'Metron' Actuators are highly reliable, compact single shot devices which can push, pull, cut or shear with a power to weight ratio in excess of 10,000:1. They operate within milliseconds of receiving the appropriate electrical impulse, a rate which is almost impossible to achieve with a mechanical source of energy.
The short reaction times and high power to weight ratios are achieved by sophisticated pyrotechniques developed by Chemring Energetics UK Ltd over many years. Within the metal body of each device, rapid expansion of hot combustion products generates very high pressures which are used to do mechanical work, e.g. drive a piston or cutter.
Electric initiation is achieved by the use of specifically developed fuseheads which are sufficiently varied to offer a range of sensitivities. To take into account the wide range of uses to which these devices are subjected, ‘Metron’ actuators may be supplied with different fuseheads e.g. when power supplies are limited a fusehead with high sensitivity may be required whereas a low sensitivity may be preferred under circumstances where spurious electric current can be induced.
Their ability to rapidly convert small electric signals into high mechanical work output, their compact size, high reliability and good environmental resistance make ‘Metron’ actuators ideal for automatic or remote controlled applications in Fire Protection, Security, Defence and Aerospace industries.
'Metron' Actuators ideal for remote controlled applications such as
- Puncturing containers eg. to release high pressure gas
- Pushing mechanical loads eg. opening valves
- Locking a device to prevent rotary or linear motion
- Releasing a device to enable rotary or linear motion
- Operating a sprinkler bulb
- Operating a switch or delay
- Arming/disarming a weapon SAU
- Cutting wires or small bolts
In addition to BS ISO EN 9001-2000 quality registration, 'Metron' Actuators are also registered by LPC and UL for use in Fire Engineering applications
