Product Details

The ED&D Hot Winding Resistance Measurement System is the industry-standard device that automates and simplifies the task of measuring the operating temperatures of transformer windings. The "rise of resistance" measurement is specified by UL, CSA, EN, IEC and other safety standards as the preferred method for establishing winding temperatures, since the result is an average temperature over the entire winding instead of a spot temperature as provided by a thermocouple.

The ED&D Hot Winding Resistance Tester takes out all of the tedious manual readings and calculations previously needed to perform this method of temperature measurement. It also has 8 channels and can be connected to a second unit for a 16-channel test capability! This feature packed device pays for itself in time savings alone. Competitive units are single channel only, and require purchase of numerous "optional" devices to even come close to our solution! This unit is being used by NRTL's such as UL, CSA, TUV, ETL and MET Laboratories. It's the only such device that is UL validated.

The Microsoft Windows based software guides the operator through each stage of the measurement process, while collecting and analyzing all the relevant data. At the end of the test, the program can create a report suitable for submission, and/or generate a spreadsheet file containing all the raw data for more detailed engineering analyses.

Product Details

This product measures the temperature in supporting surface and in the fixing surfaces for appliance and luminaries in operatiion-as required by many IEC/EN standards including IEC60335-1, IEC61010-1 and IEC60601-1. The harmonized EN, UL & CSA versions of these same standards also apply.

Product Details

This product is built in exact accordance with various IEC, EN, ANSI, CE, VDE, UL (such as UL 858) & CSA requirements. This device is used to verify safe surface temperatures of household appliances that can be fully contacted with probe tip.

Product Details
This product is for measuring surface temperatures: 10-32 tapped handle for attachment to ED&D Force Gauges. Built according to IEC 60335-2-6/FDIS: 2002.

Product Details

The tape is generally not considered a substitute for the paste. The tape is for: holding thermocouple in place so it can be reliably pasted at its bead, holding thermocouple during routing and to provide strain relief during test (may need high temperature tape) and to provide additional insulation for dielectric breakdown protection (thermocouple passes by high voltage parts).

Product Details

Available models include TCP-01 (125 g) and TCP-02 (250 g). Thermally bonds thermocouple bead to part being measured. A MUST for reliable temperature test results. This is what most testing agencies are using. Provided in an air-tight container. Choose between two amounts, depending on intended usage (a little lasts a long time).
