–
10.00 VDC
Response Time
F.S Ranges ≥ 1 Torr, from 0
% to 90% of F.S response
time is 40ms. For 0.1Torr F.S from 0% to 90%
response time is 80ms.
Sampling Rate For transmitters with ranges > 1 Torr (1.33 mbar), the
analog output signal is updated approximately
1000/sec
. For transmitters with ranges ≤ 1 Torr (1.33
mbar), the analog output signal is updated
approximately 500 times/second

(1) Accuracy specification includes non-linearity, hysteresis, and non-repeatability.
(2) Resolution specification is best obtainable under ideal laboratory conditions. Actual resolution in service may vary.
(3)
The transmitter’s electronics are not sealed against entry of dust, rain, or snow, and therefore can be damaged by use outdoo rs
