Frequently Asked Questions - TRS-400 Steren
How do I calibrate the TRS-400 sensor?
The TRS-400 is factory-calibrated. If you need manual calibration, place the sensor in a known temperature reference (e.g., ice water at 0°C) and adjust the offset via your controller if supported.
What is the operating voltage of this sensor?
The TRS-400 operates on 12V DC. Ensure your power supply is regulated and does not exceed 15V to avoid damage.
Can I use the sensor outdoors?
Yes, the TRS-400 features an IP65 protection rating, making it resistant to dust and water jets, suitable for outdoor installation.
How do I connect the sensor to a controller?
Connect the output signal (0-5V analog) to an analog input on your controller. Power the sensor with 12V DC and ground accordingly. Refer to your controller's manual for specific wiring.
What is the response time of the sensor?
The typical response time is under 2 seconds for a step change in temperature. This ensures reliable and quick monitoring.
How should I clean the sensor?
Use a soft, dry cloth to wipe the sensor body. Do not use water, solvents, or abrasive cleaners as they may damage the protective casing.
Is the sensor waterproof?
The IP65 rating means it is water-resistant against splashes and jets, but it is not suitable for submersion. Avoid fully immersing the sensor in water.
What is the measuring range of the TRS-400?
The sensor measures temperatures from -20°C to 80°C with an accuracy of ±0.5°C, covering most environmental monitoring needs.
Does the sensor require a battery?
No, the TRS-400 is powered by an external 12V DC supply. It does not use batteries, ensuring continuous operation without replacements.
What should I do if the sensor shows no reading?
First, check the power supply and wiring connections. Ensure the output pin is correctly connected to the controller. If the problem persists, test the sensor with a known good reference; if it still fails, the sensor may be faulty and should be replaced.
