Electrical resistance coil operates in liquid environment (capacitor oil, kerosene, organosilicium fluid).
Acceptable resistance deviation of coils from their nominal values caused by adjustment inaccuracy at temperature of 20°C andpower not exceeding nominal:
for accuracy class 0.01 is not more than ± 0.01%;
Resistance change during the year is not more than:
for coils accuracy class 0.01 ± 0.002%;
Real resistance value change at power change from nominal to maximum acceptable in steady thermal conditions:
for coils with accuracy class 0.01 is not more than ± 0.005%;
Dimensions 110x170 mm.
Coil weight without oil is not more than 1 kg.
Mean time between failures: is at least 66000 hours for coils. Operating conditions of : ambient temperature 15 ... 30 ° C; relative humidity 80% (at 20 ° C).
If necessary we can take photos of a device from
various angles.
Technical
Documentation
In case you didn't find in technical specifications
for the device all necessary information you are interested in, feel free to
contact me. I will look through the technical documentation for the
device and I will be happy to consult you.
Also I may speak directly with the manufacturer and
find out more specific information about this product.
If some technical parameters for the device (error,
accuracy, measuring range, operating voltage and frequency) do not meet your
requirements, please, e-mail me and I will negotiate with the manufacturer
whether it is possible to deliver you a device on the desired specifications
without a cost increase and in the shortest time.
On delivering the device, electric circuit diagrams
and all technical documentation for operation, calibration and maintenance will
be supplied. Also there will be documents that testify the accuracy and
compliance with specifications.
In addition, translation of technical documentation
into the customer’s language may be discussed.
Delivery set
On delivering the device will be completely ready for
use.
There are all necessary cables, adapters, sensors and
spare parts as envisaged in technical documentation. Hence, there is no point
in purchasing any additional repair & measurement equipment.
Warranty
Warranty
of this item - 12 month.
Before sending a device, all devices are checked
whether they comply with all technical specifications.
Highly qualified metrology engineers carry out the
check-up of every instrument at a specialized laboratory and with the help of
master gages.
If necessary, we can send you photos or video with the
check-up process.
I ship only fully working devices complying with all
parameters.
The warranty for this device is 1 year from the date
of shipment from my warehouse.
Within
1 year term I will provide the repair of the device for free in case of
manufacturing defect or when the technical parameters do not comply with
technical documentation. You will have to pay only for delivery.
When a device is out of order due to your fault (its
fall, it is flooded with water, the power supply does not meet the specified
technical requirements, input signals exceed the norm, etc.) or there are
conspicuous marks of casing opening (broken warranty labels), it is considered
a non-warranty repair.
Within 1 year term we can advise you for free on the
device operation.
After-warranty service
After warranty termination I can arrange a paid repair
and technical maintenance of a device as well as I can sell you all necessary
spare parts for repair at minimum prices. I always have them in stock.
Packaging
Immediately after checking, the device will be wrapped
in several layers of strong air-bubble film and placed into a strong cardboard
box. Extra cardboard plates will be used for fixation.
If necessary, wooden box or pallet may be
used. For a more reliable fixation foam can be applied. The whole box will
be placed in a waterproof polyethylene bag which will be wound with several
layers of packing tape.
A special handle will be made for ease of
transportation.
Thus, I guarantee qualitative and conscientious
packing of the device that reduces to minimum the possibility of damage during
transportation.
Discount (from-10% to -90%)
I suggest you a device which is unique in its class
and price category with the following specifications: (accuracy, measurement
range, error, temperature operating conditions), endurance and durability
(military performance, aluminum, stainless steel, titanium or carbolite casing,
shock and vibration resistance, high maintainability and reliability), free
measuring kit (cables, adapters, load, fuses, etc.), 1year warranty.
Unused cheap
devices with the same specifications, accuracy and durability do not exist.
If you consider the price for this device unreasonably
high, and you know the similar equipment at a lower price, please, let me know.
I will help you to compare these two models. In case your
model (which is cheaper) is the same as the device I suggest or even it is
better, then
I guarantee to sell you a unit at that cheaper price with additional 10%
discount.
