Hi JRW261,
for gas analysers try a company called erwin sick, their website is www.sick.com. They have a wide range of gas analyitical equipment ranging from in-situ measurement to extraction measurement.The units are all in one.
On our site we have the mcs100 models (five of them).They've...
Gordon,
The proxy's purely look at the shaft movement but when the steam turbine is running, the bearing shell is also moving. So, the accelerometers are compensating for this bearing shell movement which in turn corrects the proxy signal through some math that is used in the software,thus...
Hi, I work on a relatively new alstom power plant and our 250MW steam turbines do utilise accelerometers for shaft supervision.
These are mounted on top/in the same plane as the eddy/proxy probes on the journal bearing housings.This is used to provide an absolute value, not just shaft relative.
Thanks to all of you, some really valuable post.
Think i'm going to go for the OU option as i'm still young and still have lots to learn! and i've got the time to put max effort in.
Xnuke, i totally agree and have seen those points myself and engineers do get more respect from their team if...
I don't seem to have made my question clear.
On site we have a maintenance management system (PowerMaint) which creates jobs based on a weekly cycle. So if an instrument is due for calibration a work order is automatically generated. From a calibration management point of view we are ok...
No it's nothing to do with that.It's just that it will take the common sense factor out of calibrations.i.e.a druck telling you what you have to cal next and what you should be applying etc.
We already have a cal database that we designed ourselves and works perfectly but management want to...
Hi Forum, I'm an instrument and control tech in the uk working at a power station in Lincolnshire and the company have offered to sponsor me for a degree , preferably in measurement and control but i'm really,really struggling to find a suitable course that offers part-time study. The closest...
Hi forum. Has anyone had any experience with calibration management software?
We are thinking of buying a system that beamex make. The engineers are all for it but the maintenance tech's are weary.
We don't like the idea of test equipment telling you what cal to do next or what the input /...

Is the -10V the 'gap' voltage which tells you that the sensor is the correct distance from the object? The -10V should be the mid-range of the sensor.i.e. 0 to -20V and your setting it to -10V. This would make sense because if the object moves towards or away from the sensor it...
Hi,
For a zone 2 area there aren't any requirements for certification etc for tc's and rtd's.
However, if you are installing an amplifier in the loop then it may be best to mount the amplifier outside the zone or if that's not possible then install a barrier.
Quite a confusing quote as pneumatic valves can be direct or reverse acting.
From this quote i would say that direct acting is a valve that's hydraulic/electrical/mechanically actuated.
It sounds to me that the rtd is 2 wire which means there is no compensation lead. The way to verify this would be to measure the resistance between cores.
Only 3/4 wire setups have compensating leads.
Where i work we use rtd's and thermocouples and input these to SMART temp.transmitters, this...
I've used radar types successfully for this sort of application before and you can actually set up the instrument with the agitator running and enable the instrument to 'ignore' the agitator movement (if this is required). Hope this helps
