T121 - Bộ chuyển đổi can nhiệt K, S, R... sang 4-20 mA

Supply SENECA T121 imported programmable thermal resistance, thermoelectric temperature transmitter, signal converter

Description: Isolated two-wire type ( ie, a pair of wires is both a power supply line and a loop powered Universal Converter ). The loop-powered intelligent temperature transmitter (field-mounted temperature transmitter), the input signal of the temperature transmitter. It can be arbitrarily set by hand and computer (specifically for thermal resistance/couple integrated temperature transmitter) . It has the characteristics of small size, light weight and convenient installation. It converts the temperature parameter of the control object into electric signal and transmits it to Display, record, and adjust instruments to perform detection, adjustment, and control of the system. It can be directly installed in the junction box of general industrial thermal resistance and thermocouple, and it has an integrated structure with the field sensing components. This not only saves compensation wires and cables, but also reduces signal transmission distortion and interference, resulting in highly accurate measurements.
