The OS-MINIHUB Infra red temperature sensors have RS-485/Modbus communications, which allows them to be used on their own or as part of a multi-point infrared temperature monitoring system, with optional touch-screen displays, relays and analog output modules.
OS-MINIHUB sensors are designed to measure the surface temperature of non-reflective materials in industrial applications, from -20 to 1000°C (-4 to 1832°F). They are sealed to NEMA 4 (IP65), built from 316 stainless steel, and fully tested to industrial EMC standards.
They can measure food, paper, thick plastics, asphalt, paint, bulk materials and organic materials, as well as most dirty, rusty or oily surfaces.
OS-MINIHUB sensors have an operating temperature rating of up to 120°C (248°F) with no need for cooling.
The sensors measure just 45 mm (1.7") long (plus cable gland), so they can fit into the smallest of spaces.
Up to 6 sensors can be connected to the optional TSD600 interface module, which provides temperature display, configuration, and high-capacity data logging to a MicroSD Card. Analog and relay outputs are available via separate DIN rail mounted modules.
With up to 6 sensors connected to one TSD600, the OS-MINIHUB is an ideal low-cost non-contact temperature measurement system.
To measure more than 6 locations, OS-MINIHUB sensors and TSD600 sub-networks may be connected to an RS485 Modbus SCADA system or PLC. It is possible to measure the temperature of hundreds or thousands of locations on the same network.
The OS-MINIHUB may be installed as a new temperature monitoring system, or integrated into an existing Modbus network. With two Modbus interfaces, the TSD600 makes an ideal local display for a group of sensors as part of a larger system. The OS-MINIHUB-JB6 junction box makes it easy to connect the system together. Never miss a critical temperature event. In condition monitoring applications, the OS-MiniHUB system is an always-on solution that can replace manual checks with a hand-held thermometer or expensive thermal imaging.
Fiberglass impregnated with epoxy is cured in an oven to increase strength. OS-MiniHUB sensors are placed inside the oven at up to 120°C (248°F), to build-up a temperature profile at many points on the entire surface of the workpiece, and to communicate the measured temperature to the heating system that controls the hot air blowers in the oven. Industries include boat building and aerospace as well as many others.
Check the temperature profile of bakery products at multiple points along a conveyor oven.
Corrugated Board Manufacturing
Monitor the web temperature along an entire corrugator, with local displays for each section of the production line, and centralized monitoring in the control room. Sensors withstand 120°C (248°F), and can be used in high temperature areas such as single facers without cooling.
Monitor the temperature of busbar joints in switchgear cabinets. Hundreds or even thousands of points can be monitored on the same network using the OS-MiniHUB system.
A large system of OS-MiniHUB sensors can monitor the paint curing process at several points. Monitor temperatures around the entire vehicle in environmental test chambers.
A network of OS-MiniHUB sensors can monitor all the bearing temperatures on a machine, a run-out table, or the whole factory. The OS-MiniHUB is ideal for measuring the temperature of all painted metal surfaces.
Arrays of sensors fitted on a rig of infrared curing lamps ensure an even temperature profile along the part being cured. Surface coatings, paint and epoxy are ideal target materials, among many others.
