Ranges
Output
Code S: 420 mA dc
Code N: 1-5 volt dc, low power
(Outputs are directly proportional to the input pressure)
Rangedown
20 to 1
Load Limitations
Reverse polarity protection is standard. Maximum loop resistance is determined by the power supply voltage as described by the following equations:
Max. Loop Resistance = 43.5 (Power Supply Voltage 10.5)
Power Supply
External power supply required. Transmitter operates on
10.536 V dc with no load (612V for Low Power). Reverse
polarity protection is standard.
Current Draw
Output Code N: ≤ 3 mA without LCD display.
Overpressure Limits
Range 1: 120 psig max
All other ranges: two times the URL
Burst Pressure
11,000 psi for all ranges
Zero can be suppressed between atmosphere for gage
transmitters or 0 psia for absolute transmitters and upper range
limit, provided the calibrated span is equal to or greater than the
minimum span, and the upper range value does not exceed the
upper range limit.
Time Response
Time Constant: 200 milliseconds
Dead time: < 0.1 s
Update rate: 20 times per second minimum
Temperature Limits
Process
Silicone fill sensor: 40 to 250 °F (40 to 121 °C)
Inert fill sensor: 22 to 250 °F (30 to 121 °C)
Process temperatures above 185 °F (85 °C) require derating
the ambient limits by a 1.5:1 ratio:
Ambient:
Storage:
50 to 230 °F (46 to 110 °C)
40 to 185 °F (40 to 85 °C) with LCD display
Humidity Limits
0100% relative humidity
Volumetric Displacement
Less than 0.00042 cm3
Turn-on Time
2.0 seconds, no warm-up required
Transmitter Security
Activating the transmitter security function prevents changes to the
transmitter configuration, including local zero and span
adjustments. Security is activated by an internal switch.
Failure Mode
If self-diagnostics detect a sensor or microprocessor failure, the
analog signal is driven either high or low to alert the user. High or
low failure mode is user-selectable with a jumper on the
transmitter. The values to which the transmitter drives its output in
failure mode depend on whether it is factory-configured to
standard or NAMUR-compliant operation. The values for each are
as follows:
