I Introduction
The AST3001 is a Analog-type temperature transmitter with selectable ranges for Pt100 input, and features high precision, low temperature driftand high reliability. The transmitter outputs 4~20mA signal directly in the industrial field, so widely used in the
petrochemical industry, electric power, metallurgy and so on.
II Specifications
Power supply: 7.5~36VDC
Input: Pt100(3-wire)
Zero: -50 to +50ºC
Span(selectable): 100/200/300/400/ 500ºC
Accuracy: 0.2%F.S.
Output: 4~20mA
Sensor break detection: Upscale (27mA), downscale (2.2 mA)
Operating temperature: -20~60ºC
Other measurement range can be customized
III Function Characteristics
Small size, convenient installation
Using surface mounting components, epoxy resin sealing structure, anti-interference and high reliability
Special linear circuit design, high accuracy, good stability and free maintenance
External direct adjustment of zero and full
Sensor break detection
Current signal output, long transmission distance, reduce the error brought by line interference
