PRTXD Series
溫度變送器，帶顯示屏和RTD傳感器
Two-Wire Transmitter
4 to 20 mA Output
3 1/2 Digit Display
RTD Probe Included, Available with 4" or 12" Immersion Lengths, Fixed Length or Spring Loaded for Thermomell Use
NEMA 4X (IP66) Housing
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.
