product describe:
PT296 is a smart 4-20mA pressure sensor including temperature compensation system, DynalarityTM and a WUYUE advanced PCB. PT296 offers the best specification performance in the circuit. Temperature compensation is based on initial RTD measuring data, compensating temperature change, which result in less drift of about temperature，improving accuracy. After installation, you don’t need zero modulation for temperature change again. PT296 adopts a advanced computing rule to offset linear change, the offsetting is caused by sensor crafts. Complex temperature compensation and Dynalarity decrease up to 80% temperature drift，it also improves 60% accuracy more than other sensor. It uses machining temperature to output ,choosing HART communication standard . explosion-proof, nonflammable and its nature safe equipment, which will be certificated soon. PT296 is fully welded, equipped big diaphragm and optional folio Flange ,easy to install. The design makes the probes can accurately measure temperature and pressure at one point. temperature sensor has 4 kinds of resistances to choose:J,K,E,pt100BO.
