| KGJ23-1: |
Low concentration: 2001000 Hz,
linear to 04.00%CH;
High concentration: 12002000 Hz, linear to 040.0%CH;
When load resistance >1.5 k,
high level output >3 V, low level output <0.5 V. When
using the transmission cable with C0.06 ¦ÌF/km,
L0.8mH/km,
R19 ¦¸/km,
the transmission distance shall be 2 km; The red LED H10 is for indicating frequency output |

and this model has no function of power off output,
and the on/off output displays the measuring range of
high and low concentration methane:
When the on/off output is low level signal, then 15 mA is linear to 0 4.00%CH;
When the on/off output is high level signal, then1 5 mA is linear to 0 40.0%CH |
