I. overview

BP801The diffused silicon piezoresistive pressure transmitter is a high performance pressure transmitter designed for the use of harsh environments. The shape is a sophisticated integration of stainless steel structure, has the advantages of convenient installation, vibration resistance and good impact resistance, high precision and good stability, is widely used in petroleum, chemical, metallurgy, water, electricity, food, pharmaceutical and other industries, the pressure level measurement and process control.

Two. Working principle

Based on the piezoresistive effect of silicon, monocrystalline silicon as substrate, according to specific crystal, using micromachining technology to form elastic element is advanced, with integrated circuit technology in its proper position to form four equivalent strain resistance, composed of Wheatstone bridge, applying a constant voltage to the bridge (flow), when the pressure (differential pressure) the effect of elastic element, so that the output corresponding to the pressure applied to a voltage signal proportional to the voltage through the electronic circuit, signal amplification into three wire0-5VOutput.Three.

When installing, check whether the field interface is consistent with the product interface according to the product connection mode and thread type. If the thread interface, should be slowly tightened, pay attention to sealing, torque can not be directly added to the transmitter shell, can only be added to the six sides of the pressure interface.
