Unpacking InstructionsRemove the Packing List and verify that you have received all equipment, including the following (quantities in parentheses):OMNI-AMP Thermocouple Amplifier (1) Operator’s Manual (1)If you have any questions about the ship-ment, please call the OMEGA Customer Service Department.When you receive the shipment, inspect the container and equipment for signs ofNote any evidence of rough handling in transit. Immediately report any damage to the shipping agent.The carrier will not honor damage claims unless all shipping material is saved for inspection. After examining and removing contents, save packing material and carton in the event reshipment is necessary.The OMEGA®OMNI-AMP thermocouple amplifier is designed to boost small thermocouple signals up to 100 times. The OMNI-AMP amplifies the millivolt signal generated by a thermocouple (almost always less than 75 millivolts), and drives meters or readouts that are not sensitive enough to be driven directly by the small output of the thermocouple. There may be a temptation to use the sensitive amplifier to drive a second microvolt amplifier in order to achieve even higher gains. However, the inherent noise of the combined system will rule out such use. OMNI-AMP Amplifier is ideally suited for driving millivolt meters where the full scale range is not more sensitive than 100 millivolts without further amplification. For example, when used with a meter having a full scale reading of 100 millivolts and OMNI-AMP Amplifier set at the 100 gain position, the full scale reading of the meter will represent 1.0 millivolt source voltage. This corresponds to 77°F using a Type K, CHROMEGA®-ALOMEGA® thermocouple wire, referenced at 320°F. See the OMEGA Complete Temperature Measurement Handbook and Encyclopedia®which contains Temperature-EMF tables for thermocouples.Keep in mind, when working with positions, shielding and grounding of the input and output leads is important. Be sure to observe the proper thermocouple input polarity. Note that the output range of your OMNI-AMP Amplifier is - 1.5 to+2.0 Vdc. Thermocouples are used in the range of -450°F to +5000°F and the output signals from them range from -10 millivolts to +80 millivolts. Thus, your OMNI-AMP Amplifier is ideally ranged and designed for them.It is recommended to try using lower gain settings first and use no greater gain setting than is required. When a gain setting of one (unity)is used, zero adjust is inoperative. If a small offset EMF is present, it is recommended that the zero adjust on the readout device be used to bring the instrument to zero. For example; all panel meters have an adjusting screw to set the pointer. When using unity gain, it is only necessary to turn this adjusting screw slightly to reset the meter. Use the zero adjust on the amplifier for all other gain settings.Your OMNI-AMP Amplifier can drive both high and low impedance devices. Most meters and readout devices have high impedance; i.e., over 1,000 ohms. Withsuch meters, it is generally best to operate the OMNI-AMP Amplifier as a constant voltage device. With OMNI-AMP II Amplifier, this is achieved by placing the mode switch in the volt/volt position. In the case of the OMNI-AMP I Amplifier, it is set for constant voltage mode when it leaves the factory. Certain pyrometers are low impedance devices having a circuit resistance of only a few ohms. In such cases, the OMNI-AMP Amplifier should be operated as a constant current device. With OMNI-AMP II Amplifier, simply place the mode switch in theMA/VOLT position. With OMNI-AMP I Amplifier, it is necessary to remove the cover plate and throw the small internal switch to the position suggested in the instructions on the side of the OMNI-AMP Amplifier.Your OMNI-AMP Amplifier has been designed to have an extremely low dc drift as a function of time and temperature. However, if your application is to amplify signals which are in the region below five millivolts, you will enhance the already low drift characteristics of this instrument by first allowing a 15-minute warm up period, and then by maintaining the temperature of the OMNI-AMP Amplifier as constant as possible.Note: OMNI-AMP IIB Amplifier with reference junction. This unit contains a selfcompensating electrical bridge network incorporating a temperature sensitive resistance element that is powered by a 3.6V lithium battery to ensure a reference junction at 0°C or 32°F. Be certain that the thermocouple used in conjunction withOMNI-AMP IIB Amplifier is of the calibration designated on the input connector.Important considerations when using your OMNI-AMP Millivolt Amplifier Before using an OMEGA®OMNI-AMP millivolt amplifier, please check your recorder, meter or oscilloscope for the following:1. If you are using an oscilloscope and ithas a sensitivity of 1 millivolt/centimeter or better (500 microvolts/centimeter, 100 microvolts/centimeter), then OMNI-AMP Amplifier SHOULDNOT BE USED as it will not amplifyyour thermocouple EMF withoutexcessive noise. If your oscilloscopehas a sensitivity of less than 1 millivolt/ centimeter (500 millivolts/centimeter, 1volt/centimeter, etc.), then your OMNI-AMP Amplifier will be quite helpful inboosting the oscilloscope sensitivity.Keep in mind that the lower the gain or sensitivity of the oscilloscope, thehigher the useful gain of your OMNI-AMP Amplifier.2. If you are using a meter which has afull scale sensitivity of 10 millivolts orbetter (500 microvolts full scale, 100microvolts full scale, etc,), then yourOMNI-AMP Amplifier SHOULD NOTBE USED as it will not be able toamplify the EMF without excessivenoise. If your readout meter has asensitivity of less than 10 millivolts full scale; i.e,1 volt full scale, then yourOMNI-AMP Amplifier will be veryhelpful in boosting the meter’ssensitivity. Keep in mind that the lower the gain or sensitivity of the readoutmeter, the higher the useful gain ofyour OMNI-AMP Amplifier.3. If you are working with an oscillographrecorder and it has a sensitivity of 1millivolt/centimeter or better, then theOMNI-AMP Amplifier should not beused as it will not be able to amplify the EMF without excessive noise. If youroscillograph recorder has a sensitivity of less than 1 millivolt/ centimeter, then your OMNI-AMP Amplifier will be very helpful in boosting the oscillographrecorder’s sensitivity considerably. As with meters and oscilloscopes, keep in mind that the lower the gain orsensitivity of the oscillograph recorder, the higher the useful gain of yourOMNI-AMP Amplifier.4. The OMNI-AMP Millivolt Amplifier isNOT RECOMMENDED for use withdigital readout meters unless themaximum sensitivity is1 millivolt. In any event, if a decision ismade to use a OMNI-AMP Amplifierwith a digital readout meter, themaximum sensitivity that can beachieved with a meter and OMNI-AMP Amplifier combination is 100microvolts.Please read the operating instructions which are on the side of the OMNI-AMP I Amplifier and on the bottom of OMNI-AMP II Amplifier before using the instrument.It is the policy of OMEGA Engineering, Inc. to comply with all worldwide safety and EMC/EMI regulations that apply.

