Ambient temperature
effect on zero and span These values are for transmitters with zero based spans, silicone oil fill, and Has-
telloy C-276 isolating diaphragms. The effects listed are for a variation of ±25°C
(±45°F) from a calibration done at a temperature between -30° and +80°C (-22°
and +176°F), as long as the variation does not take the transmitter out of the tem-
perature specifications listed under
Temperature limits.
Range C with
extension ±(0.50% URL + 0.20% span)
All others ±(0.25% URL + 0.15% span)
Humidity limits 5% to 100% noncondensing continuous when the covers are properly installed and
the conduit is sealed
Pressure limits The minimum static pressure for all types is 3.4 kPa absolute (14.0 in. H
2
O abso-
lute or 0.5 psia). The maximum pressure is limited by the pressure rating of the
flange mounted on the high pressure side of the transmitter (Table
1-2 , nomencla-
ture position 8).

≤
0.1% of URL for 1 g from 1 to 2,000 Hz in any axis of the transmitter

Damping/response
time (one time constant
— approximately 62%
of final reading) Analog and digital response to a step input change is adjustable from 0.0 to
32.0 secs and is entered during configuration. This value is in addition to:
Cell response time: dependent on cell and fill fluid
Electronics response time: approximately 0.25 secs
RFI/EMI effects ±0.1% of URL in fields from 4 to 1,000 MHz at 10 V/m
Surge tolerance Complies with IEEE 472 test criteria. 2.5 kV, 1.5 MHz, 150-
