LVDT Smart Indicator



The Model 4215-L Smart Indicator is an intelligent microprocessor-based instrument designed for the measurement and control of dual channel LVDT (Linear Variable Differential Transformer) measurement fixtures. It combines two LVDT channels, print capabilities and RS 232/485 serial communication into a versatile platform that can be customized to deliver the most powerful and affordable instrumentation in its class.


The ESL Model 4215-L Advanced Digital LVDT Meter provides all excitation and signal conditioning necessary to operate dual LVDT expansion measurement fixtures. The average extension is computed automatically and displayed. The ESL Advanced Digital LVDT Meter also features analog outputs, limit switching, individual unit conversion and a two-line display. Factory options support mixing and matching of strain gauge and LVDT sensor inputs.
