A monitoring device monitors a forming machine (target device). The forming machine includes a housing, a bearing attached to the housing, and a shaft placed radially inside the bearing. The monitoring device includes a plurality of heat flux sensors and a detector. The heat flux sensors are provided on the radially outer side of the bearing and spaced from each other in the circumferential direction of the bearing. The heat flux sensors output a signal corresponding to heat fluxes through faces thereof on the bearing side and faces thereof on the other side. The detector detects a load applied radially to the shaft or bearing, based on the output from the heat flux sensors.

The duplex calorimeter, connected between a first and a second demand sides to measure a caloric heat energy between the demand sides, includes a first pipe connected to the first demand side, a second pipe connected to the second demand side, first and second branch pipes, branched into two directions between the first pipe and the second pipe, a first flow rate measuring part measuring a flow rate of the heat energy in the first branch pipe, a second flow rate measuring part measuring a flow rate of the heat energy in the second branch pipe, a temperature measuring part measuring a temperature of the heat energy in either branch pipe, and a calculating part calculating the caloric value based on the flow rate measured by the first flow rate measuring part or the second flow rate measuring part and the temperature measured by the temperature measuring part.

A heat flux measurement system includes a first wire, a first heat flux sensor singly provided in the middle of the first wire, a second wire including a first end connected to the first wire at a position closer to a first end of the first wire than the first heat flux sensor in which the second wire is formed of the same material as that of the first wire, a second heat flux sensor singly provided in the middle of the second wire, a first detection unit detecting a voltage between opposite ends of the first wire, and a second detection unit detecting a voltage between the first end of the first wire and a second end of the second wire.

A sensor assembly includes: a base with an installation space; an electrical connection member disposed on the base; a sensing unit including at least two physical sensors and one integrated circuit board; and a contact member disposed at one end of the base. The sensor assembly is a combination of the temperature sensor and the vibration sensor, the main physical parameters (including back clearance, collision, thermal displacement and lubrication) regarding the operation of the linear motion transmission device can be calculated based on the temperature signal and vibration signals, without requiring the installation of separate different sensors. Therefore, installation space is reduced. The sensor assembly is directly abutted against the linear motion transmission device to detect the change of various physical values in a most direct manner.

Apparatus and methods are provided for providing flexible and repairable testing capabilities for systems that generate or absorb heat such as energy storage systems. One embodiment can include a temperature bath structure adapted to contain and maintain a fluid bath at a predetermined temperature, an outer containment structure adapted to insert into the temperature bath structure, heat sinks, thermal sensor assemblies, and an internal containment structure where the thermal sensor assemblies and heat sinks removeably attach to different sections of the inner containment structure so as to measure heat flow into or out of the inner containment structure's different sections. Embodiments of the invention enable rapid insertion/removal of samples as well as replacement of sections of the system including embodiments or parts of thermal sensor assemblies as well as enabling separate thermal measurements associated with different sections of a sample under test within the inner containment structure.