欧米伽热电偶欧米伽热电偶是一种广泛应用于测量温度的仪器。
它非常精确，由于它的设计，它能够记录和传达精确的温度数据，使用者可以根据温度变化更加准确地把握时间节点。
它的历史可以追溯到1896年，当时由美国研究家爱德华古德曼发明。
古德曼受到朋友格莱夫先生的邀请，来他的实验室参与一个细菌实验，以探索细菌如何影响屠宰牛肉转变成牛肉腌渍多久。
他发现，温度升高会加速细菌的生长，所以他用一支可以测量温度的计量来测量这种变化。
为此，他将一支金属的温度计放入一种可变的抵抗物质中，并创造了一种记录温度的装置：欧米伽热电偶。
欧米伽热电偶是一种采用热电效应测量温度的仪器，它的基本结构包括一个用于改变抵抗的变阻器组件，它的表面覆盖着电镀的铂金或白金，以及用于检测变阻器抵抗变化的电路系统。
当温度上升时，变阻器中的抵抗值会增加，从而影响电路系统的输出实现温度测量。
欧米伽热电偶的技术有很多优点，例如，它可以提供卓越的精度，线路结构简单，可以测量低温（低至-200摄氏度），它所耗费的空间很小，使得它能够应用于各种小型系统中，它的耐腐蚀性很强，可以抵抗湿气和酸碱度变化等。
此外，欧米伽热电偶还具有很好的抗干扰能力，具有抗电磁暂态干扰、过压抗扰、超声波抗干扰等功能，其准确率可达到±0.2摄氏度左右。
欧米伽热电偶的应用非常广泛，例如，它可以用于空调、暖气、制冷、热水系统、蒸汽火力发电厂等系统的自动控制，也可以应用于汽车、火电、石化、矿山、电子等领域，以及实验室测量温度等。
随着技术的发展，欧米伽热电偶发展空间也不断拓展，它也可以用于环境监测、机器人定位系统等领域，以显示温度变化，指导未来的发展。
在欧米伽热电偶的应用中，冰点测量是最重要的一个环节。
为此，我们在这里介绍一种改进型欧米伽热电偶，采用“跳开关”的技术，增加了一个新的接点，当物体的温度低于设定值时，会自动触发跳开关，给出相应的控制信号。
由于它更容易控制和更精确，因此它被广泛应用于空调、制冷、暖气、影院、餐厅、车厂等低温系统的自动控制中。
欧米伽热电偶

本文将对欧米伽热电偶进行深入的介绍。
欧米伽热电偶是一种电阻温度检测器，它由两根不同的导线电阻接头和一个热电偶电阻组成。
当面对温度改变时，热电偶中的两个电阻之间的电势差也会随着温度的变化而变化，从而得到准确的温度测量数据。
欧米伽热电偶的主要优势在于它的快速反应和准确性。
由于热电偶本身可以极快地对温度变化作出反应，因此它可以比其他测量仪器获得更准确的温度测量数据。
此外，欧米伽热电偶还具有较高的灵敏度，可以检测微小温度变化。
欧米伽热电偶的应用非常广泛，它可以用来测量家用电器和工业环境中的温度。
它也可以用于测量建筑物内外的温度，帮助确定建筑物的温度设定和热量负荷分析。
在化学实验中，欧米伽热电偶也能够检测出物体的温度，因此它也被用于确定化学反应的温度和度量物体的热量能力。
此外，欧米伽热电偶还有一些其他的应用，比如用于自动充气系统中对温度的检测，用于食品加工行业中对食品温度的检测，用于医疗行业中对人体温度的检测等。
因此，欧米伽热电偶是一种非常有用的仪器，它能够快速准确地测量温度，广泛应用于不同行业，为企业提供了更高的生产效率和更
