U.S. SENSOR TEST REPORT
Thermistor Assembly Part Evaluation

(H7183 Style Pipe Temperature Sensor)

Part Number: H7183

Part Description: Pipe Temperature Sensor

Test Specification:

SPECIAL

Test Condition (s):

Parts were immersed in a 5% salt water solution, the solution temperature was cycled from ~+30°C to ~+80°C 14 cycles per day. During the duration of the test, 12 volts D.C. was applied continuously to each circuit consisting of a 20K Ohm resistor in series with each D.U.T.

Following the salt water immersion test above, the thermal shock test below was performed

Shock test (10 cycles 0°C salt water to +80°C salt water)

Test Start Date: 09/18/06
