Transmitter LKM406 for Pt100/Pt1000
The LKM406 is an analog transmitter and can be designed for the Pt100 or Pt1000 measuring resistor according to DIN EN 60751. Its design is ideally suited for mounting in tubular housings. It converts the temperature-dependent resistance value of the sensor into a standard signal of 4...20mA. Lead resistances are largely compensated by means of a three-wire circuit.
The transmitter is supplied calibrated to customer specifications. By means of span and zero controllers, a subsequent fine adjustment can be carried out on site, if not encapsulated.
There are three variants available:
- without casting compound and with Hirschmann plug type GSP
- with casting compound and with Hirschmann plug type GSP
- without casting compound and without plug
With this arrangement, customer-specific probes with integrated transducer, such as our Type406 or Type409, can be realized.
The selection menu is available for configuration.
Please request individual measuring ranges beforehand using the >>Ask about product<< button.
In the case of analog transmitters, it may occasionally be the case that the desired measuring range cannot be realized. If the individual measuring range is confirmed by us, it can be entered in the >>YOUR COMMENTS<< field at the end of the ordering process.
