(1) Process temperatures above 185 °F (85 °C) require derating the ambient limits by a 1.5:1 ratio.
(2) 220 °F (104 °C) limit in vacuum service; 130 °F (54 °C) for pressures below 0.5 psia.
(3) -20 °F (-29 °C) is the lower process temperature limit with option code P0.
(4) 160 °F (71 °C) limit in vacuum service.
(5) Not available for 2051_CA.
(6) Upper limit of 600 °F (315 °C) is available with 1199 seal assemblies mounted away from the transmitter
with the use of capillaries and up to 500 °F (260 °C) with direct mount extension.
Humidity Limits
0–100% relative humidity
Volumetric Displacement
Less than 0.005 in
Damping
The Damping command introduces a delay in processing which increases the response time of
the transmitter; smoothing variations in output readings caused by rapid input changes. In the
2051 Wireless pressure transmitter, damping only takes effect when the device is placed in high
power refresh mode and during calibration. In normal power mode, the effective damping is 0.
Note that when the device is in high power refresh mode, battery power will be depleted rapidly.
