Temperature Limits
Ambient
• –40 to 185 °F (–40 to 85 °C).
Storage
• –60 to 250 °F (–50 to 120 °C).
Transient Protection Option (available at a later date)
The transient protector helps to prevent damage to the transmitter from
transients induced on the loop wiring by lightning, welding, heavy electrical
equipment, or switch gears. The transient protection electronics are contained
in an add-on assembly that attaches to the standard transmitter terminal
block. The transient protector is tested per the following standard:
ANSI/IEEE C62.41-1991 (IEEE 587), Location Categories A2, B3.
1kV peak (10
1000
S Wave)
6kV / 3kA peak (1.2

S Combination Wave)
6kV / 0.5kA peak (100 kHz Ring Wave)
4kV peak EFT (5
50 nS Electrical Fast Transient)
Nominal clamping voltages:
• 77 V (normal mode)
• 90 V (common mode)
Alarms
The AI block allows the user to configure the alarm to HI-HI, HI, LO, or LO-LO,
with a variety of priority levels and hysteresis
Status
If self-diagnostics detect a sensor burnout or a transmitter failure, the status of
the measurement will be updated accordingly.
Humidity Limits
0–100% relative humidity.
Turn-on Time
Performance within specifications is achieved less than 10.0 seconds after
power is applied to the transmitter.
(1) Sigma (
) is the Standard Deviation of a statistical distribution, and describes the dispersion (spread) of the distribution.
