SIGNAL TRANSDUCER

LINEARIZER
LTP1 -■ UseConverts measurand into linear signal. Such as a

LTP1-A6F5

differential pressure signal, a signal of weir-type flow

(80×50×121mm/350g)

meter or analyzer, or a signal unrelated to linearity.

■ Connection diagram■ Features
1. A digital linearizer that uses ADC, ROM and DAC.
2. Constant voltage/current output.
3. Withstand voltage between electric circuit and outercase is AC2, 000V (50/60Hz) for 1 minute, or between
input and output is AC1, 500V (50/60Hz) for 1 minute.
4. Impulse withstands voltage 5kV, 1.2/50µs (between
electric circuit and outer case), and positive/negative
polarity 3 times each is guaranteed.

Indicated in ( ) are the polarities in the case of DC auxiliary supply.
