HI Folks

I know exactly what I want it to do - just don't know what it's called
(so having trouble finding it online)

For the new kiln - it'd be interesting to have a simple recorder that
displays 'heating hours' per firing cycle (i.e. the actual time that the
heating elements have been powered on) - as this would give a measure of
the actual electricity costs / usage.

So - I'm imagining a little (Chinese!) pcb with 7-segment led displays,
that counts the total number of minutes an input has been 'closed'.
Also to have a 'Reset' switch or input...

Anybody seen one of these (I've been scouring eBay..) and can point me
in the right direction, please ?

Thanks
Adrian

How about an old fashioned mains mechanical clock?

There are plenty of plug in devices that record the power

Generally called power meters in ebay etc.

Useful to include the word consumption in the search terms

Easier to just wire a consumption meter in. You have
to wire in timer anyway and those are harder to find.

No. They are usually the multiple dial types. You could keep a record of

Not normally but is it so difficult to subtract the start reading
from the end reading? It'll also be measuring the actual energy used
rather than some calculated value based on two assumed values (actual
mains voltage and power drawn by the elements).

eBay seems to have many meters available for £10 - £20. Even DIN rail
mount meters are about.

OK - yes - simple subtraction is possible grin
Thinking about it overnight, the control relays on the homwbrew kiln
controller have spare voltage-free contacts available (closing when the
elements are energised) - possibly the quickest way to use these is a
simple pic board that sees the closed contacts and increments a timer.
I've got a prototyping board kicking about here somewhere...

The background to all of this is that the new kiln has ceramic fibre
insulation, while the old one had conventional firebricks.
(Small thermal mass to heat up, vs big thermal mass that's slow to cool
down)

The same model of controller is used on both kilns - and it seems that
the one on the ceramic kiln is cycling more frequently than the one on
the brick kiln. At the end of the firing schedule, the controller
displays 'elapsed program time' - but not 'actual element firing time' -
so I was curious to know the power consumption of the new kiln over the
whole cycle.

Doesn't need to be ultra-accurate - and I'd rather not wrestle with that
darn 6mm2 cable again to connect anything 'inline'..

Thanks

I was going to say that. Many of these modules were about a few years ago,
but seem not to be now. One was a bit like a tape counter that went one
digit every minute and the slowest one was days. It had a reset button. No
idea where is was used, but not seen any for sale recently.
I often think that technology has replaced things that were simple and
useful with stuff that is software controlled and hard to use for anything
other than what it was made for.

It's a possibility, but it'd mean breaking into the 6mm2 cable that I

As I said somewhere else, there's a pair of volt-free contacts in the

HI Philip
I've got a similar device here - but I've been so tidy with the cabling
that there's not really room to squeeze the clamp over one conductor...
Thanks for looking, though...

All that's really needed is a minute / hour timer that's stopped /
started by an external switch.
I've just remembered that I've got some analogue battery clocks modules
in the workshop -
I guess one of those would do at a pinch - simply wire my volt-free
relay contacts inline with the battery.. - manually set the hands to
'midnight' to reset the clock...

Not pretty - but I guess it'll do the job (quickly!) g

For the new kiln - it'd be interesting to have a simple recorder that

NO Reset function!

YES it has.

Thanks for the link.
It does make reference to a minimum reset time (a pulse, presumably).
Low volt supply isn't a problem - got that already in the control box.

On a side issue - which clown (re)designed the CPC website ?
On that page, there's links to 'Further Information' and 'Catalogue page'.

The catalogue page link takes you to a page in their whizzy 'flip the
pages over with your mouse gosh that's cool' online catalogue - but the
page they link to is full of wall-mount boxes and enclosures - no
mention of hours meters.

The further info link takes you to a page on Curtis Digital Hours Meters
- which doesn't include this pcb-mount model.

How the **** do they expect to sell anything ??

Oddly - feeding "pcb mount hour meter" into eBay shows up a UK-based
supplier selling the item for more money that CPC - now that's got to be
a first! grin

No info on how / what the reset function might be - though an online
copy of the datasheet says that Reset is 'optional on 701'...

Thanks - food for thought

Same item on the Farnell site gives better datasheet
http://uk.farnell.com/curtis-instrum...dule/dp/516284
Just use a momentary pushbutton switch for the reset.

It's called a Resettable hours run meter or Resettable hour meter.


Yep, it's as simple as that! The non-resettable type, as used on
diesel powered gensets (emergency standby or shipboard gensets), are
known simply as "Hour Meters".

They're used to facilitate periodic servicing in the same way a
vehicle's odometer is used to represent approximate engine run time
servicing intervals. In both cases there'll also be service tasks
based on time intervals for when the machinery is under-used.

For ICE powered gensets, the Hour Meter might be replaced with a more
accurate revolutions counter to determine the servicing intervals.

Although for this use, constant rpm, an Hour Meter can be just as
effective, it's when the engine might be used to drive a slightly less
powerful 50Hz generator than a 60Hz one that the revolutions counter
comes into its own (50 hour service intervals on a 60Hz genset
corresponding to 60 hours on a 50Hz genset - 108 Mega Revolutions
reading in both cases - the servicing interval would more likely be
rounded down to 100MRevs in this case).
