汉森压力传感器 PT100C 说明书
8PT100cMAY 2011CAUTIONThe Hansen Pressure/Temperature Transducers are for refrigeration systems only. These instructions and related safety precautions must be completely read and understood before selecting, using, or servicing these transducers. Only knowledgeable, trained refrigeration technicians should install, operate, or service these transducers. Stated temperature and pressure limits should not be exceeded. Transducer bodies should not be removed from the system unless the system has been evacuated to zero pressure. Escaping refrigerant can cause injury, especially to the eyes and lungs.WARNING : As with all electronic and mechanical components, there is a limited product life expectancy. An expected life of seven to ten years is typical. This should be understood as only a suggested replacement time period. Actual condition and performance of electronics due to ambient conditions, quality of electrical current, voltage, etc., may necessitate a dif ferent replacement schedule. Regardless, transducers should be inspected at least once a year to ensure their safe and continuous service. See also Safety Precautions in the current List Price Bulletin and the Safety Precautions Sheet supplied with this product.TROUBLESHOOTING GUIDEThe Pressure/Temperature Transducers are simple, solid-state devices. In the event that a problem should arise, the following guidelines should be followed for troubleshooting the probe.M ake sure that the actual conditions match the calibration conditions. The refrigerant that the probe is calibrated for is ammonia, unless a refrigerant key is plugged into the circuit board. The refrigerant type is stamped on the key.It is very important to prevent moisture from entering the transducer housing at all times. Take steps to ensure that the internal electronics stay dry during storage, installation, and operation. Moisture inside the probe housing can damage the transducer electronics.ORDERING INFORMATIONREFRIGERANTCATALOG NUMBERSTANDARD -35ºF to +150ºF (-37ºC to +65ºC)LOWTEMPERATURE -60ºF to +150ºF (-51ºC to +65ºC)Ammonia HPT717HPTL717R22HPT22HPTL22R134a HPT134HPTL134R404A HPT404HPTL404R507A HPT507HPTL507Propane HPT290HPTL290CO 2HPT744HPTL744TO ORDERSpecif y catalog number.

如何在高温环境下使用压力传感器？
如果测量介质的温度在70到80℃，则只需要在压力传感器或者压力表与取压连接处加一个散热器，这样可以让温度适当降低一点，让介质通过散热器散热后与仪表直接接触，
如果测量介质温度超过100℃，最高到达200℃的时候，我们就需要在取压口安装冷凝圈后再加散热器，这样介质通过冷凝圈冷却后，再通过散热器散热与压力传感器直接接触时温度就很低了。
在测量温度超高的场合使用，可以将导压管延长后接压力传感器，也可以加毛细管后安装散热器来达到介质冷却的效果。

高精度高温型压力传感器安全操作及保养规程
高精度高温型压力传感器安全操作及保养规程前言高精度高温型压力传感器是工业自动化领域的重要设备，主要用于实时测量生产过程中的流体或气体压力变化。
为了确保设备的高效、稳定运行，需要按照安全操作及保养规程进行操作和维护。
安全操作规程1. 软件调试在进行软件调试前，需要确保传感器与其他设备连接正确、电源稳定等。
在软件调试过程中，需要注意以下几点：•确保程序正确地读取了传感器测得的压力值。
•确保程序能够准确地转换压力值，并在显示屏或其他设备上显示。
•确保程序能够确保压力值在规定范围内变化，并及时做出响应。
2. 硬件操作在使用传感器进行硬件操作时，需要注意以下几点：•仅能使用制造商推荐的电缆和电源连接。
未经授权使用的电缆和电源可能会引起传感器损坏、设备故障等问题。
•传感器表面应经常用干燥软布擦拭，以防止沾染灰尘、油垢等杂质。
3. 传感器安装在安装传感器时，需要注意以下几点：•确保传感器可以正常连接到生产过程中需要测量压力的设备上。
•传感器应正确地安装在任一测量点上，这是确保仪器稳定性和准确性的关键因素之一。
•需要遵循制造商为传感器规定的安装操作流程，保证传感器安装正确。
4. 清洗传感器在定期维护时，需要清洗传感器。
清洗传感器之前需要拆卸传感器并关闭电源。
然后在干燥环境下使用软布清洗传感器，确保清洗彻底，并在装配传感器之前，检查其是否有损坏或松动。
保养规程1. 定期校准为了确保传感器的准确性，每隔一定时间需要对传感器进行校准。
制造商一般会制定校准方案，根据实际情况进行校准。
如果校准不当可能会导致仪器准确度降低。
2. 储存温度在储存传感器时，需要选择标准的环境条件，避免传感器损坏、变形、磨损和失真。
标准的环境温度范围为15度至40度。
为了保持适宜的操作条件，需要尽可能地避免传感器与水、蒸汽、油、粉尘和化学品接触。
总结正确、安全、稳定地操作和维护高精度高温型压力传感器，可以最大化地提高生产效率。
如果按照安全操作和保养规程进行操作和维护，可以使传感器拥有更长的使用寿命，同时保持精度和可靠性。

高温高压屏蔽电泵隔热屏隔热计算方法及分析
高温高压屏蔽电泵隔热屏隔热计算方法及分析作者：张志莉来源：《科技创新与生产力》 2015年第11期张志莉（佳木斯电机股份有限公司，黑龙江佳木斯 154002）摘要：文中以某型高温高压屏蔽电泵产品为例，进行隔热屏隔热能力计算分析，为该类产品隔热能力设计提供计算方法。
隔热屏设计可降低高温区热量向屏蔽电动机部分的传递速度，延长轴承使用寿命，提高该类产品可靠性、安全性。
关键词：高温高压；屏蔽电泵；隔热屏中图分类号：TH38文献标志码：ADOI：10.3969/j.issn.1674-9146.2015.11.115收稿日期：２０15－04－22；修回日期：２０15－08－23作者简介：张志莉（1984-），女，黑龙江五常人，工程师，主要从事屏蔽电机的设计研发研究，E-mail：zzl19840102@。
目前，国内高温高压屏蔽电泵设计温度一般350 ℃左右，设计压力35 MPa左右，运行温度320 ℃左右。
高温高压屏蔽电泵一般由屏蔽电动机部分、泵部分及隔热屏等结构组件构成，作为屏蔽电泵的重要组成部分，隔热屏占有很重要的地位。
隔热屏主要作用是将泵部分的高温隔离，避免高温介质直接进入电机腔，由于屏蔽电泵是泵腔与电动机腔相联通的无密封泵，实质上隔热屏更重要的作用是降低泵部分热量向屏蔽电动机部分的传递速度。
泵部分的热量首先通过隔热屏传递到电机腔的一次循环水，再通过二次冷却水与一次水进行热交换的作用，保证在单位时间内将泵端传递过来的热量通过二次冷却水带走，达到机组的热平衡，从而保证电动机温升稳定在允许范围内。
通常根据屏蔽电动机定子绕组的耐热等级要求或水润滑石墨轴承的允许工作温度，需要保持电动机端的介质温度小于100 ℃，根据此边界条件，采取传统方法或有限元分析法，对已设定尺寸的隔热屏的隔热能力进行计算分析，以此作为产品设计的手段，提高产品设计的准确率，保证机组的安全性、可靠性。
1 隔热屏结构简介根据屏蔽泵的发展历程，应用比较早的是水冷隔热屏结构，但隔热屏腔内需要通入冷却水，结构较复杂；现多数屏蔽泵隔热屏采用空气隔热结构，主要分为单层空气腔隔热结构、多层空气腔隔热结构、缩颈式隔热结构等形式。
