The sensing portion of the sending unit must project at least
The resistance value of the sender unit is shown in table 1. The applied voltage and series resistance are specified in the table. Apply power to the sender unit for at least seven minutes before inspection.
Test the sending unit in a continuous flow bath.
- Medium for the oil bath ... UCON oil spec 50-HB-280X
- Flow rate of the oil bath ... 228.6 mm (9 inch) to 254 mm (10 inch) per second
