功能特性
• The high-precision quartz Bourdon …：The high-precision quartz Bourdon tube sensor 7250 high-speed digital pressure controller is Rosska's fifth-generation automatic pressure controller. It has unrivaled performance and a large-screen color Chinese interface display,and enhanced control stability,integrating precision,Stability,speed and versatility all rolled into one. The 7250xi,7250i and 7250 with a measuring range within 17.2MPa are equipped with Rosska's unique quartz sensors. The performance of each quartz sensor is rigorously tested by Rosskar pressure calibration equipment to ensure that high accuracy is provided to users. , high stability and high reliability products.
• Standard Accuracy For applications…：Standard Accuracy For applications that do not require the high-precision instrumentation of the 7250xi and 7250i, the 7250 provides cost-effective automated pressure testing and calibration. The pressure range is within 17.2MPa, and the accuracy is ±0.003% of the full scale. For the pressure range of 21MPa, the accuracy is ±0.01% of the full scale, and three range options are available: 7MPa, 14MPa and 21MPa, and the accuracy is ±0.01%FS of each range.
• Flexible and changeable control me…：Flexible and changeable control methods
• High-speed pressure control of all…：High-speed pressure control of all 7250 series instruments, within the range of 17.2MPa (7250 to 21MPa), for a load volume of 245cc, can stably output the set pressure value within 15 seconds or less, without overshoot pressure, can Perform high-speed stress testing and calibration.
• Dual control mode The 7250 series …：Dual control mode The 7250 series has two control modes: active mode and passive mode for users to choose. In active mode, the 7250 maintains set-point pressure and automatically compensates for pressure changes caused by temperature changes or pressure leaks. In passive mode, the user can define the control error bandwidth. Once the instrument output pressure is within the error bandwidth, the instrument stops controlling. In situations where there is no leakage and the temperature is stable, the passive mode can maximize the high-precision performance of the instrument and eliminate the interference of uncertain factors such as control fluctuations.
• Pressure automatic testing and cal…：Pressure automatic testing and calibration
• Automatic pressure test and calibr…：Automatic pressure test and calibration 7250xi, 7250i and 7250 are very convenient to use and can be automatically calibrated using a variety of methods.
• Up/down stepping is used for calib…：Up/down stepping is used for calibration with a fixed step size. Enter the user-defined step size. The 7250 series uses the Jog Dial (dial) method to automatically add or subtract the step size instead of a lengthy keyboard operation process.
