Pc Connection Rs232 - thyracont VD9 Betriebsanleitung

Analog Recorder Output:
Transducer Type 1 (see chapter 5.3)
linear, 1 - 1400 mbar corresponds to 0 - 10 V
Other Transducer Types
logarithmic according to the following formula (up to max. 1000mbar):
Vout = (10V / Decades) x ( log(p[mbar]) - exp0 );
Decades: Number of decades that are covered by the measuring range;
p: Actual pressure in mbar;
exp0: Exponent off the lower measuring range limit in mbar.
Example:
Transducer Type 2, 1400-0.001mbar
(see chapter 5.3)
Actual pressure:
Decades:
exp0:
Vout = (10V / 6) x ( log(0.5) - (-3) ) = 4.50 V ;
Steady Control Output:
