Temperature string

 

The ADL-TMK ® temperature string is used to measure temperature in
multiple depths of soil or water. The temperature string is also
used in thermal systems as well as in the monitoring of mining and buildings.
The string can be manufactured very flexible in length from a few meters up to
several hundred meters. The segmentation of the sensor modules can be done on
customer request.Up to 1000 meters long. The string can remain permanently
in the environment to be measured. Connection via 2-wire RS485 bus with
open vendor-independent Modbus-RTU protocol.
Up to 253 ADL-TMK® modules on one bus.

 

Advantages and functions

  • Flexible string up to 1000 meters in length (other lengths on demand)
  • Segmentation of the sensor modules can be done on customer request
  • More cost-effective than fiber optic temperature measurement, because the string can remain permanently in the environment to be measured
  • Long cable lengths possible via 2-wire RS485 bus
  • open vendor-independent Modbus-RTU protocol
  • Up to 253 ADL-TMK® modules can be connected to each bus or string

Wiring

  • Highly flexible, durable and waterproof cable
  • 4x 0.5 - 4 x 1.5 mm2 depending on the application

Communication

  • 2-wire RS485 Bus
  • Up to 253 modules are addressable on one bus
  • Modbus-RTU protocol, 19200 baud, 8n1, addresses 1-253
  • Cable lengths up to 1000 meters possible
