Model 508B1.1DEFINITION/APPLICATIONModel 508B is a signal powered, two-wire current-loop indicator that accepts 1-5 mA,4–20mA, or 10-50 mA process signals and digitally display (±2000 active counts) the process variable in either percent or in engineering units for such parameters as pressure, flow,temperature, and level.1.2FEATURESIn-field ProgrammabilityInput ranges (1-5 mA, 4-20 mA, or 10-50 mA) are selected by push-on jumpers. Three decimal points and a dummy right-hand zero may also be selected by push-on jumpers. Zero and span may be fine tuned with precision, 25-turn potentiometers. Positive slope response may be changed to negative slope response (e.g. , +6000 to –18000) by simply changing two other push-on jumpers.(.078)Signal PoweredModel 508B obtains operating power directly from the current loop, requiring a drop of lessthan 2.5 V or 2.5 mW at 1 mA.Electrical Isolation/Overrange ProtectionThe 508B is electrically isolated from its case and is immune to most sources of electricalnoise encountered in process-control environments. In the event of input overrange currents, the 508B can tolerate 250 mA in the forward direction and 1000 mA reverse.Vibration/Shock/Water ResistanceLow mass and multi-point circuit board support give excellent vibration and shock resistance.Sturdy, die-cast construction, polyurethane paint,and full fluorosilicone gasketing ensure avirtually waterproof case.Circuit boards are conformally coated for added humidity protection.Mounting VersatilityThe 508B-1 may be mounted in a control room on either American or European relay tracks with snaptrack adaptors. The unit can be wall mounted using an available bulkhead adaptor or mounted in an explosion-proof enclosure for wiring compatibility with other equipment in hazardous environments.Both the 508B-2 and the 508B-3 may be connected directly to a conduit with a "T" junction box.2.0SPECIFICATIONS2.1INPUTCurrent:1-5 mA, 4-20 mA, or 10-50 mA(jumper selectable)Voltage drop: 2.5 V max forward; up to 50 mAProtection:250 mA forward at 3 V or 6 V with IS option;1000 mA reverse at 2.5 VZero range:–2510 to +2000 counts; jumper selectable in 4 overlappingcoarse ranges with a 25-turn potentiometer for continuousadjustment within the following selected ranges: –2510 to–1420; –1580 to –420; –470 to +850; and +760 to +2000.Span range:0 to 2000 counts, continuously adjustable with 25-turnpotentiometerNormal mode rejection:46 dB min at 50/60 HzCommon mode rejection:120 db typical, dc to 60 HzCommon mode voltage:700 V peak from dc to 60 Hz (meter to case)RFI susceptibility:Less than ±0.5% of span at a distance of one meter from a2-watt, hand-held transceiver (approximately equivalent to10 V/m field strength) at frequencies of 27 MHz or 440 MHzNOTE: Proper lead dress and shielding required.2.2ACCURACYAccuracy:Within ±0.1% Span ±1 Count at +25°CZero Tempco:±0.1 Count/K typ. , ±0.2 Count/K max.Span Tempco:±0.005% Span/K typ. , ±0.015% Span/K max.2.3DISPLAYType:7-segment LCD, 8.9 mm (0.350 in) highColor:Black digits on white backgroundSymbols:–1.8.8.80Polarity:Minus signOverrange:Three least significant digits blankedExtra digit:Dummy right-hand zero is jumper selectableDecimal points:Three positions, jumper selectableLifetime:More than 30,000 hours to 2:1 contrast ratioTemperature derating:2:1 lifetime reduction for each 10°C above 60°CHumidity derating:2:1 lifetime reduction for each 10%RH above 60%RH2.4CONVERSIONTechnique:Dual-slope, average-value with autozero correctionPolarity:Determined automatically at the end of signal integrationperiodSignal integration period:100 mS typ.Reading rate: 2.5/sec2.5ENVIRONMENTALTemperature:-40 TO +85°CHumidity:To 95% at 40°CVibration: 1.52 mm (.06 in) double amplitude, 10-80 Hz cycledShock55 g, half-sine, 9-13 msec durationWater resistance Watertight to a proof pressure of 35 kPa (5 psi)Mounting position:Any2.6MECHANICALWeight:400 g (14 oz)Diameter:74 mm (2.9 in)Height:48 mm (1.9 in) including barrierElectrical connections:Standard: 3-position barrier strip with #6 screw wire clampsOptional: Two #18 stranded wires, 305 mm (12 in) long3.0MECHANICAL ASSEMBLY AND INSTALLATION3.1SAFETY CONSIDERATIONSTo ensure safe operation follow the guidelines below:VISUAL INSPECTION: Do not attempt to operate the instrument if damage is found.This instrument will meet the requirements of certain FM safety certifications for hazardousenvironments.

