Probe head-mounted temperature transmitter AST3003

RTDthermocoupleHART

AST3003 intelligent digital display temperature transducer is developed by our company is suitable for thermal resistance (RTD), thermocouple, resistance, and voltage signal input, through the HART protocol configuration, sensor signal input and output isolation of high resolution, high precision, low temperature transmitter power consumption. Product module adopts 24 bits ADC acquisition chip, measuring the electrical isolation, guarantee the stability of the transmitter in the interference environment; Cooperate with ultra-low power MCU and built-in cold junction compensation technology, to achieve filtering for signal acquisition, amplification, linearization; Industry pioneered with backlit LCD interface to field measurement is more intuitive, more convenient. Transmitter is applicable to a variety of standard thermal resistance, thermocouple signal input, wide measuring range, high precision; In the industrial field 4 ~ 20 ma output signal directly, is widely used in petrochemical, electric power, metallurgy, medicine, food and other industrial fields. Range of application ◆ The standard thermal resistance, thermocouple sensor (RTD) ◆ Resistance, voltage signal input ◆ Two wire system 4 ~ 20 ma current loop superposition HART ◆ Thermal resistance of two, three, four wire system input mode
