The laser components of the optical transceiver and the photoelectric conversion module are most resistant to the impact of the instantaneous pulse current, so it is not appropriate to switch the machine on and off frequently. The UPS power supply should be configured in the center front-end room of the optical transceiver and the 1550nm optical transmitter optical amplifier set-up point to protect the laser module and protect the photoelectric conversion module from the pulsed high current.
(2) Keep a ventilated, heat-dissipating, moisture-proof and clean work environment during use of the optical transceiver
The laser component of the optical transmitter is the heart of the device and requires high working conditions. In order to ensure the normal operation of the device, the manufacturer has installed a cooling and heat removal system inside the device. However, when the ambient temperature exceeds the allowable range, the device cannot Normal work, so in the hot season, when the central engine room has more heating equipment and poor ventilation and cooling conditions, it is best to install air-conditioning systems to ensure the normal operation of the optical transceiver.
The core diameter of the optical fiber core is in the micron range. Fine dust enters the pigtail active interface and blocks the propagation of the optical signal, causing a significant drop in optical power and a reduction in the signal to noise ratio of the system. This type of failure rate is approximately 50%. Cleanliness is also very important.
(3) Monitor and record operation during use of optical transceiver
Optical transmitters are equipped with microprocessors to monitor the various operating parameters of the system's internal operating status acquisition module, and are displayed visually through LED and VFD display systems. In order to promptly remind the check-in personnel, an audible and visual alarm system is installed in the optical transmitters. Maintenance personnel can ensure the normal operation of the system as long as the cause of the fault is determined based on the operating parameters and they are processed in a timely manner.
Position sensors are used in a wide range of automation and measurement applications. A key step in selecting a suitable position sensor is understanding the requirements of sensor size, resolution, repeatability, accuracy, mounting constraints and environmental ruggedness. This paper discusses the available position sensing technologies and concludes with a key feature comparison.
Linear position sensors measure the distance between an object and a point of reference, as well as changes in position. They do this by converting displacement into an electrical output. A wide variety of measurement principles can be used to let you make precise and reliable measurements for a broad range of applications. Linear position sensors and measurement systems are used in industrial applications as well as in scientific laboratories.
Within their specified measurement range, LVDT sensors provide excellent linearity. They are capable of detecting very small changes in position and have virtually unlimited resolution. As a result, LVDT sensors are also suitable for measuring high accelerations and high measurement cycles.
Linear inductive position sensors are durable, long-lived, and especially stable under temperature fluctuations. That means they are ideal for measuring linear travel in almost any industrial setting – especially with hydraulic or pneumatic applications.
