Depending on the spray gun, a paint resistance of 0.04 to 1 megohm
usually is considered acceptable for good electrostatic spraying.
Kryoflex has an electrical resistivity of 1x1018 Ohms/cm and easily maintained resistance values exceeding 50,000 megohms
. Kryoflex seals allow the use of copper alloys so this connector has up to 70 times the current-carrying capacity of conventional products.
Insulation resistance is a minimum of 100,000 megohms
at 25[degrees]C and 10,000 megohms
200 V common-mode rejection, high input impedance (2 MegOhms
, typical) and factory pre-settable gain to accommodate low-level sensor inputs are also included.
As a general guideline, the feed water required for producing humidity within a chamber should have a specific resistance of 0.5 to 1 megohms
. Some environmental chamber manufacturers include disposable cartridges to purify water, while others require the customer to find a suitable water supply.
Our arium[R] ultraviolet water purification system produces ultrapure water with a resistivity up to 18.2 megohms
x cm with Total Organic Carbon (TOC) levels as low as <1 ppb.
Other electricals include initial contact resistance of 10 milliohms maximum, insulation resistance of 1,000 megohms
minimum, and dielectric strength of 3,000 V rms between terminals and frame.
The electrical measurement capabilities include five ac/dc voltage autoranges from 400 mV to 1000 V, two ac/dc current ranges from 400 mA to 4 A, and six resistance autoranges from 400 ohms to 40 Megohms
. The temperature measurement capabilities include 12 |degrees~ C/ |degrees~ F ranges from -200 |degrees~ C to +1372 |degrees~ C (-328 |degrees~ F to +2502 |degrees~ F) with 0.1 |degrees~ C resolution to +1000 |degrees~ C.
If winding leakage resistance drops to I megohm
or less, the pump is locked out and an alarm initiated.
