Sensor/Change- Electronically Initiated Devices

A sensor used in an IED is based on an electronic device wired into a circuit board with a detonator attached. The electronic device senses a local change, through modification of, for example: temperature (up or down ), visible light intensity level (stronger or weaker), magnetic force, pressure, invisible light intensity level (infra-red or ultra-violet), x-ray beam intensity, proximity, sound intensity level, humidity change, smoke particles, etc. Typically the sensors that respond to the changes undergo an internal change in electrical resistance—that ability to allow a certain amount of electrical current to pass. The attached circuitry then acts on the change in resistance, sending an electrical impulse to a relay, transistor, silicon controlled rectifier, and ultimately to an electric detonator. Securesearch manufactures circuitry used in training aids that demonstrate how these sensors work in IEDs.

Sensor/Change- Electronically Initiated Devices

PASSIVE INFRA-RED SENSOR IED
Order Sku: ITA-112A
Designed to initiate a detonator when the room being monitored is entered. This device senses heat movements, changes.

Price: Request Quote

PROXIMITY/TOUCH INITIATED
Order Sku: ITA-127A
Proximity/Touch initiated. Uses dual oscillator, very sensitively balanced magnetic field-emitted insulated wire.

SMOKE / DUST SENSITIVE IED
Order Sku: ITA-108
In operation, smoke or dust particles blown into the sensing chamber, cause a change in resistance. This is then translated by circuitry to output a detonating signal.
