This model adopted new technique is suitable for many kinds of liquid medium. The LED control system put the electric signal together with the digital display. Also, it can set the zero calibration, full scale value, dots and damping time. Suitable applications include food, pharmaceutical, petrochemical, metallurgical, water-supplying automatically and so on. 工作原理 抗腐蚀的陶瓷压力传感器没有液体的传递,压力直接作用在陶瓷膜片的正面,使膜片产生微小的形变。厚膜电阻印刷在陶瓷膜片的背面,连接成一个惠斯通电桥(闭桥)。由于压敏电阻的压阻效应,使电桥产生一个与压力、激励电压成正比的的高度线性电压信号。标准的信号根据压力量程的不同标定为 2.0/3.0/3.3mV/V,可以和 应变式传感器相兼容。通过激光标定,传感器具有很高的温度稳定性和时间稳定性,受压后惠斯登电桥桥臂阻值的变化使电桥失去平衡产生了一个与压力成正比的电压输出信号,经过差分归一放大器输出放大后,再经过电压电流的转换,变换成4~20mA 的标准电流信号输出,并可经数显表头直接显示在线压力值。 Working Principle No liquid transport, the pressure effect the face of the ceramic diaphragm to lead a small distortion. Thick film resistance was printed in the back of the diaphragm to form a Wheatstone bridge. And a voltage signal in high-level linearity comes out. The standard signals were signed by 2.0/3.0/3.3mV/V which is compatible with the transmitter. After some inside transform, it comes out as the current of 4~20mA and displayed by the transmitter.

Suggest the supply Us to be 24V. The connected gauge should be RL=250Ω。If you choose other date for Us and RL,the RL can not exceed RL= Vs-12/0.02 . Use wires to seal the holes on the sides of the transmitter or install the signal wire to the holes and fix by tight nut. The hole without used should be sealed.   出厂前压力变送器已按订货要求调试合格,用户无需再做调整。长时间使用后如需重新标定,可分别调整 “调零电位器”和“调量程电位器”。压力量程的下限值对应于4mA,上限值对应20mA. ( Z- 调零电位器 S-调量程电位器) The transmitter has been debugged as the customer’s request, no need to debug again. After long time of using, if needed, it can be debugged by adjust“ Zero electric device” and“ Range electric device”. The down limit of the range should be corresponding with 4mA,and up limit will be with 20mA. ( Z- Zero electric device S- Range electric device) 安装注意事项 1. 直接安装在测量点上(任意角度)。 2. 尽量安装在温度梯度与温度波动小的测压点上,同时避免强振动和冲击。 3. 室外安装时,尽可能放置于保护盒内,避免阳光直射和雨淋,以保持变送器性能稳定和延长使用寿命。 4. 测量蒸汽或其它高温介质时,注意不要使变送器的工作温度超限。必要时请安装散热装置或其它冷却装置连接。 5. 安装时应在变送器和介质之间加装压力截止阀,以便检修和防止取压口堵塞而影响测量。在压力波动范围大的场合还应加装阻尼器或压力缓冲装置。 Installation notes 1. Direct install to the measuring point(any angles). 2. It is better to be with less temperature fluctuation and avoid the strong vibration. 3. If it is needed to install outside of the house, it is better to put it into a protect case to avoid sun and rain. 4. While measuring the high temperature mediums, please do not exceed the temperature limitation. If necessary, fit it with cooling devices. 5. Add pressure cut-off valve between the transmitter and the medium and add the dampers if the pressure changes a lot. 产品详细资料请点击:S.YS4 小巧型数显压力变送器.pdf 变送器、压力变送器、小巧型数显压力变送器YS4
