Handheld

Overview The handheld roll gap checker is specially used to measure the length between spherical surface, arc surface and plane (or spherical surface). It is specially suitable for the opening adjustment of the roll gap of the metallurgical continuous casters in various specifications, because the roll gap checker has the advantages of high resolution, accurate measurement, stable data and easy to use. Because the opening accuracy of the roll gap checker will directly affect the quality of the casting block, this roll gap checker is an indispensable testing equipment in the continuous casting equipment, which can fully meet the needs of on-site installation testing and use process verification. When the hand-held roll gap meter smoothly passes through the gap between the guide rolls of the continuous casting machine, the upper measuring contact of the hand-held roll gap checker contacts the inner arc roll and the lower measuring contact touches the outer arc roll. The handheld roll gap checker is used in perpendicular to the roll diameter direction, during the pushing process, when the hand-held roll gap meter is in the tangent plane of the upper and lower rolls, the measured value is the smallest at this time, and this value is the roll gap measurement value. The design of the hand-held roll gap gauge ensures that the upper and lower contacts of the roll gap checker can smoothly pass the measured roll along a straight line during measurement. During the measurement process, the roll gap measuring instrument automatically compares the measured values, and displays the minimum measured value on the instrument display interface, which is the current measured roll gap value. The introduction of different types The measuring range of the split hand-held roll gap checker is 180mm - 400mm This hand-held roll gap checker adopts the design that the measuring body and the display instrument are separated. The measuring body can be clamped by an extension rod, which is suitable for online maintenance and measurement of wider slabs, and it is convenient to use the extension rod to send the measuring body into the continuous casting section to measure inside and we can see measurement data on the checker outside. The measuring range of instrument type handheld roll gap checker is 120mm - 400mm This hand-held roll gap meter is light and compact, and it is convenient to carry during maintenance. The measurement value can be seen immediately after measurement, easy to use, and can be equipped with a short measuring rod. It is suitable for the maintenance and measurement of slab online and offline continuous casting sections. It has data printing function, the measurement results can be printed in real time. The measuring range of thin slab hand-held roll gap checker is 60mm - 150mm This handheld roll gap meter is suitable for measuring the roll gap of CSP continuous casting machine and ultra-thin slab continuous casting machine. It is accurate and easy to use. The technical parameters 1. Measuring range of instrument type handheld roll gap checker: 180mm - 400mm (the range can be customized) 2. Measuring range of digital hand-held roll gap checker: 120mm - 400mm (the range can be customized) 3. Measuring range of hand-held thin slab roll checker : 60mm - 150mm (the range can be customized) 4. Measurement accuracy: 0.01mm 5. Working temperature: -25℃~+85℃ 6. Battery capacity: 5000mAh 7. Charger specification: 12V

Overview LGK-JS02-064 handheld thermocouple calibrator (referred to as thermocouple calibrator). The calibrator is specially used for thermocouple temperature measurement. It has built-in 2 high-precision and high-stability thermocouple temperature conversion chips, which can measure the temperature data of two-way thermocouples at the same time. It is mainly used to detect whether the function of the thermocouple is normal before and after use. The product design takes into account its application in industrial field, and the calibrator has been optimized in terms of stability, reliability and anti-interference, and can be applied to various complex working conditions. The appearance design of the calibrator strengthens the design of resistance to falling and oil stains. The overall calibrator is easy to use, intuitive to display, small and portable, stable and durable, and easy to operate. Working principle The LGK-JS02-064 handheld thermocouple calibrator adopts a special industrial chip for thermocouple temperature acquisition, reads the temperature data of the thermocouple sensor at a single point, and then processes the data through an industrial-grade low-power single-chip microcomputer, and then passes the digital tube displayed on the screen. Composition As shown in the figure, the device uses a self-locking metal button switch for switching on and off. The calibrator comes with a lighting design, which is mainly used for thermocouple maintenance with the poor light in the operating environment. The design fully considers the actual needs of field applications, and the design is very humanized and rational. The temperature data is displayed through a bright red digital tube, which is intuitive and convenient to check. When using the thermocouple calibrator, we need to connect the thermocouples in the unpowered state. The T1 interface is a group, and the T2 interface is a group. Make sure the connection is good. Press the switch, and the thermocouple calibrator will directly display the temperature of the thermocouple in real time. Parameters Acceptable test temperature range: 0-1000°C Sensitivity: 0.25°C Operating temperature: 0°C-50°C Temperature refresh rate: 0.5 s/time Common working section: 25°C-800°C Power supply: 2 AA dry batteries
