Rainbow Run precision instrument, roundness, cylindrical instrument, profiler

Using the subject liquid, gas, vapor pressure measurement, the liquid level measurement. Features ● High accuracy, good stability. ● wire operation, 4 ~ 20mA signal output. ● sensitive components and circuit boards are all-solid structure, strong vibration. ● anti-interference ability, good temperature stability. ● Explosion-proof housing structure, all-weather use. ● has the best corrosion resistance, to ensure the best cost-effective antiseptic. ● compact structure, simple and reasonable, no support, no horizontal installation can be directly installed in the pipeline at any position. K1 type K2 type works medium pressure directly on the ceramic sheet, the measurement diaphragm shifted. Normal pressure diaphragm offset 0.025mm, overpressure diaphragm offset only 0.1mm. In this case, the measuring diaphragm attached to the ceramic brackets, to avoid damage. Capacitance diaphragm displacement produced by the electronic components directly connected to detection, amplification and conversion to standard signal output. Measuring system wiring diagram in the system circuit must be shielded signal cable, and grounded. Measurement system diagram (4 ~ 20mA) Intrinsically Safe Pressure Transmitters HR-K intrinsically safe pressure transmitter with intrinsically safe circuits for explosion hazardous areas, explosion-proof grade Exd ⅡBT4, technical performance indicators and common type pressure transmitter the same device. In the system circuit must be shielded signal cable, and grounded. Intrinsically safe measuring system diagram (4 ~ 20mA) Mounting HR-K series pressure transmitter usually direct pipeline installation, install a valve, easy installation, commissioning and maintenance. When the medium temperature is higher than 85 ℃ will need to install a certain length of impulse piping for cooling medium, otherwise it will cause damage to the transmitter measurements are not allowed to even. Direct pipeline installation accessories user can be based on fixed and fixed-site environmental requirements, with a wall fitting or pipe fittings. Wall fixing screw M5 2- B3 1- M8 expansion screw fixing B1 vertical pipe rack frame fixed horizontal tube type B Dimensions Dimensions K1 - K2 technical performance and Dimensions Specifications Power: 24V · DC; no load transducer It can work in 12V · DC, max 40V · DC.
