Product Description: Use the object of liquid, gas, or steam.The measurement range is 0-0.125 to 1.5 kPa (0-12.5 to 152 m m H 2 O) with an output signal of 4 to 20 mA dC power supply of 24V dC, and the transmitter works at 12VdC, up to 45V dC.Load characteristics: working principle: Product characteristics: structural parameters: the table scale is 45mm long; the accuracy level 2.5.ds RⅡ BT5 is installed in dangerous places with level 0.5 digital indicator accuracy; this safety type laⅡ CT5; (see explosion-proof type 1151 transmitter manual for details) measuring range and zero point external continuously adjustable; positive and negative migration shall not exceed the measuring limit after positive and negative migration.Maximum positive migration to minimum adjustment range of 500% maximum negative migration to minimum adjustment range of 600% temperature range amplifier working at-29~93℃ sensitive element working at-40 to 104℃ storage temperature-50 to 120℃ static and overpressure cutoffs on either side or side of the transmitter plus 0 (absolute pressure) -6.89MPa transmitter is not damaged.The transmitter can operate between a static pressure of 3.5kPa (absolute pressure) and 6.89MPa; the relative humidity of 0-100% volume variation of less than 0.16cm3 damping time constant is continuously adjustable between 0.4-4.0S.Start time 2S, no preheating.Technical indicators (vertical installation, range 0-0.25~1.5.kPa, no migration, under standard conditions).0.5% of soil with precision calibration range. Integrated errors including linear, variation and reproducibility.The insensitive zone instability does not exceed 0.5% of the maximum range of the ± within six months.Temperature impact maximum range 0-1.5 kPa zero point error: ± l% / 28℃ of the range.Total error: ± 1.5%mp ℃ of the range.static pressure affects zero error: 6.89MPa static pressure. Error is ± 1.0% range error: error is-1.75±0.75/%6.89Mpa Scale error is a systematic error that can be corrected in advance before installation.Vibration affects on an arbitrary axis with a frequency of 200Hz, resulting in an error of ± 0.05% / g of the maximum range.Power supply impact output changes are less than 0.005% / V.The load has no load impact on power supply stability.Installation location impact. When the measurement diaphragm is not vertically installed vertically, a zero error is less than 0.25kPa, but has no effect on the range, which can be corrected and eliminated.Structural index structural material isolation diaphragm and exhaust / exhaust valve: 316 stainless steel flange and joint: 316 stainless steel contact medium O type diagram: fluorinated rubber filling liquid: silicone oil bolt: carbon steel galvanized amplifier housing: low copper aluminum alloy coating: polyester epoxy resin.The two flanges are connected to 1 / 4-NPT, 54mm (218 "), 1 / 2-NPT, and 51,54,57mm (2", 218 ", 214").The l / 2-NPT thread end wire pipe and micro incense for electrical connection
