LTR51 Measurement Module for Accurate Frequency Signal Measurement

The LTR51 measuring modules include H-51 measuring transducers designed for frequency measurements of sinusoidal or periodic pulse signals. They are part of LTR measuring units. LTR51 is a module with configurable number of measuring channels, which can be used for multi-channel measurement of frequency, period, number of pulses both on pulse outputs of various devices and sensors (counters, flow meters, shaft speed sensors) and on analogue outputs. LTR51 is designed as a carrier for installation of 8 two-channel measuring submodules H-51FH or H-51FL, and the number of input channels is determined by the number of installed submodules. Each parallel measurement channel has a separately configurable dual-threshold input signal selection circuitry.
