Thermocouples

PLEASE SPECIFY THE OVERALL LENGTH OF THERMOCOUPLES DESIRED OR GIVE THE CAN DIAMETER IF THE THERMOCOUPLE IS TO BE INSERTED THROUGH THE SIDE OF THE CAN!

Ecklund Thermocouples are specially designed for conducting heat penetration tests of foods in cans, jars and plastic packages. Using the heat-districution thermocouples, the same heat penetration cable may conveniently be used for checking retort heat distribution. The non-projecteing connector type thermocouples combine convenience and accuracy. Also, they permit test containers to be filled and closed in the same manner as the commercial pack.

Ecklund-Harrison Technologies, Inc. manufactures all the equipment necessary for heat penetration tests except for the indication or recording instrument. The user may select instrumentation from the simplest single point indicator to the most elaborate computer system. It is necessary only that the instrumentation be of suitable temperature range calibrated for TYPE T (copper-constantan) thermocouples.

Correction factors have been published (FOOD TECHNOLOGY, 1956, Vol X No.1, Pages 43-44) to correct for errors resultin from heat conducted into heating fod products by the thermocouples and fittings. (We will send a reprint of this article upon request) No correction is normally needed for convection heating products or for thermocouples two (2) inches long or longer for any product. The four styles of thermocouples we manufacture are described on this page. Though they are quite different in appearance, they should provide virtually identical results.

EQUIPMENT FOR THERMAL DEATH TIME STUDIES Available for both thermal death time cans and thermal death time tubes. Write or call for details.

C-1 MOLDED PLASTIC THERMOCOUPLE
The "molded plastic" thermocouples are approximately on-quarter inch (6.4 MM) in diameter and are available only in standard can sizes (202, 211, 300-303, 307, 401-404, 603).

C-2 and C-3 TUBE AND ROD THERMOCOUPLES
Tube and Rod (plastic) thermocouples are available in any size from 3/4" (19 MM) to 14" (356 MM). They are approximately 1/4" (6.4 MM) in diameter.

C-4 FLEXIBLE THERMOCOUPLE
The C-4 flexible thermocouple is a 4" (102 MM) long insulated (24 gauge) wire thermocouple attached to a 7/16" (11 MM) long molded thermocouple body. Longer wires will be supplied on request. The C-4 style flexible thermocouple is useful in checking heat penetration in chunks of meat, corn on the cob, etc., or as an adjustable length thermocouple.

CNS and CNL NEEDLE THERMOCOUPLES
Needle type thermocouples are available in any specified length from 3/4" (19 MM) to 14" (356 MM). They feature a 1/16" (1.6 MM) diameter tubular stainless steel body. The small diameter probe has obvious advantages in measuring temperatures inside discrete particles such as chunks of meat.
