DJ-DJ1300 Pressure Transmitter Installation Tutorial，Easy Even for Beginners！

As a high-quality product among diffused silicon liquid and gas pressure sensors，the DJ-DJ1300 pressure transmitter features a simple and easy-to-follow installation process。This tutorial will provide a detailed introduction to the installation steps for the DJ-DJ1300 pressure transmitter，so even beginners can handle it with ease。Whether you need to understand the principle of diffused silicon pressure sensors or are looking for genuine original products，this article can provide practical guidance。

一、Preparation Before Installation

Before starting the installation of the DJ-DJ1300 pressure transmitter，the following preparations should be completed：

1.Check Product Integrity：Ensure that the received DJ-DJ1300 pressure transmitter is well packaged，undamaged，and complete with all accessories。The core components of the diffused silicon liquid and gas pressure sensor should be free of scratches or deformation。

2.Prepare Tools：Basic tools such as a wrench，screwdriver，and sealing tape may be required during installation。If a special interface is used，the corresponding adapter should also be prepared。

3.Environmental Check：The installation environment should avoid strong electromagnetic interference，with a recommended temperature range between -20℃~60℃ and humidity not exceeding 85%RH。The performance of diffused silicon sensors is greatly affected by the environment，so special attention is required。

4.Read the Manual：Although the installation of the DJ-DJ1300 is relatively simple，different models of diffused silicon pressure transmitters may have slight differences，so it is recommended to browse the product manual first。

二、Installation Steps for the DJ-DJ1300 Pressure Transmitter

1.Process Connection：The DJ-DJ1300 typically uses a G1/2" or NPT1/2" threaded connection。During installation，please note：
- Wrap sealing tape around the thread to ensure sealing performance。
- Pre-tighten by hand first，then tighten 1-1.5 turns with a wrench，avoiding excessive force that may damage the sensor。

2.Electrical Connection：
- Power cable：The DJ-DJ1300 is typically powered by 24VDC，with the red wire connected to the positive terminal and the black wire connected to the negative terminal。
- Signal cable：The 4-20mA output wire should be connected to a PLC or display instrument，with attention to polarity。
- Shielded cable is recommended，and proper grounding should be ensured。

3.Orientation Adjustment：The installation orientation of a diffused silicon pressure transmitter affects measurement accuracy。The optimal installation position for the DJ-DJ1300 is with the pressure port facing downward，to prevent impurities in the medium from depositing on the sensor diaphragm。

4.System Venting：For liquid pressure measurement，the system must be vented after installation。Open the valve slowly，allow the medium to fill the pipeline，and discharge the air。

三、Commissioning and Calibration

1.Zero Calibration：Under no-pressure conditions，perform zero calibration using the zero adjustment screw on the transmitter or via HART communication。

2.Range Check：Apply full-scale pressure and check whether the output signal is 20mA（or the corresponding voltage value）。If there is any deviation，range calibration is required。

3.Linearity Test：It is recommended to test at 25%，50%，and 75% range points to ensure that the output linearity of the DJ-DJ1300 meets the requirements。

4.Temperature Compensation：If the operating ambient temperature varies significantly，check whether the temperature compensation function is working properly。

四、Common Problems and Solutions

1.No Signal Output：
- Check whether the power wiring is correct
- Confirm whether the fuse is intact
- Measure whether the supply voltage is normal

2.Large Measurement Deviation：
- Check whether zero drift has occurred
- Confirm whether the medium has corroded the sensor diaphragm
- Check whether the pipeline is blocked

3.Signal Fluctuation：
- Check whether the grounding is good
- Confirm whether there are strong electromagnetic interference sources nearby
- Check whether the medium flow is stable

For applications requiring high-precision displacement measurement，such as injection molding machines and other industrial equipment，we recommend using the domestic KTM displacement sensor injection molding machine tie-bar electronic ruler resistance ruler tie-rod linear displacement sensor，which adopts conductive plastic film technology，with accuracy up to 0.04%FS and an IP67 protection rating，making it especially suitable for harsh industrial environments。

五、Maintenance and Care

1.Regular Inspection：It is recommended to check the sealing performance and electrical connections of the DJ-DJ1300 pressure transmitter once every 3 months。

2.Cleaning and Care：
- Clean the sensor housing with a soft cloth
- Avoid using corrosive cleaning agents
- Check whether there is medium crystallization at the pressure port

3.Spare Parts Management：It is recommended to keep vulnerable parts such as O-rings and sealing gaskets in stock for unexpected needs。

4.Record Keeping：Establish a maintenance file to record the data of each calibration and repair，making it easier to track changes in sensor performance。

Summary

Although the installation process of the DJ-DJ1300 diffused silicon liquid and gas pressure transmitter is simple，attention to detail is still required。Correct installation and regular maintenance can significantly extend the service life of the sensor and ensure measurement accuracy。For other pressure transmitter models such as DG1300-PJ-1-2-10/AAZN and LABO-RT-INS，the installation methods are also largely similar。
