Product Overview
T3051DP monocrystalline silicon remote differential pressure transmitter is used to prevent the medium in the pipeline directly into the transmitter pressure sensor components, remote transmission device and transmitter is connected by the capillary tube filled with fluid.T3051DP monocrystalline silicon remote differential pressure transmitter is used for gas, liquid or steam differential pressure or level measurement, and will be measured by the signal through the digital amplifier converted into a 4-20Ma standard current signal output. T3051DP can be adjusted by its own keypad or through the hand manipulator.

Third, the working principle of monocrystalline silicon pressure sensor
Monocrystalline silicon pressure transmitter using monocrystalline silicon piezoresistive effect, the use of monocrystalline silicon chip for the elastic element, in the monocrystalline silicon diaphragm using the process of integrated circuits; in the specific direction of the monocrystalline silicon diffusion of a group of equivalent resistance, and the resistance connected to the bridge circuit, the monocrystalline silicon chip is placed in the sensor cavity. When the pressure changes, the monocrystalline silicon produces; strain, so that the direct diffusion of the strain resistance on the top of the strain resistance produced by the measured pressure into a proportional change, and then by the bridge circuit to obtain the corresponding voltage output signal.
