The foundation of software-defined access

Zero-Portable-V1 is a fiber optic thermometer developed for harsh measurement environments, especially where the ambient temperature is high and the dust and smoke are large. The temperature probe is made of stainless steel, has very strong mechanical strength, and is in a passive working state. Without any protection measures, it can work normally in an environment of 220 °C. The probe comes with an air blower. If necessary, the purified air can be directly connected to the air blower, which not only ensures that the optical lens is free from dust and oil pollution, but also reduces the temperature of the probe, thereby extending the temperature of the thermometer probe. service life. At the same time, signal attenuation caused by unclean transmission medium is avoided, thereby improving measurement accuracy. The standard FC connector is used to connect the probe and the conductive fiber, which solves the system discreteness caused by the assembly process and ensures multiple insertion and removal without precision loss. The circuit processing unit has the function of real-time display of the measured temperature, and user parameters can be set through the display window and buttons.

Zero-Portable-V1 combines visual sighting and optical fiber sensing. The visual sighting system is convenient for intuitively grasping the current working conditions of the measured target, and it can also be equipped with online video monitoring through the eyepiece system. The optical fiber sensing isolates the circuit processing unit to a relatively good working environment through the transmission optical fiber, which greatly improves the anti-electromagnetic interference ability of the instrument. At the same time, the circuit processing part is placed in a suitable working environment, which prolongs the overall service life of the instrument. The fiber length can be up to 100m.

Zero-Portable-V1 can usually be used for temperature measurement in hot blast stoves, kilns, coking furnaces, etc. A network can be formed in the temperature measurement system of the observation fire hole on the top of the coking furnace, and the temperature can be continuously measured online. It can dynamically control the coking time and the gas volume to achieve the purpose of high efficiency and energy saving.

In terms of hardware configuration and system design, abundant on-site parameters are reserved for users to adjust. User parameters include: emissivity, filter coefficient, measurement mode, communication parameters, etc., which can meet the temperature measurement needs of different customers, different environments, and different processes.
