PyroMiniBus – Miniature Pyrometer with RS-485 Modbus for Multi-Channel Systems

PyroMiniBus – Miniature Pyrometer with RS-485 Modbus for Multi-Channel Systems


– Measure surface temperature from -20 to 1000°C on a variety of target materials, including painted surfaces, paper, plastics, asphalt, food, organic materials, rubber and many more.

– Touch screen terminal for configuration, display, alarms and data logging

– The PyroMiniBus is ideal as a low-cost, standalone 6-channel system, or it can be connected to a larger system using the PM180’s separate Modbus Master and Slave interfaces.

– Connect the PM180 touch screen terminal to another network as a slave device, using its secondary Modbus interface

– Analogue and alarm relay outputs via optional modules

– Conforms to industrial EMC standards

– Robust miniature sensors withstand 120°C ambient temperature without cooling

– Junction box for easy wiring (optional)

Field of View Diagrams

Please note: The given measured spot size contains 90% of the energy detected by the sensor. We normally recommend the target is at least twice as large as the given measured spot for maximum accuracy. Sensors may be used at longer distances than the above diagrams show. There is no maximum measurement distance in clean air; this is because the PyroMiniBus detects only the wavelengths of infrared radiation that are not absorbed by the atmosphere.
