美国omega PRTXD-4温度变送器
温度变送器，带显示屏和RTD传感器 PRTXD Series 温度变送器，带显示屏和RTD传感器 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. 规格： 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) Weight: 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 注释: Comes with complete operator’s manual.
