip microcomputer on this machine are the original.

⑵  This machine is simple, date-processing intelligence, users do not need to study computer language, Just press the action button can carry out data processing.

⑶  This machine can amended air resistance automatically while measuring the speed of Vx. Chamber volume amending；Detonator temperature amending；Bomb weight amending；Fire angle amending. Fire frequency and fire time interval etc can be firmed in the machine to all the standard shells or to the shells that the ballistic parameter being put forwarded by user. The ballistic parameters to the non-standard shells, can be entered to the machine conveniently by the “double-function key”.

⑷   This machine use non-polar circuit, be adapt to the region interception devices like coil target, on-off target, and sky curtain target etc. Can also start or stop the speed meter by entering pulse signal directly.

⑸   This machine has a data memory function, can store 102 data. In the case of power off suddenly, the data measured can not lose. The data can be stored in the machine long time until you clear it.

⑹   The local clock for the two-way sharing, divided into 0.1μs、1μs、10μs、0.1 ms、10ms five block, Count the capacity of each road are 655,359.

⑺   The door closure time of local road 1 and road 2 can select from 0.01ms~99.99ms

respectively as closure 1 or closure 2 and can be firmed in the machine at beginning. If you

think the door closure time that is firmed in the machine at origin is not appropriate ,you can

enter the door closure time as closure 1 or closure 2 that is fit for this test by  some  buttonsconveniently.

⑻   This machine has the strong remove function. It can erase any one data measured, also can erase the t1 or t2 that is in one data.

⑼   The machine consumes very little power and total power consumption is only 3.8W( not including printer)

⑽  The testing data can be read out by the 6 digital tube clearly 6 digital tube

⑾  Small size, light weight, volume 840 (wide) × 840 (deep) × 100 (high) mm ³, weight 3.85kg
