1. Product introduction

　　3151 series is our company developed a new generation pressure/differential pressure transmitter with independent intellectual rights. The sensor adopted foreign advanced technology of high accuracy product. On the conversion principle of using digital compensation technique to compensate temperature, static pressure, so that proved the measurement precision and reduced temperature drifting. This series pressure transmitter had many advantages of long-term stability, high reliability and strong itself diagnosis ability. With its high performance than low cost, so it’s the main product in pressure transmitter industry. The 3151 series smart transmitter is apply for measuring flow, liquid level, remote and pressure (differential pressure, gauge pressure, absolute pressure).

2. characteristics

　　2.1 Adopting the microprocessor to improve the flexibility and functions.

　　2.2 Have the function of self-diagnosis.

　　2.3 Measurement range is so widely that is 0—0.2kPa～42MPa.

　　2.4 Make the precision boost into grade 0.1, range than is 40：1.

　　2.5 The adjustment of zero point and measurement range is not influence each other.

　　2.6 Both with complete set, remote and calibration functions.

　　2.7 2-wire system, conform to HART and ending the communication with HART but not interrupt output.

　　2.8 The sensors Using digital compensation to compensate temperature and pressure.

　　2.9 Good stability performance, high accuracy, damping adjustable, one-way resistance ability.

　　2.10 No mechanical transmission parts, less maintenance workload, strong resistance to vibration.

　　2.11 All interchangeable parts, easy to maintenance.

　　2.12 Adjustment zero and the magnet without opening.

　　2.13 The material of contacting medium diaphragm is optional, safe and explosion-proof, can use in anytime.

　　2.14 The most excellent and reliability.
