(4~20)mA isolated transmission output: strong anti-interference ability, ensure the accuracy of data transmission.
RS485 communication (MODBUS-RTU protocol): supports remote monitoring and data communication, facilitating system integration and remote management.
Manual and automatic temperature compensation: choose the compensation method according to the actual demand to ensure the accuracy of the measurement results.
High and low alarm (relay output): automatically triggers an alarm when the measured value is out of the set range, ensuring production safety.
Buzzer/LCD backlight switch: Convenient for users to operate and monitor in different environments.
Instrument panel installation: Make sure to read the installation section carefully according to the instructions.
Indoor installation: Avoid wind, rain and direct sunlight to ensure normal operation of the instrument.
Well-ventilated: Prevent the internal temperature of the instrument from rising and affecting the performance.
Horizontal installation: avoid tilting as much as possible to ensure the accuracy of measurement.
Avoid the workplace where the ambient temperature exceeds 60℃.
Avoid workplaces where the humidity of the working environment exceeds 85%.
Keep away from electromagnetic interference sources.
Avoid places with strong mechanical vibration.
Avoid places where the temperature changes greatly and condensation is easy to form.
Avoid places with a lot of fumes, steam, moisture, dust and corrosive gases.
Open a 92.5*92.5mm mounting hole in the instrument cabinet or mounting panel, and the thickness of the mounting panel should be between 1.5mm~13mm.
