2022-05-07
●Description:
■STD400 is an electronic average transmitter that converts the average from temperature measurements into one electric current signal 4 – 20 mA.
■The transmitter is used for temperature measurement in air ducts.
■Two versions available:
▲The transmitter with an immersion length of 0,4 m. The measurement is done at 5 points equally spread over the length.
▲A copper tube protects the 5 measuring points. The tube can be bent max R = 50 mm to accomodate the shape of the duct.
▲For larger ducts use the transmitters with immersion length of 3 m or 6 m. The measurement is done over the entire sensor length.
■The transmitter is delivered as a complete unit, comprising a junction box with amplifier and sensors.
■The transmitter shall be connected with a 2-wire cable, which serves both as power supply and for signal transmission.
■The reading of the measured signal is done over an external load resistance.
