在控制器中仅引入“比例”项往往是不够的，比例项的作用仅是放大误差的幅值，而目前需要增加的是“微分项”，它能预测误差变化的趋势，这样，具有比例+微分的控制器，就能够提前使抑制误差的控制作用等于零，甚至为负值，从而避免了被控量的严重调。所以对有较大惯性或滞后的被控对象，比例+微分(PD)控制器能改善系统在调节过程中的动态特性。本机免费保修年在质保期内，公司可向客户工厂，随时派驻技术员对客户所购买的设备进行检查并对设备的使用进行指导，质保期结束后公司服务人员将定期访问客户工厂，对发现的问题，给客户管理部门作出书面报告以便修正。的系统均采用英国WEST或者日本富士温控仪表，进口电器元件，体成型工艺，运用PID自整定智能控温技术，控制可达±1℃左右温度，控制在使用的温度范围内，加热主电源采用固态模块无触点开关电路，适应频繁开关。注塑机模具控温生产温度控制设备和提供温控解决方案的服务型企业，是封闭循环供热与大气相通，可延长控温设备的使用寿命，液相输送热能，热损失小，节能效果显著，环保效果好。智能全自动控制温度、恒温保护、加热温度控制在±1℃，且加热功率可从20%到任调，从而保证该装置完全达到用户要求。并具有多重保护和可靠监控装置、并可与计算机连网，实现人机对话。应用亚克力板材加温、橡塑、印染、化工、注塑，挤出橡胶，压铸模具，反应釜，层压热压机，碳纤维新材料、无纺布热轧机、SMC玻璃钢、模具等需热行业，南京科洛德精机的注塑机模具控温温控器控制仪表箱内的维持温度，当达到维持温度时，温控器切断电源，电加热器不再加热，避免加热器的表寐度接近温度等级的允许温度。
