The industrial switch-type electronic temperature sensor with display function is a highly integrated intelligent monitoring and control device. It integrates high-precision temperature sensing, real-time digital display and programmable switch output into a robust and compact housing. Specifically designed for harsh industrial environments, this device not only continuously and accurately measures the temperature of the medium and directly displays the value on a clear local screen, but also automatically triggers relay or solid-state switch signals when the temperature reaches the critical point preset by the user. This signal can be directly used to drive alarms, start or stop cooling fans, heaters or other actuators, thereby achieving automatic temperature monitoring and active management. It is a key component for ensuring equipment safety, optimizing process flows and preventing overheating failures.
The core of the sensor adopts industrial-grade temperature sensing elements such as thermocouples (like K-type, J-type) or platinum resistors (like PT100, PT1000), ensuring high accuracy and stability within a wide temperature range. The temperature sensing probe directly contacts the medium to be measured (such as oil, water, air, or metal surfaces), converting temperature changes into linear electrical signals.
Signal processing and display: The built-in microprocessor amplifies, linearizes and digitizes the electrical signal, and ultimately drives the high-brightness LED or LCD display to provide intuitive real-time temperature readings.
Intelligent switch control: Users can set one or two independent temperature set points (such as alarm points or shutdown points) via the buttons on the device or through communication interfaces (if applicable). When the measured temperature reaches or exceeds the set point, the integrated relay (mechanical type) or solid-state switch (electronic type) inside will immediately change its state (normally open contacts close or normally closed contacts open), outputting a passive dry contact signal or level signal. This switch signal can be directly connected to a PLC, control cabinet, or drive external equipment, forming a complete monitoring-feedback-control closed loop.
Combining "sensing + display + control" into one, it eliminates the complex wiring, installation and calibration work of external display instruments and independent temperature switches, significantly simplifying the system architecture and saving space and cost.
Local display enables on-site inspection and maintenance personnel to quickly read the temperature without the need for additional tools, greatly enhancing operational convenience.
Rugged housing: Typically made of stainless steel or high-strength engineering plastics, providing excellent mechanical protection and corrosion resistance.
High protection level: It features an IP65/IP67 or higher protection level, effectively resisting dust, water splashes, oil stains and rinsing, making it suitable for harsh working conditions that are damp and dusty.
Vibration resistance and wide temperature operation: The design can withstand mechanical vibration and operate stably within a wide range of ambient temperatures.
Utilizing highly stable temperature sensing elements and advanced signal processing technology to ensure accurate measurement and rapid response throughout the entire range.
Users can easily set the switch points, hysteresis (to prevent frequent switching actions), and temperature display units (℃/℉) via the device's built-in buttons or through the communication interface (for supported models).
Switch Output: Offers single-pole double-throw (SPDT) relays or solid-state outputs, with contact ratings capable of driving common AC/DC loads.
Optional additional output: Some models also offer analog output (such as 4-20mA or 0-10V) for transmitting temperature signals to the central control system over long distances.
Flexible installation: Offers various probe forms (such as straight rods, bent rods, and threaded mounting seats) and process connection methods (such as G1/2" thread and flange), to meet the installation requirements in different locations like pipelines, oil tanks, and bearing housings.
This sensor is widely used in industrial fields where temperature monitoring and interlock control are required:
• Hydraulic and lubrication systems: Monitor the oil temperature in hydraulic oil tanks, return oil lines, and gearboxes. When the temperature exceeds the limit, start the cooler or trigger an alarm.
Power transmission equipment: Monitor the temperature of motors, compressors, pumps and bearings to achieve overheat protection.
• Process industry: Temperature monitoring and control of liquid or gaseous media in pipelines, reactors, and storage tanks.
• HVAC (Heating, Ventilation, and Air Conditioning): Monitor the temperature of cooling water and chilled water, and control the operation of water pumps and cooling tower fans.
Plastic machinery: Monitoring mold temperature or extruder barrel temperature.
Power generation and energy: Monitor generator windings, transformer oil temperature or gas turbine intake temperature.
1. Location selection: Install the probe at a position that can represent the average temperature of the measured medium and where the fluid flows fully, avoiding dead zones or areas close to heat or cold sources.
2. Correct installation: Ensure the probe has good contact with the measured medium. For pipe installation, the insertion depth of the probe should be sufficient. Use appropriate sealing materials (such as gaskets, PTFE tape) to ensure there is no leakage at the process connection.
3. Electrical connection: Connect the power supply, display backlight (if needed), switch output lines, and analog output lines strictly in accordance with the wiring diagram. Pay attention to the polarity of the power supply and provide appropriate protection (such as fuses) for the relay load.
1. After being powered on, the display screen will show the current temperature.
2. Enter the setting mode (usually by long-pressing a certain function key), and set the required switch point temperature values, hysteresis values, display parameters, etc. in sequence.
3. Exit the setting mode, and the device will operate according to the new parameters. Simple function verification can be conducted using a known temperature source (such as a constant temperature bath).
Regularly clean the display screen and sensor housing, and check the installation tightness and cable integrity. When the system is shut down, cross-verify the sensor readings with a calibrated portable thermometer.
Common Faults and Troubleshooting:
If the display shows abnormal or erratic readings, check whether the wiring is loose, the probe is damaged or improperly installed, and if there is strong electromagnetic interference nearby.
If the switch does not operate: Check whether the set point is correct, measure whether the actual temperature has reached the set point, and test whether the load circuit at the output end of the switch is normal.
Calibration: For applications with extremely high precision requirements, it is recommended to send the sensor to a qualified laboratory for calibration on a regular basis (such as annually).
This product offers users a one-stop solution for temperature monitoring and control through highly integrated design. It simplifies engineering design, reduces procurement and installation costs, enhances system reliability, and creates significant value for users through preventive maintenance (avoiding unexpected shutdowns and equipment damage due to overheating) and process optimization (keeping process temperatures within the optimal range). Its robust design ensures long-term stable operation in critical industrial applications, making it an ideal choice for improving the level of equipment automation and safety.
