What is claimed is: 1. A sensor protecting device, comprising: a sensor housing having a first plurality of link ends extending in a first direction, the first plurality of link ends having a proximal portion, a distal portion, and a first transverse opening defined therein, the sensor housing having a second plurality of link ends extending in a second direction opposite the first direction, the second plurality of link ends having a proximal portion, a distal portion, and a second transverse opening defined therein; at least one first slot disposed at the proximal portion of the first plurality of link ends; at least one second slot disposed at the proximal portion of the second plurality of link ends; a sensor disposed in the sensor housing; and, a sensor cable disposed in the at least one first and second slots. 2. The sensor protecting device of claim 1, wherein the at least one first slot comprises a pair of first slots disposed on opposite sides of the first plurality of link ends. 3. The sensor protecting device of claim 1, wherein the at least one second slot comprises a pair of second slots disposed on opposite sides of the second plurality of link ends. 4. The sensor protecting device of claim 1, wherein the at least one first and second slots are disposed transverse to the first and second plurality of link ends. 5. The sensor protecting device of claim 1, wherein the first and second slots are arcuate. 6. The sensor protecting device of claim 1, wherein the first and second slots are integrally formed in the proximal portions of the first and second plurality of link ends. 7. The sensor protecting device of claim 1, wherein the sensor comprises a strain gauge. 8. The sensor protecting device of claim 1, wherein the sensor comprises a load cell. 9. A sensor protecting device for use in a lift truck having a chain mounted sensor attached to a carriage, the sensor protecting device, comprising: a sensor housing having a first plurality of link ends extending in a first direction and capable of intercalating with the chain on the lift truck, the sensor housing having a second plurality of link ends extending in a second direction opposite the first direction, the second plurality of link ends capable of being connected to the carriage, the sensor housing having a pair of first slots disposed on opposite sides of the first plurality of link ends, the sensor housing having a pair of second slots disposed on opposite sides of the second plurality of link ends; a sensor disposed in the sensor housing; and, a sensor cable extending from the sensor and disposed through the pairs of first and second slots such that tension on the sensor cable is prevented from damaging the sensor. 10. The sensor protecting device of claim 9, wherein the first plurality of link ends contain transverse slots for receiving a connecting pin. 11. The sensor protecting device of claim 9, wherein the second plurality of link ends contain transverse slots for receiving a connecting pin. 12. The sensor protecting device of claim 9, wherein the first and second slots are arcuate. 13. The sensor protecting device of claim 9, wherein the first and second slots are integrally formed in the first and second plurality of link ends. 14. The sensor protecting device of claim 9, wherein the first and second slots are disposed transverse to the first and second plurality of link ends. 15. The sensor protecting device of claim 9, wherein the sensor is a strain gauge. 16. The sensor protecting device of claim 9, wherein the sensor is a load cell. 17. A sensor protecting device, comprising: a sensor housing having a central portion containing a sensor, the central portion having a first plurality of link ends and a second plurality of link ends extending therefrom, the first and second plurality of link ends having transverse slots; a pair of first slots disposed perpendicular to the plurality of first link ends, the pair of first slots disposed on opposite sides of the plurality of first link ends, the first slots formed at a junction of the central portion and the plurality of first link ends; a pair of second slots disposed perpendicular to the plurality of first link ends, the pair of second slots disposed on opposite sides of the plurality of second link ends, the second slots formed at a junction of the central portion and the plurality of second link ends; and, a sensor cable extending from the sensor and disposed through the first and second slots such that tension on the sensor cable is prevented from damaging the sensor.
