What are the effects of changes in temperature and humidity on the human body_Temperature and humidity sensors can quickly sense ambient temperature and humidity

Temperature is a physical quantity that measures the heat and cold of an object. In people’s production and scientific research projects, many are carried out at specific temperatures, which is closely related to people’s lives; humidity refers to the relative humidity of the air, generally used as %RH express. Temperature and humidity are closely related.…

What are SOE signals and COS signals?

SOE signal: sequence of events (resolution not greater than 2ms), record the time of occurrence of events ( switch or protection action) one by one in order, this is the sequence of events record. COS signal (non-SOE): remote signal displacement (without time stamp). The SOE signal is sent with a time stamp at the station…

How to choose a suitable frequency converter?

(1) Understand the variable frequency load type . The correct selection of the inverter is very critical for the normal operation of the control system. When selecting an inverter, you must fully understand the characteristics of the load driven by the inverter. In practice, people often divide production machinery into three types: constant torque load,…
