Tensile testing machine precision affected by what way?1
Sensor depends completely determines the tensile testing machine precision and reliability of measuring forces, sales on the market at present stage some tensile testing machine use small force sensor value generally with S type sensor, full value generally with hub-and-spoke sensor, inside is full of resistance strain sensor chip, if resistance strain gauge accuracy is not too high or fixed resistance strain gauge with rubber aging resistance of the ability to work is not very good raw material is not very good or the sensor will be harm to the precision of the sensor and its lifetime directly. Tensile testing machine screw if there is space words make experimental data information in the future, will be directly should ring experiment of large deformation and break elongation. Sales on the market at present stage universal tensile testing machine screw is made of t-shaped general screw, then one is space relativity, the second is the friction force is relatively large, short life. Sales on the market at present stage some tension tester use reducer, some choose average skin produce transmission, these two transmission methods are the key disadvantages of: a must add grease, on time in front of the latter is to ensure that no transmission synchronization, can harm the experimental results. Tensile testing machine chooses currently on the market or general three-phase motor frequency conversion motor, this kind of motor selection pulse signal manipulation, manipulation of reflect slower, positioning is not accurate, general shifting narrow category has a high speed, no low gear or have a low gear, there is no high speed, and speed control is not accurate. Sales part of the tensile testing machine automatic control system on the market of choice is eight single-chip microcomputer control, sampling rate is low, and the anti-interference ability is bad, moreover is the AD converter if the ten digits of AD converter is the screen resolution is low, so accurate measurement is not allowed. Tensile testing machine drive is to adjust tester rate and maintain the core parts of the force value when heard all normal motor, and the device does not work, because the vast majority is drive set or route problem, must communicate with the manufacturers technical exchange and specific guidance, generally don't have to put the drive repair or conversion. Tensile testing machine is according to the working pressure of hydraulic oil to carry out the work, if the winter water temperature is too low, just start the heating must be more than ten minutes, or don't work in short time would happen. The interpretation of the above is the cause of the tensile testing machine precision, hope can help you, if you want to learn more about information of tensile testing machine, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!

The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
