Adjustment of Setpoin Note – As indicated below, adjustment of setpoint is made by use of 7⁄8˝ nut. Precision switch element mounting screws and bracket adjusting screw are factory sealed and should not be tampered with.B700 Series – A single setpoint adjustment nut (7/8˝) is located centrally at the bottom on the inside of the enclosure.For accurate setpoint calibration, mount the switch on a calibration stand, a pump or catalog No. 1305 deadweight gauge tester. A suitable reference standard such as an ASHCROFT Duragauge or Test Gauge is necessary to observe convenient changes in pressure.As received, the pressure switch will normally be set to approx-imately 90% of the indicated range. Pressurize the s ystem torequired setpoint and turn the adjustment nut until switch changes mode. Direction of turning is indicated on a label affixed to the inside of the switch enclosure. When setpoint has been achieved raise and lower pressure to insure that setpoint is correct.After installation of the switch replace cover to insure electrical safety and to protect internal parts from the environment.Note – Since vacuum models are already above setpoint at atmo-sphere, the Normally Open (NO) circuit will be closed as received.D700 Series – A single setpoint adjustment nut (7/8˝) is located centrally at the bottom on the inside of the enclosure.The direction of turning is indicated on a label affixed to the inside of the switch enclosure.A typical calibration procedure would be as follows: Static Working Pressure - 600 psig Adjustable Differential Range - 5/200 psid Differential Setpoint - 150 psi above static working pressure.Simultaneously raise the high and low side pressure to 600 psig. Maintain the low side pressure at 600 psig. Raise the high side pressure to 750 psig to obtain 150 psi differential.Turn the adjustment nut until the switch changes mode at 150 psi differential. When the setpoint has been achieved, raise and lower the high side pressure to ensure that the differential setpoint is correct.D700 Series (low range differential) – A single setpoint adjust-ment nut (7⁄8˝ ) is located centrally at the bottom on the inside of the enclosure.The direction of turning is indicated on a label affixed to the inside of the switch enclosure. XG5 switches have a setpoint indication scale adjacent to the adjustment nut. To adjust the switch, align the top of the adjustment nut hex with the indicator line on the scale. Do not force adjustment or attempt to ex-ceed the maxi-mum setting shown on the scale or nameplate.For accurate setpoint calibration or for switches without a scale mount the switch on a calibration stand so that the HIGH and LOW pressures expected under operating conditions may be obtained. Suitable reference standards are necessary for each pressure.Note – During calibration an approximate setpoint under operating conditions can be obtained by setting the operating point with the low side open to atmosphere. A final setpoint adjustment can be made after installation.Apply LOW pressure. Then apply HIGH pressure to the required setpoint and turn the adjustment nut until the switch operates. When the setpoint has been achieved, raise and lower HIGH pres-sure to ensure that the differential pressure between the HIGH and LOW pressures is correct.After installation of the switch, replace the cover to ensure electri-cal safety and to protect the internal parts from the e nvironment.T700 Series – A single setpoint adjustment nut (7⁄8˝ ) is located cen-trally at the bottom on the inside of the enclosure.The bulb of the switch should be immersed in a bath at the desired setpoint temperature. Optimum performance will be obtained if the bulb is fully immersed. Allow five minutes for initial stabilization.As received, the temperature switch will normally be set to approx-imately 90% of the indicated range. After stabilization, turn the adjustment nut until switch changes mode. Direction of turning is indicated on a label affixed to the inside of the switch enclosure. When setpoint jas been achieved raise and lower temperature to insure that the setpoint is correct.After installation of the switch replace cover to insure electrical safety and to protect internal parts from the environment.B750, D750 and T750 Variable Deadband Switches – Deadband is varied by rotating the wheel on the precision switch. Whenviewed from the front of the enclosure, rotation to the left increases deadband – rotation to the right decreases deadband. Letters on the wheel may be used