Electric Actuator (SPL201-SPL325)

PSL-type intelligent linear electric actuator(as shown on figure 1) is one of the executive unit products of DDZ series packaged electronic instruments. It is the executing and adjusting mechanism in the measuring and control system of industrial process with its electric adjusting valve formed by actuator and adjusting valve body. It receives 4-20mA standard signal, adopts permanent magnet synchronous motor as driven motor while being powered by 220VAC single-phase power supply. It is a kind of intelligent instrument innovative in science and technology while combining MCU digital control circuit and mechanical transmission and it is a high-tech product of mechanical-electrical-instrumental integration that is essentially supported by national industrial policy.
PSL intelligent linear electric actuator can be matched with conventional analogue instrument to form the automatic governing loop and can also be used as terminal executing element along with field bus control system of HART protocol and FF protocol. It has been widely applied in such industries as petroleum, chemical industry, metallurgy, power station, textile, food, pharmaceutics and beverage.
