TiNi’s Thermal Trigger may be used in a variety of fire safety applications. The enabling technology is the use of TiNi’s SCSMA (Single Crystal Shape Memory Alloy) material which makes it possible to set the trigger temperature at much higher values than is possible with commercially available SMAs.
TiNi Thermal Trigger offers the following advantages:
NEA (Non-Explosive Actuators) – As with all TiNi products, the Thermal Trigger is non-pyrotechnic and field reset-able with a minimum qualified life of 50 cycles.
High Trigger Temperature – The SCSMA material allows the trigger temperature to be set far above commercially available SMA material’s which are limited to approximately 100 °C. By contrast, TiNi Aerospace’s Thermal Trigger may be set to actuate at a temperature of up to 200 °C.
Field Reset-able and Reliable – The Thermal Trigger is resettable by simply replacing the severed bolt element after each actuation cycle. This allows confirmation of the Trigger Temperature for each and every unit manufactured. .
No Stored Energy – The Thermal Trigger does not have any stored energy which is critical in applications where it is absolutely necessary to protect against the possibility of inadvertent release.
High Output Force – Output force and stroke is sufficiently strong to be able to initiate a pyrotechnic charge in fail safe applications.
