Tech/Engineering - Engineering: Industrial / IR heating | | English term or phrase: burst firing | Industrial heaters and modules
Ceramic elements
... The combined masses of the element spiral and the refractory material result in a high thermal inertia compared with some infrared sources. Thus heat-up and cool-down times can be 3-4 minutes. During this time the amount of residual heat remaining after switching off the power may necessitate the element panels or modules being fitted with quick acting baffles or retraction devices to prevent damage to heat sensitive products on conveyor lines during unscheduled stoppages. On the other hand, the slow response of the elements can be exploited to smooth the on-off periods of simple pulse type lectromechanical regulators, or ***burst firing*** SCR units.
Unità SCR a ...? Ci sono molti riscontri in rete in lingua EN per "burst firing SCR" che poi può essere seguito da unit, controller, ecc.

| | sequenza di impulsi / treno di impulsi | Explanation:
Sequenza di impulsi :
Nel modo ** a sequenza di impulsi ** le onde sinusoidali vengono fornite completamente al carico. Conseguentemente è evitato il magnetismo in DC dell'alimentazione del carico. Il numero delle sinusoidi varia linearmente con il segnale di ingresso Il tempo di
ciclo e regolabile da 400ms a 60sec.
Burst Firing
In ** Burst Firing ** mode full sine waves are supplied to the load. Consequently DC magnetising of the supply transformer is avoided. The number of sine waves varies linearly with the control signal. Adjustable cycle times from 400 ms to 60 sec.

"BURST
Con il termine **burst** viene indicata una **successione di impulsi** di breve durata e con basso contenuto energetico."

"Al terminale "Trigger Pulse Input" dobbiamo invece applicare un impulso positivo di durata pari 10uS per poter generare un **treno di impulsi** ad ultrasuoni **(burs** verso l'ostacolo da rilevare.
