Huatian Cw124 Digital Display Temperature Transmitter

1 Summary    CW1200 series digital display temperature transmitter is a product which integrates temperature measurement and display. The product is displayed by 4-bit LED digital tube. After linear compensation, signal amplification, signal processing, etc., it can output industrial standard 4-20mA signal, and can work stably for a long time. It is widely used in petroleum, chemical industry, metallurgy and other fields.2 Features    Anti-interference design    Reduce lightning damage    Zero shift function    Nonlinear correction function    4~20mA output  3 Main parameters    Supply voltage:(12~30)VDC,recommend 24VDC    Display mode: 4-digit LED digital tube    Output signal:(4~20)mA    Measuring range: (0~200)ºC(According to the needs)    Output accuracy:  Grade 0.25,Grade 0.54 Appearance and wiring 1. Fig 1 is for the reference outline of transmitter2. The external wiring of transmitter is shown in Fig 2.5 LED panel description5.1Panel descriptionThe parameters of the transmitter can be modified through the buttons on the panel. In normal measurement state, there is no function definition for position selection key and increase key.5.2 Function description5.3 After the temperature transmitter is delivered from the factory, the product has been debugged and calibrated, so the user can't  modify it at will, so as to avoid that the transmitter can't work normally.5.4 IllustrationThe panel shape and key function are shown in Fig 3.                      Fig 3The function of bit selection key is multiplexed and can be used as a reduction function. The other key functions are shown in Figure 3 above.6. Precautions6.1 Ensure the fluidity of the measured medium.6.2 In order to ensure the accuracy, large range and small range transmitters can not be used in place of each other. Otherwise, it will cause over-voltage damage or inaccurate measurement.6.3 After opening the front and back cover of the transmitter, it is necessary to tighten the front and back cover to prevent moisture from entering the housing and causing damage to the transmitter.6.4 When the transmitter is installed, it should be vertical to the mounting frame, and the measuring point and installation position should be at the same level6.5 The transmitter shall not be installed in the environment with strong mechanical vibration. It is necessary to close the valve of gas (liquid) pipeline before installation.6.6 The transmitter shall be installed in the place with lightning protection device, and ensure good grounding to prevent damage to the transmitter.7. After sales serviceThe warranty period of this product is one year under the condition that the user completely complies with the instructions, the use method and no one is damaged./* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
