1. Can sensors be directly connected to a computer by converting 485 or 422 interfaces to USB?
Answer: No, we use TTL serial port and need to use TTL serial port cable conversion.
2. Is there too much difference between powering on two units at the same time, one at 390 and the other at 650?
Answer: For the first use, place the sensor in a ventilated and clean environment, and continuously power on for 24 hours to perform zero point automatic calibration.
3. Why do infrared sensors need to be preheated, and can they not be preheated?
Answer: No, preheating is a process of stabilizing the light source and detector inside the infrared sensor. If it is not preheated, the test data will have deviations. If you have more questions, please consult our online customer service.
