Table 1. Specifications
Input Signal Source
Hall Effect Sensor and magnet array
Transmitter Output Signal
Analog: 4 to 20 mA DC
High saturation: 20.5 mA
Low saturation: 3.8 mA
High alarm(1):> 21.0 mA
Low Alarm(1):< 3.6 mA
Digital - PENDING:
HART 1200 Baud Frequency Shift Keyed (FSK)
HART Version 7
HART impedance requirements must be met to
enable communication. Total shunt impedance
across the master device connections (excluding the
master and transmitter impedance) must be between
230 and 600 ohms.
HART receive impedance:
Rx: 28.06k ohms
Cx: 5.84 nF
Output Current Limit: 30 mA DC maximum
Integral Limit Switch - PENDING
Two isolated solid state limit switches, configurable
throughout the calibrated travel range or actuated
from a device alert
Off State: 0 mA (nominal)
On State: up to 1 A
Supply Voltage: 24 - 30 VDC
Travel Limit Trip Points
Two
Recommended Power Supply
24 to 30 volts DC; 25 mA
Instrument has reverse polarity protection.
A minimum compliance voltage of 17.75 VDC (due to
HART impedance requirement) is required to
guarantee HART communication
Reference Accuracy
$1% of output span. Includes combined effects of
hysteresis, linearity, and deadband
Limit Switch: 2% of travel span
Repeatability
$0.25% of span
