automation/control engineers

[rdpzycho]

tama yung sa Universities. yun lagi ang katwiran ng mga Universities. dahil hindi mo rin naman daw gagamitin halos yung tinuturo sayo at foundation lang siya. pero hindi maganda kaya laging andaming kailangan ituro sa work. kaya marami talagang technician na mas mahusay sa ibang engineer dahil nakakahawak na talaga sila ng gamit, samantalang yung engineer teorya pa lang ang alam.

maganda siguro na mapalitan na rin ng konti ang curriculum ng mga estudyante. magkaroon na ng OJT talaga na halos katulad nung sa mga Nursing.

di ko magamit dito kasi wala akong matisod na transmitter eh.  

baka meron ka dyan... peram mo muna sakin...

@ sir SPO2
  wala pa sa ngayon sir, puro bago pa kasi instrumento namin d2... pag meron timbrehan kita heheh... sayang yung 375 mo sana ako na lang nakakuha heheh... ayaw mo pa mag divert sa fieldbus sir, yung mga rosemount nakakita na ako ng mga fieldbus type nilang transmitter, pero for sure mas mahal sa yokogawa yun... anung system ang hawak nyo dyan? ndi pa kasi ako naka-experience ng Foxboro system eh, puro yokogawa na kasi nga nakuha na nila yung market malaki kasi kamurahan kumpara sa ibang system ng DCS...

DCS at triconex din ang system dun sa dati kong plant.

wala pa kong experience sa fieldbus. pero merong ilang instrumento dun sa dating plant na ganun. More on SDV at MOV ang naging work ko dun. Commissioning and testing. Sa mga transmitter naman eh maganda kong nakita dun eh yung SAAB. Para sa level ng mga tangke. Ibang klase din yun eh...

san ka ba ngayon? local or abroad

[rov1976]

d2 ako sa abroad ngyon sir sa SABIC instrument maintenance department, commissioning na din ng planta namin siguro sa oct. ayus din actually d2 na din ako na-expose ng husto sa instrumentation. Medyo iba nga ang background ko kasi sa semicon ako galing mga 11 yrs ako dun, then pagdating ko d2 last yr heheh ibang-iba, buti na lang medyo nakapagbasa-basa sa internet bago mag-apply, pero kung tutuusin mas madali d2 sa petrochem kasi walang board level repair... hopefully may masira ngang instrumento para may mapag-laruan naman heheh...

para dun sa gustong mag-trabaho sa petrochem or oil&gas...
ang madugo lang d2 sobrang init and kapag medyo careless mag-troubleshoot eh malamang ma-shutdown mo planta w/c is unacceptable malamang pauwiin ka nun.. heheh tama ba sir SPO2?

I'd like to point out that most often it is also our obligation as students to learn anything related to our planned career path and not only what is taught to us in school. "universities are focusing only on the theories and vocational schools are focusing on hands-on technical skills" because it is profitable for them. before complaining about it we should instead note that wala po talagang spoon-feeding program sa engineering hehehe . hindi talaga ituturo lahat, bahala na tayong pag-aralan iba. actually ang ginawa talaga ng school natin ay i-train tayo to be efficient learners.

kaya hindi excuse kung walang alam yung engineer sa technical at vice versa wala ring excuse kung walang alam yung technician sa theory..
in reality, we should not set the boundary of learning between the technical and theoretical field. kailangan talaga natin mag-crossover, we need to have a good grasp on the real world because we are not always relying on ideal figures. at ganun din sa mga kasama nating technians siyempre.

being an engineer is not a privilege, it is a life time burden (or shall we say responsibility) of having to continuously learn more and more.
the higher we go up in our career ladders, the heavier is our responsibility.

and we have this very nice forum to help us on and some very good guys to emulate;D

correct ka dyan.... sa russia ang destination ku ngayon. petrochem din... more on commissioning lang din ang trabaho... sobrang lamig naman dun.... hehehe... magkabaligtad tayo....

dumaan din kasi sa similar problem ang US noong 1980's (sa Industry, according to some Automation books). nagulat sila sa biglang pag-angat ng competing nations nila. they find out what they lack, link between the industry and the academe. ang problem kasi, tinuruan na sa University tapos mas matagal pang tuturuan sa Workplace (if Astec would have offered their Power Electronics course sa graduating student hindi na sana sila magtuturo pa ng 1 semester ata after ng graduation). they approximated that they were few years behind the competition dahil dito. kaya ngayon yung top Engineering Universities nila sobrang hands on na. marami na ring students ang double degree sa simula pa lang.

