2 Metron Actuators 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 designs 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 fuzeheads 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 fuzeheads e.g. when power supplies are limited a fuzehead 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 electrical 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. Nomenclature Each device in the Metron Actuators range is uniquely defined by a standard nomenclature. Actuators are grouped into five main types: Nomenclature Piston Protractors Retractors Gas Generators Guillotines Igniters DR2000 series DR3000 series DR4000 series DR5000 series DR9000 series Within each of these series a range of cable finishes may be supplied. The cable finish is defined by C(x) where x is a number corresponding to the type of finish e.g. DR2003/C1 corresponds to a piston protractor defined as DR2003 with cable finish C1. The electrical characteristics are defined by the DR number within each series e.g. DR2003 uniquely determines the physical dimensions and the electrical characteristics of that protractor. Numerous types of existing cable finishes and harnesses can be supplied with the actuators. Bespoke cable finishes can also be added to customer s requirements. Please contact the sales department for more information.

(2) The fusehead may be desensitised by being subjected to currents between the maximum recommended monitoring test current and the No Fire (inclusive) and is not guaranteed to fire afterwards. Operating Characteristics Single Actuator Firing The required battery or power supply voltage may be calculated from the product of the recommended firing current (I) for the device in question and the total circuit resistance (R) i.e. V = IR Multiple Actuator Firing When more than one actuator is to be fired in a circuit, Chemring Energetics UK recommend series firing as being the simplest method. In multiple firing circuits all actuators must be of the same electrical sensitivity (eg Type 1). On no account must devices of different manufacture or electrical sensitivity be mixed in the same circuit. Where parallel firing is considered necessary, extreme care must be taken to ensure balanced resistances and the possibility of the actuator circuit remaining intact after firing must be borne in mind. Insulation Before firing, an insulation of not less than 100 megaohms at 100 V DC exists between the shunted leads and the body of the device. Electrostatic Sensitivity Metron Actuators will withstand a discharge of 300pf at 5kV minimum between the shunted leads and the body of the device. Metron Actuators can be designed to withstand higher levels of electrical sensitivity if required. Device Function Time The function times of the actuators vary with current applied and load to be moved. Typical values may be milliseconds. Hazardous Atmospheres 1. Incendivity tests in 9% methane/ air mixtures have been carried out in accordance with the M and Q Testing Memorandum No. 13 published by the UK Health and Safety Executive. The tests gave no ignition in 200 firings of Metron protractors. 2. Metron protractors have been fired by an I.S. low voltage electrical supply in an explosive gas mixture. The test mixture was 40% hydrogen, 20% oxygen and 40% nitrogen, as described in Appendix1, of BASEEFA. Certification Standard SFA 3007:1981. The tests (conducted in the gas mixture giving the most severe conditions specified in accepted standards for apparatus intended to be used in hydrogen/ air mixtures) gave no ignitions in 200 firings.

4 Metron Actuators in Series The current needed to operate a number of actuators in series is greater than that required for a single device. The reasons for this may be explained in the following manner. Consider a series of Metron Actuators to which a uniform direct current is suddenly applied. Before any one device can operate the fuzehead must be traversed by the current for a certain minimum period of time, usually the order of a few milliseconds, during which the wire heats up to the ignition temperature of the pyrotechnic mixture. The minimum time is termed the excitation time. In practice, the excitation time will vary slightly from one actuator to another because of inevitable small manufacturing variations. After the fuzehead has received this minimum dosage of current there will normally be a further lapse before the ignition has spread throughout the fuzehead and broken the electric circuit. The time from the first application of current to the rupture of the circuit is referred to as the lag time. For all Metron Actuators, in series, in an electric circuit to operate successfully the shortest lag time of any of them must exceed the longest excitation time of any of them. In other words, every one of the devices must receive the full quota of electric energy to cause its ignition before any single one of them has completed its lag time and broken the circuit. The operating characteristics of Metron Actuators can be represented on a diagram as in Figure 1. Here, the line A P B shows the relationship between current and lag time, while CPD shows the corresponding relationship between current and maximum excitation time. Now consider the current i. From the curve it will be seen that the most rapid actuator will break the circuit in T 3 milliseconds, where as the least sensitive actuator requires the current to flow for at least T 4 milliseconds to enable it to operate. At a higher current i 2, however, the excitation time T 1 is less than time T 2 which is allowed by the most rapid actuator and hence the least sensitive actuator in the circuit will have ample time to receive its full quota of current before the circuit is broken at T 2. Somewhere between the two current values i 1 and i 2 corresponding to the cross-over point P, there is a value i s which will be the minimum operating current for the series considered. In practice, i s is always higher than the minimum operating current i o for a single actuator of the same type. When more than one actuator is to be fired in a circuit, Chemring Energetics UK recommends series firing as being the simplest method. In a multiple firing circuit all actuators must be of the same electrical sensitivity. On no account must devices of different manufacture or electrical sensitivity be mixed in the same circuit. When parallel firing is considered necessary, extreme care must be taken to ensure balanced resistances and the possibility of the actuator circuit remaining intact after firing must be kept in mind. The principle of series and parallel firing of actuators and detonators is well established.
