The DP DME

Product catalog summary
Overview: The DP DME is an accessory for the Digitech Professional and DP II, utilizing ultrasound technology to measure distances in forestry applications. It is designed to determine if a tree is within the plot radius by measuring the distance from the tree center to a transponder placed at the plot center.
Specifications: The DP DME measures dimensions of 57x30x30mm and weighs 25g. It operates on a 3.3V external power supply with a consumption of 7mA. The ultrasonic frequency is 25kHz, and it measures distances in centimeters with an accuracy of 1% or better, up to 30 meters. The interface is RS232 with a protocol of NMEA.
Components: The system includes a T3 transponder, monopod plot staff, and adapter. The T3 transponder is water-resistant, uses one AA battery, and is compatible with other Haglöf instruments. The monopod is made of lightweight aluminum, and the adapter allows for 360° measurements.
Functionality: The DP DME works with Haglöf Sweden computer caliper software, which can be customized to exclude trees outside preset plot limits. The software calculates the distance from the tree center to the plot center automatically during circular sample plot inventory.
Usage Recommendations: Position the T3 transponder at the plot center on the monopod staff. Measure the tree diameter with the caliper and activate the DP DME to determine the distance. The software compensates for the center of the measured tree for improved accuracy.
Environmental Considerations: The ultrasonic signals can travel around obstacles and are affected by air humidity and temperature. The instruments should stabilize at ambient temperature before use. External noise sources like waterfalls or traffic may impact measurements.
Package Options: The complete package includes the DP DME instrument, transponder T3, plot center staff, and adapter. A measuring unit only option is also available. Software upgrades are possible for licensed Haglöf Sweden software users.

The DP DME-1

The DP DME The DP DME offers possibilities to have a distance connected with each individual tree. When performing circular sample plot inventory, the distance to the plot centre from the centre of the tree is automatically calculated by the caliper software. The software can be programmed with functions to warn or refrain from registering trees beyond the preset plot border. The DP DME distance measurer is an instrument accessory for the Digitech Professional and the DP II. With the DP DME, measurements to determine if a tree is within the plot radius are performed with the help of ultrasound technique. The DP DME uses ultrasound to measure distances. The ultrasonic method is well proven and used in instruments such as the Vertex IV, the Vertex Laser and the DME. To measure with the DP DME, the T3 transponder is placed in the plot centre on a monopod staff. The DP DME is installed on the caliper comport and works with the host computer caliper and corresponding software. When measuring the tree diameter with the caliper, the DP DME can be activated to measure the distance from the tree centre to the transponder, placed on the monopod staff in the plot centre. The DP DME accessory will work with most Haglof Sweden computer caliper software applications after upgrading. The software can be customized to, for example, refrain from registering trees outside pre-set plot limits. The host computer supplies battery and display for the DP DME, and all instrument functions are software run. TECHNICAL SPECIFICATION DP DME Dimensions: 57x30x30mm, 2.28"x1.2"x1.2',. Accessories: Transponder T3, monopod plot staff, adapter. Position the T3 transponder in the plot centre on the monopod staff. The monopod, used for the DP DME, the Vertex IV, the Vertex Laser and the DME, is customized for use in tough field conditions. Measure the tree diameter with the caliper and activate the DP DME in your computer terminal. The software will determine the distance from the tree centre to the plot centre. Recommended software for the DP II with DP DME accessory: TIMS for standing trees art. no. 14-104-1052 Haglof SWEDEN
