Outdoor temperature probe LKM474
The LKM474 is an analog air temperature sensor with integrated measuring transducer. This converts the temperature-dependent resistance value of the sensor into a standard signal of 0...10V. It can be used to measure the temperature outdoors or in damp rooms. It is suitable for direct connection to an evaluation device for the PC or a PLC. The sensor is supplied fully calibrated. Minor corrections can be made on site using two controllers.
The components of the integrated measuring transducer are specially protected by dip coating.
The selection menu is available for standard configuration and can be used for typical settings.
These can be specified directly in the optional comment field below the selection menu.
Important Conditions: Please ensure that the measurement range falls within the specification limits of the respective sensor and has a minimum span of 20K. This guarantees that the desired range is technically feasible.
Our team will review your order for feasibility. If any issues arise, we will contact you to find a suitable solution.
Other configurations are also available on request:
Individual sensor tube lengths with Pt100 or Pt1000 in various accuracy classes,
Transmitters with measuring ranges that can be configured on site using DIP switches or a built-in head transmitter that is fully encapsulated in polyurethane (for use in particularly harsh environments).