六、在曲面上测量
测量圆柱或圆形边缘时，可以利用仪器测嘴上的 V 型口，如 图（5）所示。测量凹面时与测量平面相同，但要注意最小曲率的 限制。
图5
七、在粗糙表面测量
在粗糙表面测量时，读数将增大（特别是在颗粒尖上）。 在特别粗糙（如峰值超过50um 的钢基体上，并且涂层厚度超过 100um 时，实际读数高于涂层真实厚度达20％之多。在这种情况 下应至少测量6 次以上，得出平均值。
E01
◆ 测厚仪放置错误
◆ 在被表面正确放置测厚仪进行测量
◆ 基体是永久磁钢 E02 错误的测量
操作错误
◆ 消除基体磁性 重新测量
E04 ◆ 覆层厚度高于测量上限 E05 ◆ 测厚仪没有正确在放在表面上测量
◆ 选择合适的仪器 ◆ 在被表面正确放置测厚仪进行测量
◆ 基体没有磁性 E06 电池电量低 E00
被测量件的曲率对测量有影响，一般凸面造成测值偏大，凹 面则偏小。尽管仪器在设计时对这方面有所补偿。 e、覆盖层的厚度
测厚精度随覆层厚度变化面变化。对于薄的覆层，其测量精 度是一个常数，与覆层厚度无关；对于厚度的覆层，其精度与覆 层厚度近似成正比。 f、剩磁
基体金属的剩磁对 Mikrotest 测厚仪的测量结果会有影响。 g、磁场
五、请按照使用说明正确使用，如发现异常，请停止使用并与 沧州欧谱公司联系。
SONOTEK原理
雾化过程超声波喷嘴利用高频声波（超出人类声觉范围）产生雾化功能。
盘片状压电式陶瓷换能器接收来自“思诺泰” 宽频超声波发生器的高频电能（请参阅第11页），并把它转化成同样频率的振动机械运动，这与换能器偶合一起的两个钛质柱筒将机械振动增强。
换能器化成的激荡产生沿喷嘴长度方向的持续声波，声波的波幅在达到雾化面时最大，这是位于喷嘴最前端的细小直径部位。
一般而言，高频喷嘴尺寸较小，产生的雾滴也较小，同时较低频喷嘴的流量低些（请参阅第9 页的流量表）。
液体通过喷嘴全长的一个大而无堵塞通道导入至雾化面。
出现在雾化面的液体吸收了振动能量，因此而雾化。
结构典形喷嘴本体由钛材料制成，因其具有突出的声学特性、高抗拉强度和极好的抗腐蚀性。
保护外壳则以316不锈钢制成(亦可选择钛)。
功率控制振动幅度必须仔细控制，在低于被称之为临界振幅的情况下，便没有足够能量来产生雾化。
但如果振度太高，液体会被撕裂，并以块状被喷出。
只有在一个很窄的输入功率范围内的理想幅度方能产生这种喷嘴独特而细微的低速喷洒。
输入能量的水平是用来区分超声波喷嘴和其它超声波设备，如超声波焊接机、超声波乳化器及超声波清洗机。
那些超声波设备所依靠的工作功率通常要几百、几千瓦，但对于超声波雾化而言，输入功率水平一般从1 至15 瓦就足够雾滴大小的分布在以超声波来雾化时，雾滴的大小是由喷嘴的振动频率、雾化液体的表面张力和密度来决定的，其中频率是决定因素，频率越高，雾滴大小中位数直径越小。
一般而言，超声波喷嘴产生的雾滴大小分布情况是遵循对数－常态曲线的，是一个在对数尺上类似钟形的曲线，下图表显示在不同频率下以水为介质的雾滴大小累计分布情况。
有几个参数可描述雾滴特定分布的平均及中位数，雾滴数目中位数直径是指雾滴大小的50%点，也就是雾滴数目中有一半的直径大于这个值而另一半小于这个值。
雾滴数目平均直径和体积平均直径都是平均直径，数目平均直径是指把一个喷雾样本中所有雾滴的直径相加除以雾滴的数量，体积平均直径是指把一个喷射样本中所有雾粒的体积相加（体积与直径的立方成正比），取其立方根，再除以雾滴的数量。

电磁炉用功率管的型号 代换 参数
电磁炉用功率管的型号代换参数2007年07月28日星期六 12:05大量维修实践表明，电磁炉（灶）内的部分元器件因工作温度较高，工作电流较大，电压较高等，其故障或损坏概率也较高。
其中的场效应功率管损坏率最高。
但由于商业竞争激烈，一般都不随机附带图纸，加之电磁炉所采用的场效应功率管一般均为较新产品，这便给维修带来不便和困难。
下面笔者根据汇集来的相关资料，提供几种常用电磁炉场效应功率管及代换资料供参考。
电磁炉一般均采用N型沟道功率场效应管，其相关参数为BVCBO≥1600V，BVCEO≥1000V，PCM≥100W，ICM≥7A，HFE≥40。
常用的电磁炉用场效应管内部带阻尼二极管的型号有 GT40N150D、GT40T301、SEC·G40N150D、ZON120ND、GT40T101、SQD35JA等。
内部不带阻尼二极管的型号有BT40T101、SGL40N150/150D等。
在维修代换时，若采用不带阻尼二极管的功率场效应管，应在D、S极间加接一只阻尼二极管，该二极管必须是快恢复型阻尼二极管，其耐压应≥1500V。
加接时正极接S 极，负极接D极即可。
参考型号如S5J53、 BY4591500等。
在负载电磁线圈和功率管之间串一只100W的灯泡再通电试机,可以防止烧管。
GT40Q321，FGL40N150D， FGL60N170D， FGA25N120，SK25N120，G40N150D， FGA25N135，1MBH25D--120，GP20B120UD--E，IXGH20N120BDI，以上功率管内部都带阻尼管，耐压都在1200V以上电流在20A以上只要电流相差不多都可以互相代换。
SGW25N120，K15T120。
以上的管子内部不带阻尼，如果要代换一上功率管时可以在电路板上安装2个以上的阻尼二极管耐压1200V以上，电流在8A以上。
电磁炉的关键元器件介绍1、大功率管IGBT（H20T120）说明：（1）、IGBT为电磁炉电路控制核心元器件，使用温度为小于85℃。
