Airbag timers KiTimer 2.0, airbag ignition device, robust measurement for pyrotechnic igniters / K3889B
These airbag timers serve as robust measurement and ignition devices for pyrotechnic igniters; they belong to the family Type K3889B.
- Ignition of pyrotechnic igniters
- Recording of ignition event, ignition current and voltage
- CrashLink 2 (CL2) interface
- Programmable ignition parameters
- Resistance measurement of the ignition squib
- Battery buffering
The KiTimer 2.0 is used to trigger pyrotechnic igniters in crash tests and during crash simulations on sled test rigs. The device features 16 programmable ignition channels, allowing very precise adjustment of the ignition current and pulse duration. During a test, the ignition event together with the ignition current and ignition voltage is recorded for each channel. To prevent inadvertent ignition of the airbags, a so-called block or inhibit dongle is supplied with the device. This blocks ignition of the channels until it is removed from the KiTimer 2.0. As an alternative, the USB dongle from the KiTimer 1.0 (Type K3889A) can be inserted into the host computer for further use.
