    Snow Depth Sensor SHM 31 Generation of the measurement results Generation of the measurement results 4.1 Measurement values (cur, avg) Factory setting: The current measurement value is an average of the measurement values over 60s. The sensor performs a new measurement every 10 seconds, therefore the current value is an average of 6 measurements.

  • Page 16: Installation

    5.1 Installation instructions Please avoid starring into the laser beam of the SHM 31. Do not switch the SHM 31 on until the final assembly and alignment has been completed. 5.2 Assembly The snow depth sensor is mounted on a mast using the available mast clamps. The sensor is oriented towards the surface.
  • Page 17 Snow Depth Sensor SHM 31 Installation In the first installation step, the mast clamp itself should be fixed to the mast. After that the sensor can be mounted on the mast clamp using the 360° pattern disc and the tri star knob to position and adjust the sensor.
  • Page 18 Figure 15: Mounting direction and angle of the SHM 31 for best performance. In contrast to the SHM 30, the angle at the SHM 31 no longer has to be measured manually and communicated to the sensor. The SHM 31 has a built-in 3 axis acceleration sensor.

  • Page 19: Connections

    Snow Depth Sensor SHM 31 Connections Connections An 8-pin connector is located at the rear of the sensor's internal housing. This is used to connect the supply voltage and the data interface. A connection cable with a length of 15 m is offered separately.

  • Page 20: Supply Voltage

    Snow Depth Sensor SHM 31 6.3 Supply voltage The SHM 31 should be supplied with a DC voltage of either 12 or 24 VDC ± 10%. 6.4 Data interfaces The sensor has a half-duplex 2 wire RS485 interface for the configuration, data query and firmware update.

  • Page 21: Start-Up Procedure

    7.2 Switching the device on As soon as the SHM 31 is supplied with power, it starts with its internal measuring cycle and can be addressed via RS232 and via RS485 or SDI-12 connection depending on the selected setting.
