Zhejiang, Jiangsu and Shanghai factory direct custom processing intelligent differential pressure transmitter

Intelligent differential pressure transmitter 1? Overview diffused silicon pressure transmitter has a reliable, stable performance, easy installation, small size, light weight, high cost performance points, to get wide variety of positive and negative pressure measurements Applications. Imported diffused silicon or core as a pressure sensing element, the sensor signal is converted into a high-performance electronic amplifier 0-10mA or 4-20mA output signal unity. It can replace the traditional remote pressure gauge, a Hall element, a differential transmitter and has DDZ-Ⅱ and DDZ-Ⅲ type of transmitter performance. It can be used with various types of moving coil indicator, digital pressure gauge, supporting the use of electronic potentiometer, also with smart regulation or computer systems supporting the use. Diffused silicon diffused silicon pressure transmitter selection of imported chips made changes when the external level, pressure is applied to a stainless steel diaphragm, silicone oil passes through the isolation diffusion silicon pressure sensitive bridge output voltage changes caused by the elements, through sophisticated compensation technique, signal processing techniques, into a standard current signal. It changes the current signal is proportional to the level change. 2? Features? Using widely tested media, can be measured oil, water and compatible with 316 stainless steel and 304 stainless steel was burnt, with some corrosion resistance. ? High accuracy, high stability, use of imported original sensor, good linearity, high temperature stability. ? Small size, light weight, installation, commissioning, easy to use? Stainless steel fully enclosed shell, waterproof good. ? Pressure sensor directly measured liquid level sensing pressure from the media bubble, and accumulation. 3? Work When the pressure signal is applied to the sensor, a pressure sensor converts the pressure signal into an electrical signal by the differential amplifier and the output amplifier, and finally by the V / A voltage current into the measured medium (liquid) level pressure into 4-20mA standard current output signal linear correspondence relationship.
