The common sense of human-machine interface is the first knowledge for beginners. The product consists of hardware and software. The hardware part includes processor, display unit, input unit, communication interface, data storage unit, etc. HMI software is generally divided into two parts. It is two parts, namely the system software running in the HMI hardware […]

First, overcurrent (OC) Overcurrent is the most frequent phenomenon of inverter alarms. 1.1 Phenomenon (1) When restarting, it will trip at a speed. This is a very serious overcurrent phenomenon. The main reasons are: load short circuit, mechanical parts are stuck; inverter module is damaged; motor torque is too small and so on. (2) Jumping […]

•Sensitivity: The thermistor can change with very small temperature changes. Accuracy: Thermistors provide high absolute accuracy and error. Cost: For the high performance of the thermistor, its cost performance is very high. • Robustness: The construction of the thermistor makes it extremely rugged. • Flexibility: Thermistors can be configured in a variety of physical forms, […]

What is a terminating resistor? The resistance of the pair of communication lines is connected in parallel at both ends of the online network (on the two communication ports that are farthest apart). The termination matching resistance value depends on the impedance characteristics of the cable, regardless of the length of the cable. RS-485/RS-422 is […]

When choosing the right model of the camera, complex parameter comparisons such as image resolution, camera sensitivity and temperature range are often required. In short, the temperature range indicates the lowest temperature and highest temperature that a thermal imager can measure. What you should know about the wide temperature range of thermal imaging cameras 1. […]
