VB-Z450 thermal expansion monitor is a set of high reliability monitoring and protection instrument, with differential transformer type linear displacement sensor (LVDT), used to monitor the steam turbine or other rotating machinery of all kinds of valve stroke. Can be used to measure steam turbine cylinder thermal expansion. When the measured value exceeds the limit, it can provide alarm relay switching contact output to ensure the safety and reliability of the machine Run. Internal integrated photoelectric isolation of 4 ~ 20mA current output, especially suitable for serious interference industrial field use, convenient connection with DCS, PLC system. The product has the characteristics of high precision, stable performance, strong anti-interference ability, high reliability, easy installation and so on. It can be widely used in electric power, machinery, chemical industry, metallurgy and other enterprises.
