- Data Brochure

The tekmar Snow / Ice Sensor 090 / 094 and tekmar Sensor Socket 091 are used

with all tekmar snow / ice melt controls. The 090 has a 65’ (20 m) cable while the

094 has a 208’ (64 m) cable.

The Snow / Ice Sensor is designed to sit flush with the slab surface after being

mounted into the Sensor Socket. The socket is installed directly into the snow melt

slab halfway between the heating elements or pipes.

The sensor measures the slab temperature, sensor surface temperature and

sensor surface moisture level.

socket and conduit can be installed in order to provide a backup sensor location if the first location is not found to be ideal. • Vehicle tire and pedestrian traffic can track water and contaminants onto the snow melt area. If the snow / ice sensor is located in the traffic area, snow melting will be triggered by the passing traffic. This may be desirable in commercial areas where excessive traffic can cause the surface to become icy.

The mounting plate can be fastened to the ground by driving 1/2” (12.7 mm) rebar through the four holes located on each of the four corners and then tying the mounting plate to the rebar. 1) Cut four pieces of rebar at least 12” (300 mm) long. 2) Drive the rebar into the ground through each of the mounting plate rebar holes. Leave approximately 2” (50 mm) of rebar above the ground. 3 3 4 4 2 5 2 2. Socket screw holes 1 2 4 Mounting Plate 1. Drainage hole 3. Rebar holes 2 4.

Install the Sensor and Cable When the snow melt surface is finished, remove the plastic plug from the socket and fish the cable through the conduit until there is only 6 to 12” (150 to 300 mm) of cable between the sensor and conduit. Loop this remaining extra wire in a loose coil so as to not twist it, and place it, and the sensor into the socket. Secure the sensor to the socket with the four screws provided, making sure the “O” ring is in place and properly seated.

Testing and Troubleshooting TEST THE SENSOR When performing these tests: • The sensor head should be installed in the slab. • The five cable wires at the control should be disconnected (unplug terminal plug). • Use a good quality electrical testing meter with an ohm scale range of 0 to 2,000,000 Ohms. The sensor has two 10k Ohm thermistors. One reads slab surface temperature, and the other checks sensor heater temperature.
