PyroMiniBus non-contact infrared sensors measure temperatures from -20°C to 1000°C and
provide an RS485 Modbus RTU interface.
The sensors are capable of being used in ambient temperatures up to 120°C without cooling
(XCF models: 70°C). They may be connected directly to third-party Modbus Masters, and they
are compatible with the optional PM180 6-channel touch screen interface, which provides
temperature display, data logging, alarms and analogue outputs.
A 6-channel junction box (model PMBHUB) is available to easily connect PyroMiniBus sensors
to the PM180 as a complete temperature measurement system.
