10-11
Output
Two wire 4–20 mA, user-selectable for DP, AP, PT, or mass flow. Digital
HART protocol super imposed on 4–20 mA signal, available to any host
that conforms to the HART protocol.
Power Supply
External power supply (or PS120 /PS240 option) required. Operates on
11–55 V DC with no load.
Load Limitations
Loop resistance is determined by the voltage
level of the external power supply, as described
in the following diagram:
Temperature
Integral Mount
Process: –40°F to 450°F (–40°C to 232°C).
Ambient: –40°F to 185°F (–40°C to 85°C).
Storage: –50°F to 212°F (–40°C to 100°C).
Contact factory for higher temperatures.
Damping
Response to step input change can be user selectable from
0 to 30 seconds for one time constant. This in addition to sensor
response time of 0.2 seconds.
Turn-on-Time
Performance within specification less than two seconds after power
is applied.
Humidity Limits
0–100% relative humidity.
