SCC3151 series intelligent transmitterDetailed product description：

Product Introduction

The SCC3151 series intelligent transmitter is a new generation of intelligent transmitter developed and produced by combining the world's advanced, mature and reliable capacitor technology with the actual situation in China through domestic scientific research. In principle, a direct digital capacitor circuit is used to replace the analog signal amplification circuit and A/D conversion circuit, and digital compensation technology is used to compensate for temperature and static pressure, improving measurement accuracy and reducing temperature drift. The transmitter has the characteristics of small size, light weight, easy adjustment, high reliability, and good long-term stability. It is known for its strong one-way overload protection capability and is suitable for harsh environments. It has a high performance price ratio and is currently the mainstream product in the transmitter market.

Technical Features

The use of microprocessors increases flexibility and enhances functionality.
The accuracy is better than 0.1 level, and the range ratio is better than 40:1.
It has both remote and local range and zero adjustment capabilities.
No mechanical transmission components, low maintenance workload, sturdy and vibration resistant.
The membrane material for contact with the medium is optional, and the explosion-proof shell structure is available.
Has strong self diagnostic ability.
The adjustment of zero point and range does not affect each other.
The sensor is equipped with non-volatile memory.
Two line system, compliant with the HART protocol.
The range covers a width of 0-40MPa.
Good stability, high precision, adjustable damping, and strong resistance to unidirectional overload.
All universal components, interchangeable sensors and electronic boards do not affect the characteristics of the transmitter, making maintenance more convenient
