Abstract:
Accurate device-condition information of and relating to a number of devices to be managed are collected in an efficient manner. The number of devices to be managed are divided between a direct collection group comprised of some managed devices whose device-condition information are collected by detecting operation by a portable (mobile) unit for device condition detection on each one of these managed devices and an indirect collection group comprised of the other managed devices whose device-condition information are collected by communication between each one of these managed devices and a stationary unit disposed to be capable of detecting the device-condition information of the device.
Abstract:
A steam trap operation detector provided with a vibration detecting section and a arithmetric section. The detecting section includes a probe, a diaphragm for generating ultrasonic vibration in response to mechanical vibrations sensed by the probe and a vibration sensor for converting the ultrasonic vibration into an electrical signal. The detector also includes an arthimetric section for receiving an amplified signal from the vibration sensor and processing the same into information indicative of the operation of the steam trap.
Abstract:
Construction of a valve-member monitoring system using wireless communication is facilitated. The valve-member monitoring system is structured with operating-condition sensors each attached to each of multiple steam traps installed on a manifold. The manifold serves as a discharged condensate collecting pipe in which condensate is discharged through the multiple steam traps. The valve-member monitoring system further includes a sensor controlling terminal device that is attached to the manifold or in the vicinity of the manifold and exchanges information by radio with a central control apparatus. In the valve-member monitoring system, the terminal device is connected to the operating-condition sensors each attached to each of the steam traps installed on the manifold with lead lines. This reduces time and effort required to determine which operating-condition sensors are to be connected to the terminal device, and therefore facilitates the construction of the valve-member monitoring system, which are excellent results.

Abstract:
An apparatus including a slider part and a base assembly slidingly movable in relation to each other with the aid of a first guide rail and a second guide rail in the base assembly. The distance between the first guide rail and the second guide rail is adjustable while the apparatus is being assembled. A method is also disclosed.
Abstract:
A monitoring system with a power supply built therein, which is capable of setting installation expenses at low cost and obtaining a stable result of monitoring for a predetermined period. The monitoring system comprises a sensor unit having sensors and a power supply incorporated therein, and a portable data logger having a communication module and a power supply built therein. Physical quantities such as vibrations, temperatures, and pressure, of an object to be monitored are detected by the sensors, followed by transmission to the portable data logger, whereby the state of operation of the object is displayed.
