Guildline Industries 9330

Guildline series 9330 Standard Resistors contain hermetically sealed resistance elements. Its design is based on a thorough reappraisal of all earlier resistor designs, the aim of the program being the significant reduction of each “classical” source of error; temperature coefficients and variations therein; thermal as well as electrical time constants; thermal EMF’s; and voltage and power coefficients.

The resistance wire element is suspended in oil in a hermetically sealed case with a cover plate of low leakage acrylic. The connections to the resistance element are made in a four-terminal configuration, with the potential terminals mounted on the cover plate and the current terminals on the horns.

All terminals are solid thermal copper to reduce thermal EMF’s. Models 9330-10M & 100M have a cover plate made from Delrin acetyl thermoplastic and use a two-terminal configuration plus a ground terminal (no horns). Values below 10MΩ are designed to be immersed in temperature controlled oil or air baths.
