Product Introduction:
Compared with traditional XC series dynamic coil instruments and ordinary T series analog instruments, XM series digital instruments have unique advantages such as high accuracy, strong seismic resistance, good reliability, easy installation, clear readings, no parallax, and remote observation. There are various adjustment forms including two position, three position, time proportional, thyristor continuous adjustment, P, I, D, etc. It can also add over limit sound alarm function and alarm contact output function as needed. It is an updated product of XC series instruments and can be widely used in metallurgy, textile, plastic machine, incubator, oven, refrigeration, chemical and medical industries for temperature measurement and automatic control in the range of -200~1800 ℃. Equipped with corresponding sensors, it can also be used for displaying and controlling parameters such as pressure, flow rate, and liquid level.
