本文介绍引信起动计数器。该装置的发射机线圈装在炮口处的初速测量装置的下方。发射机线圈可在弹丸通过时发出数字词整信号，以便对起动弹内延期引信的计数器进行感应调整。每一数字调整信号均由双脉冲构成，而且发射机线圈能够向弹内的接收机线圈传输预定数的脉冲（例如．至少１２个双脉冲）。电子开关用于控制发射机线圈的工作。滤波装置与弹内的接收机线圈和计数器连接，以便消除由初速测量装置产生的干扰脉冲。
This article describes the fuze start counter. The transmitter coil of the device is mounted under the muzzle velocity measuring device. The transmitter coil emits a digital word when the projectile passes in order to adjust the counter of the detonation fuze within the activation projectile. Each digitally adjusted signal is composed of two pulses, and the transmitter coil is capable of transmitting a predetermined number of pulses (eg, at least 12 double pulses) to the receiver coil within the projectile. Electronic switches are used to control the transmitter coil’s operation. The filter unit is connected to the receiver coil and counter in the bomb to eliminate interference pulses generated by the rate-measuring unit.
