Description
The TA284 humidity indicator plug provides a visible indication of moisture inside a sealed enclosure and is designed for internal pressures up to 500 psi. Its glass window is fused to a steel body with an electroless nickel finish.
The 3/4-14 tapered pipe thread fits a threaded boss and is installed with a 1-1/8 inch socket. The threaded connection does not require an O-ring or gasket; lock nuts and gaskets are not supplied. A porous filter and polyethylene spacer protect the indicator card, with a retaining ring holding the components in place.
Two standard configurations are available: TA284-40RWP with a 40% spot indicator, and TA284-6789P with a pie indicator at 60%, 70%, 80% and 90% relative humidity. Other discs may be available on special request.
The plug is suitable for NEMA 1, 2, 3, 3R, 3S, 4, 5, 6, 12, 12K and 13, and IP66/IP67 enclosures. Suitability for other enclosure ratings depends on the application.
