FIGURE 11-2.  SDMS-30 Mounting Angles 

TABLE 11-1 SDMS-30 Mounting Procedure 

Step 

Procedure 

Attach the L shaped mount to the flat back mount using the common hole and crescent 
shaped screw holes. 

Using Figure 11-2, decide which angle your sensor is to be mounted at. 

Bolt the L shaped mounting piece to the underside of the sensor. The big middle circle should 
line up with the cable connector. 

Install sensor and mount 1 meter above maximum seasonal snow depth height. For mounting 
to poles, use thin hose clamps.  

Line up the connector end of the cable to the cable connector on the sensor. Lightly push the 
connector into place and screw the connector to secure.
