Application of silicone oil in the field of instrumentation

Silicone oil is used as the liquid filled with silicone oil flash point instrument, with high(high temperature and evaporation, oxidation), the freezing point is low (low, not frozen),temperature and viscosity coefficient is small, and no corrosion resistance and other advantages, in almost all areas of instrumentation using silicone oil as the filled oildiaphragm type pressure, differential pressure transmitter capillary or measuring chamber, and a diaphragm pressure gauge is filled liquid.

Silicone oil is used as the measuring instrument isolation liquid and liquid, using silicone oil characteristics, in the isolation tank relative density greater than the measured medium high temperature resistant silicone oil, silicone oil into the instrument, economicand effective temperature measurement. The use of silicone oil with low freezing point,freezing temperature characteristics, in the cold north, with anti freeze liquid silicone oil as the isolation to prevent the instrument pressure pipe freezing and equipment. Inmeasuring the working fluid, using two isolation tank positive pressure isolating with fixed on the holder of the lower part of the upper cover, silicone tube with the gas holder height variation can be moved, negative pressure isolation tank and side pressure guiding pipe are fixed height piping installation, and in two in the isolation tank filling tolerance to low temperature and freezing oil as working fluid differential pressure transmitter, with thegas pressure changes caused by the change of the height and the height of the gas holder corresponding, can measure the gas holder level, both reliable and economical.

Silicone oil is used as the electronic instrumentation of damping and seismic fluidenvironment, in order to overcome the strong vibration or medium to strong pulsationpressure gauges bring damage, in the case of pressure meter in measure dampingsilicone oil filling and supporting buffer device made of general vibration proof pressure gauge, so it has a good seismic performance. It is easy to read the measured value, andensure the measurement accuracy.

Silicone oil is used as the instrument calibration using oil bath, heat resistance andthermal conductivity, high temperature oxidation resistance of silicone oil is good, usemodified silicone oil as heat carrier oil bath, than the traditional oil bath has the advantages of fast heating / cooling, smooth control, temperature stability and good constant temperature effect, extend the oil change period and a series of advantages, is the ideal the temperature of the oil bath heating thermostat and instrument calibration.

Silicone oil used in precision pressure gauge calibration, the precision instrumentcalibration pressure gauge calibrator of silicone oil, the use of bag storage device can discharge characteristics of energy storage, the pressure is stable, reduce the impactand return difference, can precisely adjust the hydraulic system, allowing the system to meet the requirements of precision pressure gauge calibration.

Silicone oil used for fixation and encapsulation of electronic components, the use ofmodified silicone hydrophobic solid silicon sealant, sealing and electric insulation, used for a variety of electronic components / modules of packing or packaging. For example,the insulation package packing, electronic components and devices of the capacitor(such as filling and sealing type flameproof measurement / package and integral temperature transmitter of the solenoid valve coil is installed for module encapsulationetc.).

Silicone oil is used as the thermal grease, electronic appliances and CPU, this kind of equipment or electronic devices to generate heat in the operation period. If the heat is not good, will make the device operating temperature, welding solder melting point.When serious cause electrical breakdown or stop working. For example, all electronic devices CPU and installed on a computer mainboard in the heat, in the summer, even though the fan speed to reach 2500 - 3000 r/min operation, the temperature inside the case is likely to reach more than 75 DEG C; sometimes reach more than 90 DEG C, thecomputer screen. According to the information, the use of a special instrument, the special properties of organic modified silicone oil cooling ointment on the CPU and heat sink of interstitials or high-power controlled silicon surface heat, obtain good cooling effect.

Silicone oil is used as the hydraulic oil pressure switch, with 201 - 100 - two methyl silicone oil (hydraulic oil viscosity is less than or equal to 100mm2/s) as large diameterhydraulic valve, because of its high viscosity, resistance, wear resistance, corrosion resistance and high temperature oxidation of proper lubrication, the oil pressure switch valve with the same caliber pneumatic on-off valve compared to not only small volume and light weight, but also has better hydraulic energy, work flow and good sealing,prevent leakage and long service life, safety and a series of advantages.

Silicone oil used in high vacuum equipment, excellent oxidation resistance of the siliconeoil diffusion pump and has anti radiation performance and low pressure saturated steam,widely used in atomic energy accelerator, electron microscope and high vacuum system and a television picture tube, power tube, microwave electron tubes and other electronic tube cathode production.