as a reference. Deadbands obtainable will vary from 0.5% to 9% of pressure or temperature range depending on range segment and type of diaphragm.Adjustment of Setpoint – As received, the switch will normally be set to approximately 90% of range. Rotate the wheel on the MICRO SWITCH all the way to the right; this will provide small-est deadband. Pressurize, or increase bath temperature, to the required setpoint and turn the adjustment nut until the switch changes mode. Lower the pressure to reset the switch. Rotate the wheel on the MICRO SWITCH until the desired deadband is obtained. The upper setpoint will be changing upward with this adjustment. Lower the pressure to reset the switch. Then increase the pressure to the desired setpoint and turn the adjusting nut until the switch changes mode. Lower the pressure and check reset-point and deadband.6. Specific Conditions of Use • P rior to use, the equipment shall be subjected to a pressure test, which shall be based on the process pressure of the associated system. If available, the test shall be conducted in accordance with the requirements of an applicable industry standard. The pressure shall be applied from the system side of the diaphragm. It must be proven that there is no leakage of the test medium into the flameproof enclosure and that the flameproof enclosure does not become pressurized above ambient atmospheric pressure.• E poxy coated enclosures are non-conducting and may generate an ignition-capable level of electrostatic charges under certain extreme conditions. The user should ensure that the equipment is not installed in a location where it may be subjected to external conditions (such as high-pressure steam) which might cause a build-up of electrostatic charges on non-conducting surfaces. Additionally, cleaning of the equipment should be done only with a damp cloth. • S witch vent must not be used nor blocked.• I n accordance with clause 5.1 of IEC/EN 60079-1 the critcal dimensions of the flamepaths are:• Never use aggressive solvents.• Do not use high-pressure water to clean the switch.8. Maintenance/Troubleshooting• All ASHCROFT switches require little or no maintenance.• I nspection and maintenance of this equipment shall be carried out by suitably trained personnel in accordance with the applica-ble code of practice e.g. IEC/EN 60079-17.• Be sure that the case is closed at all times.• W hen the switch is exposed to process media that may hard-en and/or build up in the pressure port, the switch should be removed and cleaned as needed.• I f the switch does not function, only trained and skilled personnel should check on the wiring, power supply and/or mounting.• I f the problem cannot be solved, do not attempt to repair, please contact Ashcroft or Ashcroft distributor.© Ashcroft Inc., 250 East Main Street, Stratford, CT 06614 USA, Tel: 203-378-8281, Fax; 203-385-0408, All sales subject to standard terms and conditions of sale. b-d-t-700_switch_im_RevC_(009-10120-ATEX) 11-05-18。

BS系列高强钢简介Brief introduction开发历史工程机械用系列高强、超高强结构钢是宝钢于2000年在国内率先开发成功的一类热轧新产品，牌号大多采用“BS”开头，如第一代高强钢BS600MC和BS700MC已大量应用于工程机械、集装箱制造等行业。
2005年宝钢开发成功具有优良低温韧性的第二代高强钢，牌号为BS700MCK2、BS600MCJ4、BS550MCK4等等。
BS系列高强钢为低碳低合金结构钢，具有良好的可焊接性和冷成形性，可广泛应用于工程机械、车辆结构、集装箱等制造行业。
高强钢BS系列高强结构钢采用宝钢股份公司先进的冶炼技术、铌钛微合金化处理以及精确的控制轧制和控制冷却技术获得金相显微组织为少量铁素体加针状体组织。
制造工艺和金相组织保证了合格稳定的力学性能、加工性能和可靠的质量。
自从2000年开发成功以后，深受用户青睐，产销量逐年增加。
超高强钢选用高强钢代替传统产品可显著减小钢板的设计厚度，进而减轻结构的自重。
除此之外，BS系列高强钢还具有如下特点：• 优良的成形性，不同强度级别钢板均能够冷加工成形；• 良好的焊接性，钢板具有低焊接裂纹敏感性，焊接接头的性能优良；• 良好的低温冲击韧性。
制造工艺及交货状态生产工艺流程：BS系列高强钢采用氧气转炉冶炼镇静钢，经过二次精炼后进行连续铸造，连铸坯送热轧厂再加热并采用控轧控冷工艺轧制成卷，精整检验后可以钢卷状态交货，也可以矫直切板后以钢板状态交货。
交货状态：BS系列高强钢基本采用轧态（TMCP）交货。

证明BS系列高强钢在0℃以上进行各种焊接加工时，不易产生焊接裂纹。
—接头的硬度BS高强钢焊接接头的最大硬度小于HV350。
高强钢的焊接热影响区存在一个比较窄的软化区。
建议尽可能采用小热输入、快速焊接为宜，以减小软化区的宽度。
焊接工艺参数环境温度大于0℃时，BS高强钢板不需预热就可直接进行焊接，不易产生焊接冷裂纹。
推荐使用MAG焊接，推荐焊接保护气体为80%Ar+20%CO2；气体流量18~25 l/min。
对于推荐的焊丝适用于全位置焊接，当垂直位置焊接时，推荐采用上向焊接方法，这样可避免焊接缺陷产生。
热轧高强钢适用于多种接头型式的焊接，常用的接头型式有：对接接头、角接接头和搭接接头；常用的坡口型式有：I型坡口，V型坡口和双V型坡口型式。
在焊接时，若出现未焊透时，应检查是否间隙太小，是否电弧没有垂直钢板表面。
对于打底焊时，可采用较小焊接参数的熔滴过渡形式，即小电流，小电压，快速焊；对于特别重要的结构件，也可考虑采用TIG焊打底。
对于定位焊接，为了防止出现裂纹，应保证一定的焊接长度，至少大于50 m m长，焊接参数可选用稍大一些的熔滴过渡形式。
对于M AG焊，以常用焊丝规格φ1.2m m为例，典型打底焊的焊接参数为：100~200A，12-19V，2.5~7mm/s；典型的定位焊焊接参数为：200~250A，20~23V，4.0~6.5mm/s。
对于填充和盖面焊接，可以采用稍大一些的熔滴过渡和射流过渡形式的焊接工艺。
对于M AG焊，以常用规格φ1. 2 m m为例，推荐的典型填充和盖面焊接工艺为：2 0 0~25 0A，2 0~23V，4.0~6 . 5 m m /s（熔滴过渡）或270~320A，27~32V，4.0~6.0mm/s（射流过渡）。
焊接及其它应用性能6工程机械用高强度热连轧结构钢High Strength Cold Forming Hot-rolled Steel焊接材料在接头力学性能满足构件要求的情况下，BS高强钢的配套焊接材料应尽可能选用强度级别稍低的焊接材料，避免高匹配焊接材料的选用。
