VDT02-W is a powerfull cost effective dual channel instrument for relative shaft vibration measurement. Viditech's "everything inside" technology alows machinery analysis in field as well as standard L1 and L2 protection. You do not need PC for setup - easy to use intuitive user inteface with 2 line alphanumeric LCD display does not require any training. Implementaction of ModBus RTU industry standard ensures possible remote online monitoring and setup.
Digital signal processing ensures maximal performace - FFT frequency step as small as 1.8Hz within full frequency range. You can download and visualize trends, postmort and measure orbits using our free Control Center software (basic version). Check out full specification and feel free to contact us for more details.