dito dahil ganun na ang turo ang Universities, agree ako na dapat tayo na ang magkusang mag-aral.

super agree ako dito... maraming engineering graduates ang hindi na nag-aaral pa para matuto... dahil isa sa mga reason nila is tapos na ang paghihirap nila sa pag-aaral... marami akong kasamang ganito... yung kulang ang motivation and initiative to learn...

tama po. ganun na nga nangyari nung nagboom ang electronics dito sa asia. dun na-realize ng us to make something profitable out of it..
biglang pinauso ang outsourcing para pakinabangan ang low cost of labor sa asia. tinutukan na lng ang ibang mas profitable ventures.

one short-term solution is for our schools to mold its curriculum to the specific needs of this companies.. for this kailangan talaga may collaboration yung industry at academe. critics would say na parang factory na ng "industrial zombies" ang mga schools natin including the "universities".. its ok for our vocational schools to do this to address the large demand for skilled labor..

but for long term solutions the universities should not succumb totally to the present labor trend to avoid redefining entirely the definition of "university" which is being an institution of higher learning and research..

In a somewhat more theoretical vein, the late Bill Readings contends in his 1995 study The University in Ruins that the university around the world has been hopelessly commodified by globalization and the bureaucratic non-value of "excellence." His view is that the university will continue to linger on as an increasingly consumerist, ruined institution until or unless society is able to conceive of advanced education in transnational ways that can move beyond both the national subject and the corporate enterprise.

heheh... intay ka lang sir darating din yung pagkakataon mo... 

[rov1976]

post uli ako ng mga photo para magka-idea kayu kung anu-anung mga instrumento makikita sa planta, puro fieldbus na ang mga instrumento na 'to research nyo na lang kung paano i-wire sa cloosed loop yung fieldbus type na instrument... or pag may time mag-post din ako ng sample from field to marshalling cabinet hanggang system cabinet and vise versa... take note kasama sa interview ng employer yan, huwag lang kayu matatapat sa pinoy na mag-interview kung ndi lagot heheh... last time sa pinoy ako natapat dami tanung heheh buti nakalusot... ayaw pa patalo heheh... 

eto na po...

yokogawa temperature transmitter

RTD probe Dual element

yokogawa pressure transmitter

yokogawa differential transmitter

yokogawa level transmitter


enjoy na lang mga sir... sana makatulong... 

[danny]

thanks for posting. even though malayo ito sa field ko,
I am enjoying looking what's inside your plant.
Very interesting
pogi point for u

[Tambay_7]

gusto ko matutunan yang fieldbus. paano ba magkakaroon ng exposure jan?

Bro salamat sa mga link.... magandang pag aralan to...



br

[ahlburuto]

yung exposure siguro sir baka sa mismong planta mo na ma-experience, kasi satin walang training facilities para sa fieldbus technology and applications, yun ang hindi magandang istorya... base sa experience ko nung nagsisimula pa lang akong mag-apply, naghanap ako ng mga articles tungkol sa instrumentation and controls, katulad ng flow/temperature/levels/pressures etc... then dun ko na din nalaman yung mga brand ng instruments na ginagamit like siemens, abb, yokogawa, micromotion, rosemount, emerson cntrols, saab etc... yun nga lang mahabang proseso pero kelangan maging wide reader ka, kasi yun lang ang paraan para matutunan yung instrumentation and controls, well puwede din mag-enroll sa meralco foundation or sa batangas yata may university dun na nag-tuturo ng instrumentation pero wala pa din silang fieldbus, sa pagkaka-alam ko ang gamit nila sa pinas eh yung conventional pa yung may I/P na tinatawag current-to-pressure or yung 4-20ma signal, hanggang ngayon ginagamit pa din naman sa planta pero HART technology na ang tawag ngayon imbedded na yung data & information sa FSK papuntang instrumento or sa system...

yung last project ko eh hart din ang ginamit. 4-20ma. mga transmitter nila eh halos ganun lahat.
