Hello,

Looking for calibrator with following specs:

should have Source feature
1) RTD
2) TC

mV: 0-10V
mA: 0-20/40mA

also suggest If any OEM

& any reliable & economical models.
threephase:
If I am reading your requirements correctly, it is the one to be able to source up to 40mA that is going to put you into a world of hurt. This is an unusual requirement and only comes with the more serious industrial apparatus.

There is the Time 1090 that can source up to 80mA. Then make good reliable test apparatus in my experience, but they tend to have an old, clunky look and feel to them and are not to everyone's taste.

The other I am familiar with is from Beamex, now the MC6. They are used on many of our plants and have a good reputation, you will be talking serious money though, as it is a complete calibration solution.

Those are two I am familiar with, another couple I have found that seem to offer the functionality are;

MC50.2, MC75.2 or EC25, all from Sika. I do not know anything about them. They seem to offer similar functionality to the Time unit, but are slightly higher in price.

The final one is the PIE850, again I know nothing about them. In my country they seem to be between the Time and Beamex units in terms of price, but similar functionality to Time.

If you don't need to source 40mA and only need to measure, then you have a lot more options open to you that can only source up to 20mA/24mA.

Kind regards.

Not the cheapest for sure  :)

Just recently I got myself an "el-cheapo" calibrator but was quite amazed of its accuracy. It's the BrightWin (manufacturer?) LB02.

Build quality is more than acceptable and accuracy-wise it meets and mostly surpasses its specs by quite some margin. It's enclosed in an ultra-strong casing and comes in a nice semi-rigid box with a zipper. The probe wires are nothing to phone home about but for a calibrator, I anyway prefer just a set of banana cables with alligator clips at the other ends...

The compact size and the operation with an integral USB-chargable LiPo battery makes the instrument ideal for field applications... It really makes the life of an EE (or physicist that is...  ;) ) a lot easier. The user interface is something you've got to get used to but once familiar, it's okay-ish. I guess that's the trade-in for the small form factor of the instrument.

Please find attached a photo of the PCB inside the unit.

Cheers,
Thomas


Edit: Typos
JtroTechAB:
Surely this model BRT LB02 falls in budget. And the reviews are also good.

any source explaining the working of this model in detail would be more helpful.
In order to assess its performance.

and source for buying it for fast delivery and from cheaper shipping point of view.

Thanks for the advice. Also further any other model suggestions are also welcome.
