Hi guys , Can someone tell me why we use heat tracing for glycol used in impulse line in level measurement? Does the state of the glycol change with the process pressure of the vessel where level is measured? Thank you

Hi guys What standard talks about installation of instruments ? Thank you

HI How to select values for end of line resistor and terminating resistor connected to fire detector loop ? Thanks

Hi Can someone share cable spec for a heat detector installed outdoor (fire and gas cable for outdoor application) . Thank you

HI How I terminate two cables in parallel in the loop. The loop consists of detector in the field, junction box, marshalling cabinet, and system cabinet. Already one cable exists, i am adding a new cable to decrease voltage drop. Thank you

HI What is the criteria for choosing 2 wire, 3 wire, or 4 wire configuration for transmitter/field device ? Your comments please Thank you

HI How can a gas detector generate nuisance high alarm due to voltage drop. What is the relation between the two? And what is the best solution for this problem ? Do we change the detector, the cable, or power supply ? Your comments please

HI When to use intrinsic safety circuits ? Is it based on hazardous areas only or there is more to it ? Thank you

Hello I have a question around equipment certification please. When to use EX d (flameproof enclosures) , and EX e (increased safety). Does it depend on the hazardous zone or sth else? Your comments please Thank you

Hello In some transformer yards, I have seen flame detectors installed for transformer fire detection, and in some yards , heat detectors are installed. Why such a difference? I was told heat detectors are more suitable. Does it mean that flame detectors is a wrong engineering decision...

Hi Want to ask about the location where to install heat detector in transformer yards..should it be installed on top of transformer or underneath ? What is the standard that specifies this one? Thank you

HI What fire detection type (flame or heat) is best for transformer fire detection? Which standard mentions this point? Your inputs please from experience Thank you

HI What fire detection type is best for transformer fire..what standard mentiones this point? Your inputs please from experience Thank you

Hi Anyone knows why they install gas detectors in gas turbine inlet air filters ? Any reference from international standards please? Thank you

HI need to rerange orifice plate differential pressure flow transmitter. Should I worry about the orifice plate capacity/parameters or I just have to look at the transmitter factory differential pressure range to make sure the new DP falls within the transmitter range. your thoughts please ...

HI Need to select junction box material that withstands high temperature (to be installed in hot area, near turbine enclosure), what would be the best JB material ? JB should also have other features e.g. rigid, durable, corrosion resistant etc. what about terminal strips/blocks inside...

Hi , I have seen in some cases cable size is difference for the same circuit, for example from transmitter to junction box is 1.5 mm and from junction box to control room it is 0.5 mm .. is this acceptable and why is that ? Thank you

Hi Is it a good idea to use level switch as part of 2oo3 voting where the other two devices are transmitters.. in this case , if the switch fails, we will not know and we will end up having two devices (2oo2) configuration.. is this correct ? Can anyone add more comment from experience on...
