Oil-Well Temperature and Pressure Measurement System
The oil-well temperature/pressure system combines a dedicated fiber-Bragg-grating wavelength analyzer with FBG temperature/pressure sensing cable. The portable analyzer has a 7-inch color LCD touchscreen and a rechargeable battery for 10 hours of continuous operation. The cable structure addresses downhole installation and sensor survival. High-temperature and corrosion resistance, electromagnetic immunity, intrinsic safety, absolute measurement, compact size and multiplexing suit long-term, high-precision distributed casing-pressure and temperature measurements in oil/gas wells. The system has been used at Daqing Oilfield. FBG temperature/pressure sensors have a reliable structure suited to deployment. Monitoring can use a portable 16-channel wavelength analyzer with battery operation exceeding 10 hours. A steel-strip sensor design improves survival during and after deployment.

TY-HAST accelerated-life test chamber TY-HAST-40 Other Measurement Instruments Tianyiruihe
Test-chamber dimensions [φ*D]: 400 mm × 500 mm Outer-Carton Dimensions [W*H*D]: 709 mm × 950 mm × 1674 mm Temperature-control range: 100°C-135°C
The accelerated-life chamber is widely used for integrated circuits, microelectronics, ICs, and related fields. Increasing environmental stresses such as temperature and operating stresses such as applied voltage or load accelerates testing and shortens product or system lifetime tests. It investigates sample wear-out and service-life failures, the form of the failure-distribution function, and the causes of increasing failure rates.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
