Using high-temperature fluorine rubber seals, it can adapt to a wide temperature range.PBS-510 series thin film vacuum gauge (transmitter)outputSignal is commonly usedstandardModel, standard with0-5v/0--10V4-20mA/1-5；Can directly provide A/D data acquisition for PC and PLC, in order toWidely applicable for precise vacuum measurement and automation control of equipment in industries such as machinery, metallurgy, power, chemical, energy, environmental protection, food, light industry, etc.

The laboratory precision vacuum gauge of PBS-510 series thin film vacuum gauge can be used as a precision level 0.1 vacuum pressure measuring standard,Used for scientific research laboratories and metrology roomsThe measuring standard device. When used as a measuring standard, our company can assist in sending it for inspection and obtain approval from the Provincial Institute of Metrology TechnologyThe CNAS metrology calibration certificate shall be delivered together to achieve standardized metrological transmission (for vacuum sensors that are matched with precision measuring instruments in other professions, standardized transmission is also necessary for their data to have legal validity).

The capacitive thin film vacuum gauge is currently the best available for low vacuum measurement (00A vacuum instrument with a working pair standard of 01-100Pa, and the vacuum gauge we commonly use is often an indirect measurement vacuum gauge such as a resistance gauge, thermocouple gauge, etc. It is a heat conduction type vacuum measurement method. Due to inherent deficiencies in measurement principles, the measurement accuracy and stability of this type of vacuum gauge are not ideal. Its measurement error is generally 1-2 orders of magnitude larger than that of a thin film vacuum gauge. In addition, the use of resistance meters and thermocouple meters requires zero and full-scale calibration almost every time before measurement, which cannot guarantee the repeatability of measurement and cannot be applied to online measurement automation control. In addition, it is even more difficult to measure gases with extremely large and small molecular weightsIt is necessary to multiply different correction factors according to the different gases, and the value of the correction factor is often in the range of0.2～2.8↑）Scope，sometimesThe composition and proportion of gases are often dynamic,So it's harder to correct.There is also corrosion resistance. Thermocouples and resistors require direct contact with the measuring medium, and their corrosion resistance is even worse. Ordinary gauges are easily damaged.

The PBS-510 series vacuum degree transmitter, which adopts the measurement mechanism of capacitive thin film vacuum gauge, effectively solves this problemsomedifficultyCeramic thin film can sense small pressure changes in the medium on a flat surface, and when combined with corrosion-resistant materials, it can manufacture corrosion-resistant vacuum pressure sensors and transmitters with high sensitivity, high resolution, and high precision levels.

Besides,Output of thin film vacuum gauge transmitter0--5V/0-10V4-20ma\\1-5vwaitstandard signalThe linearity is very good，Whole process linearity<0.1%(This is also why secondary instruments can conveniently achieve effective digital vacuum degree display instead of the power index display of traditional vacuum gauges). Its full range resolution is above one ten thousandth. So, the ceramic thin film vacuum gauge transmitter isVacuum measurement and control system for modern industrial automationHigh precision instruments and equipmentIdeal high-precision sensor(Looking at imported high-precision instruments and equipment, every one uses a thin film vacuum gauge to measure vacuum degree.).
