    High quality 4 20ma remote seal hydraulic differential explosion-isolated pressure transmitter

    The monocrystalline silicon pressure/differential pressure transmitter is used to measure the liquid level, density, and pressure of liquids, gases, or vapors, and then convert them into 4-20mAHART current signal outputs. It can also communicate with HART375 or BST Modem through them. Parameter setting, process control. The difference from conventional pressure transmitters is that they use nanocrystalline silicon as the sensor material.


    SLK-D series single crystal silicon intelligent transmitter is a new type of high performance intelligent differential pressure and pressure change which is developed by the company with the introduction of foreign advanced technology and imported foreign monocrystalline silicon sensor. Sender. It adopts the internationally advanced micro-mechanical single crystal silicon sensor technology, and utilizes the excellent stability and repeatability of single crystal silicon material. Through micro-machining process and laser welding and packaging process, the reliability and stability are extremely high. The effect of overloading on static pressure is minimal. HART digital communication technology adds intelligent and digital communication functions to further meet the requirements of high reliability, high stability and intelligence of industrial field measurement team.


    The sensor module uses all-welding technology and has an integrated overload diaphragm, a pressure sensor and a temperature sensor. The temperature sensor serves as a reference for temperature compensation. The positive pressure side of the pressure sensor is connected to the high pressure chamber of the sensor capsule, the negative pressure side of the sensor is connected to the low pressure chamber of the sensor capsule, and the pressure is transmitted to the silicon chip in the sensor through the isolation diaphragm and the filling liquid, so that the pressure sensor is The resistance of the chip changes, resulting in a change in the output voltage of the detection system. The output voltage is proportional to the pressure change and is then converted by the adaptation unit and amplifier into a standardized signal output.


    Piezoresistive pressure sensor SLK-D series is constructed using the piezoresistive effect of single crystal silicon. The monocrystalline silicon wafer is used as an elastic component, and an integrated circuit process is used on the single crystal silicon diaphragm to spread a set of equivalent resistance in a specific direction of the single crystal silicon, and the resistor is connected into a bridge, and the monocrystalline silicon wafer is placed. Inside the sensor cavity. When the pressure changes in the single crystal silicon pressure transmitter, the single crystal silicon is strained, so that the strain resistance directly diffused on it generates a change proportional to the measured pressure, and the corresponding voltage output signal is obtained by the bridge circuit.
