The PRTXD Series are two-wire
transmitters that provide a 4 to 20 mA
signal representing temperature.
The units include a 3 1/2 digit display
and the RTD sensor. The NEMA 4X
(IP66) housing protects the
Units are available with
4 inch or 12 inch fixed length or
spring loaded RTD probes. Spring loaded
RTD probes provide good thermal contact
when used in thermowells.
SPECIFICATIONS Sensor: 100 W RTD element, 0.00385 alpha coefficient IEC-751 class B: ±0.3°C at 0°C, ±1.1°C at 150°C Display: 41.2 digit LCD, 1.2" digit height, 4 readings per second, nominal display 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 8 V 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 Wiring Connections
