Ultraviolet Digital Probe Characteristics
1. The LS129 UV digital probe has a very small size, and the detector and controller adopt a split design, which is very convenient for installation where measurement is needed. It is also possible to combine the detector and controller with screws for measurement.
2. It adopts standard RS485 communication interface and MODBUS communication protocol. This UV intensity meter is equipped with high temperature wire capable of withstanding temperature of 200 ℃, which can realize online monitoring in real time for a long time.
3．The probe is powered by a 5-24V ultra-wide DC power supply range, which is very convenient for use in different industries on spot.
4. Free computer debugging software for communication protocol debugging.
Communication Parameters
1. Station No
The LS129 smart digital probe supports the standard MODBUS protocol. The default communication address is "1". You can modify the probe communication address through the "Human Machine Debugging Tool" or the communication protocol. The address setting range is 1-247.
2. Baud rate
The default baud rate of the UV digital probe is 9600bps. The baud rate can be modified through the "Human Machine Debugging Tool" or communication protocol.
3. Protocol
Supports the standard MODBUS protocol. You can read the probe measurement data and set the communication address and baud rate through the communication protocol. For detailed communication commands, please refer to "LS129 Digital Probe Communication Protocol".
