The PRTXD Series are 2-wire
transmitters that provide a 4 to
20 mA
signal representing
temperature. The units include a
41⁄2 digit display and the RTD sensor.
The NEMA 4X (IP66) housing
protects the electronics. Units are
available with spring-loaded probes
for use with thermowells.
Specifications
Sensor: 100 W RTD element, 0.00385

update rate
Out of Range Indication:
ALARM 1: On display above
200°C (392°F)
ALARM 2: On display below
-50°C (-58°F)
Loop Supply Voltage: Any DC
supply/loop resistance that maintains
8 to 32 Vdc at gauge terminals
(reverse polarity protected)
Loop Output Characteristics:
4 to 20 mA output (see chart for loop
voltage characteristics), minimum
8V required at gauge terminals at
all times for proper operation
Test Function: Front panel TEST button
when held, sets loop current and display
to test calibration level, independent
of temperature input to allow testing of
system operation
