Transmitter LKM154B
Transmitter LKM154-B for Pt100/Pt1000 and thermocouples
The LKM154-B is a digital, programmable transmitter with an LCD display and is mounted in a special BUZH connection head. It can be set for various thermocouples according to DIN EN 60584 as well as for Pt100 and Pt1000 measuring resistors according to DIN EN 60751. It is battery operated and no standard signal output is available. Lead resistances are compensated by means of a four-wire circuit. A three- or two-wire circuit can also be implemented. Temperature compensation for thermocouples is done in the transmitter itself.The transmitter is supplied in a customer-specific configuration. A subsequent modification of the sensor can be done with our communication interface "LKM S1" with adapter A1 and a PC. The required program is available free of charge in the tab "Downloads". With this additionally the measuring data can be acquired and recorded.
For a small correction an offset can be set by software.
Delivery scope:
- LKM154-B
- CR123A battery
Via the connection thread M24x1.5 this transmitter can be completed with a temperature sensor to a complete measuring assembly. We would be pleased to provide you with an individual offer for a complete measuring assembly according to your specifications. You can request this with the button >>Ask about product<<.
