PRODUCT CODE: RBS/RBS


The temperature measurement industry has grown to expect only the highest quality products from PMC A Division of R-SCC.


PMC SURVEY WIRE is designed specifically to meet the demands inherent in the performance of an oven survey for load thermocouples as well as other heat treat application. This construction is designed to withstand continuous temperatures as high as1400°F (760°C) with excursions to 1600°F (872°C).

This FILAFLEX® insulated SURVEY WIRE design consists of single conductors insulated with high tensile strength, low alkali magnesia alumina silicate vitreous fiber braid. Once this material has been braided onto the wire it is impregnated with a proprietary binder to improve moisture and abrasion resistance as well as enhanced "pushed back" characteristics. The singles are then laid parallel and a braided jacket of the same high temperature fiber is applied. The jacket is then impregnated with a proprietary saturant to inhibit fraying.

This special construction allows ease of cutting, junctioning and other typical handling problems associated with soft thermocouple wire insulations.

You will find our qualified sales and engineering staff eager to assist in selecting a design to meet the requirements of your specific application.

Variations of this construction are available upon request including protective metal coverings for improved abrasion resistance.

NOTE: Percent limits apply directly to temperature in °C units, but for °F equivalents are applied to the numbers of °F above or below the ice point (+32°F).
(i.e. Limit (°F) = (Temp. °F-32°F) x Percentage)
Thermocouple wire cannot be expected to meet the limits of error at temperatures below the ice point unless specified at time of purchase.

Tolerances:

Due to allowances in manufacturing processes for wire, cable and similar products, PMC-A Division of R-SCC reserves the right to ship variation of ± 10% from the quantity of such goods ordered. Physical tolerances shown are nominal. Shipping weights are an average of all types of conductors and are listed for estimation only. These weights can vary substantially due to different types of spools, reels and/or conductors.

The material contained in the document is presented in good faith and believed to be reliable and accurate.
