Product Specs

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 electronics.

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.

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 (See Drawing): 0.9 m (3') long, 2-conductor 22 AWG cable
Material and Color: NEMA 4X (IP66) ABS/Polycarbonate housing, light gray gasketed rear cover connection and
probe material: 1.2 NPT male hex nipple, 316 stainless steel probe sheath
Operating Temperature (Electronics): -20 to 85°C (-4 to 185°F)
Storage Temperature: -40 to 95°C (-40 to 203°F)
    Transmitter: Approx 340 g (12 oz)
    Shipping Weight: Approx 450 g (1 lb)
Range: -50 to 200°C (-58 to 392°F)
Resolution: 0.1 degree
Accuracy: ±0.1% of span plus max sensor error of ±0.3°C at 0°C or ±1.1°C at 150°C

Can the 4-20 mA output be scaled on this transmitter. ie could you scale your 4-20 for 0 - 50 degrees?

Asked by: Mack
Hi Mack, Thank you for the inquiry. Yes, the scale can be modified to 0 to 50 degrees. Manual describes the configuration steps. Best regards OMEGA
