WebmilliVolt transmitters convert -50 to 375mV DC sensor input signals to 4-20mA or 0-10V DC outputs for interfacing to controllers or other instrumentation. ... The ST132 is a low-cost two-wire transmitter that converts a millivolt or thermocouple sensor input to a proportional 4-20mA control signal. Power is received from the output loop current. WebIn this unit converter the following formulas are used to convert the sensitivity in dB into the transfer factor and vice versa: S dB re 1V/Pa = 20 log 10 (TFmV/Pa/1000 mV/Pa) or. TF mV/Pa = 1000 mV/Pa × 10(S dB re 1V/Pa/20). Here: S dB re 1V/Pa is the sensitivity in dB relative 1 V/Pa, TF mV/Pa is the transfer factor in mV/Pa and
