4-20mA temperature transmitter
Description
UTB9 integrated 4-20mA temperature transmitter thermocouple or thermal resistor as temperature sensitive element, it can measure temperature of all kinds of liquid, steam and gas medium from -200 to 1600℃, and transform thermocouple's or thermal resistance's signal to 4~20mA standard signal, simultaneously has real-time indication function on the spot.
UTB9 integrated 4-20mA temperature transmitter has LCD or LED display. UTB8 uses integrated electric circuit, which guarantee its stable signal and clear display, this is very convenient to calibrate and inspect the gauges on the scene.
Features
◆Range: -200 ~1600℃;
◆High accuracy, anti-interference, good long-term stability;
◆Integrated structure, can display its real-time measuring value.
