Jingkong JK Pressure Sensor
I. Model Selection and Installation
-
Q1: How to quickly select the correct model of JK electronic pressure switch?
A1: Focus on three key points: ① Match the actual pressure range; ② Confirm the power supply (standard DC12~24V) and output type (NPN/PNP, etc.); ③ Select the protection level according to the operating environment (IP65 or above for dusty or humid environments).
-
Q2: What are the key safety precautions before installation?
A2: Be sure to cut off air pressure and power supply before installation. Non-professionals are strictly prohibited from operating. Standard models cannot be installed in flammable or explosive environments.
-
Q3: What are the simple specifications for piping and wiring?
A3: Clean impurities before piping to ensure sealing without leakage. Wire strictly in accordance with the manual, avoid running in parallel with high-voltage electricity, and ensure firm plug connection.
II. Setting and Operation
-
Q1: How to quickly set the basic pressure?
A1: Press the setting key in measurement mode. The screen will alternately display the output type and set value. Adjust with the up and down keys and confirm.
-
Q2: What to do if the measured value fluctuates greatly?
A2: Enable the digital filter function or appropriately extend the response time. At the same time, check if the piping is leaking and if the medium is clean.
-
Q3: How to switch the pressure unit?
A3: Enter the general measurement mode item, select the desired unit (such as MPa, kPa) with the up and down keys, and confirm.
III. Troubleshooting
-
Q1: How to handle if the display screen has no display?
A1: First, check if the power supply is normal and if the wiring is loose. If there is still no display when the power supply is normal, contact after-sales service for repair. Do not disassemble it by yourself.
-
Q2: What to troubleshoot if there is no output signal?
A2: Check if the set value is reasonable and if the wiring is correct. Confirm that the medium pressure is within the set range. You can enter the output confirmation mode to test the function.
-
Q3: How to calibrate if the measured value has a large deviation?
A3: Calibrate with the display value fine-tuning function. If the deviation is still large after fine-tuning, check if the sensor diaphragm is contaminated or if the piping is leaking. If ineffective, contact the official for calibration.
IV. Maintenance and Others
-
Q1: What is the warranty period?
A1: Consumables are guaranteed for 1 year. Artificial damage is not covered by the warranty.
-
Q2: What should be noted for daily maintenance?
A2: Regularly clean the surface with a dry and soft cloth, and check if the installation and wiring are firm. Knocking or disassembling the equipment is strictly prohibited.
