Product description:

3151Metal capacitance intelligent transmitter ,3151 Smart differential pressure transmitter ,3151 Metal capacitance type analog transmitter,Based on low voltage reference pressure measurement signals,there are two ports connection with process piping.

Working principle:

When pressure is direct or indirect role in measuring the surface of the diaphragm,When pressure is direct or indirect role in measuring the surface of the diaphragm, make diaphragm produces tiny deformation, the high precision circuit on the measuring diaphragm will into the tiny deformation and stress is proportional to the voltage signal, through the temperature and pressure compensation, and then use special chip to convert the voltage signal to the output of 4-20MA the industry standard.

 Characteristics:

1.Adopting the microprocessor makes the device with increased flexibility, and more power.
2.With higher ability of self diagnosis.
3.No influences between the Zero and span adjustment.
4.With perfect remote and on-site ,adjustment function.
5.Two-wire system,communicate With the HART protocol  without interrupting the output terminal
6.With the digital compensation technology,can compensate to temperature and static pressure.
7.Good stability, high accuracy, damping adjustable, strong resistance to one-way overload
8.Without mechanical transmission parts, less maintenance work,, strong resistance.
9.It is very convenient to maintain as with all common parts.
