XYZIL Transmission Speed Sensor 258-4521 Compatible with Caterpillar CAT Off-Highway Truck 769D 771D 773D 773E 775E 777D 784B 784C 785B 785C 785D 789B 789C 793B 793C 651E 1440178 3E6955 7T6337 9X7000
XYZIL Part number: 258-4521 1440178 3E6955 7T6337 9X7000 || Compatible with Off-Highway Truck: 769D 771D 773D 773E 775E 777D 784B 784C 785B 785C 785D 789B 789C 793B 793C || Compatible with Wheel Tractor-Scraper: 651E || Hall effect sensors have Hall elements. Active Hall effect sensors require an external electrical power supply. Waveform is function of the target gear square wave output. Frequency is proportional to surface speed of the target gear as it passes the sensor, but the voltage level is not (unlike passive speed sensors). Hall effect sensors can detect down to zero speed (unlike passive speed sensors).

Information:
In many applications, the accuracy of the temperature contactor used in an alarm or shutoff system is very important. To accurately check the actuation temperature of a contactor, do not use a static water bath. Actuation temperature will be 10°C (18°F) or above the actual actuation point when the contactor is installed in an engine. Even using an agitated glycol bath can produce a 3 to 5°C (5 to 9°F) error.
In order to provide a rate of coolant flow high enough to insure accuracy, contactors should be checked in a running engine in a location with good coolant flow. Refer to the test procedure described in the reference.
