工作原理working principle
transmitter is composed of sensor and electronic element circuit, pressure of measured medium directly applies on sensor s ceramic diaphragm, force diaphragm to displace tinily in proportion to pressure of medium, under normal working condition, diaphragm displace no more than 0.025mm, electronic circuit detects this displacement, and convert it into standard industrial measuring signal i.e. (4~20ma) corresponding to this pressure.
超压时膜片直接贴到坚固的陶瓷基体上，由于膜片与基体的间隙只有0.1mm，过载时膜片的Zui大位移只能是0.1mm，(此时测量膜片贴到陶瓷支架上，避免损坏)所以从结构上保证了膜片不会产生过大变形。由于膜片采用高性能的工业陶瓷，因而使传感器具有很强的抗冲击及抗过载能力。从衬底电极①和膜片电极②之间可以检测到与压力成比例的电容变化量，电容的变化值经激光微调电路放大输出高达0.5-4.5v 的直流电压，计算机可直接采样。
when overpressure, diaphragm directly stick to solid ceramic base body, as there is only 0.1mm gap between diaphragm and base body, when overpressure, the maximum diaphragm displacement could be no more than 0.1mm, (at that time, measuring diaphragm sticks to ceramic bracket, avoid damage) so structurally prevent diaphragm from excessive deformation. because diaphragm adopts high functional industrial ceramic, sensor is significantly shock-proof and overload-proof. from between lining electrode① and diaphragm electrode②capacitance variant in proportion to pressure can be detected, capacitance variant value is amplified by laser micro adjustment circuit to output direct voltage as high as 0.5-4.5v, computer can sample it directly.

when measuring steam or other high temperature media, make sure transmitter s working temperature limit is observed. fit cooler or other cooling device if necessary.
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精度。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。
when mounting, shut valve should be used between transmitter and medium, for easy maintenance and to prevent pressure taking port from blocking that influences measuring accuracy. damper or pressure buffer should be used where big pressure fluctuation exists.

如何选择压力变送器（具体订货时参考）
how to choose pressure transmitter（refer to when ordering）
(1) 确定测量介质decide measuring medium
根据腐蚀程度的大小选择相应的变送器，一般来说非强酸、强碱均可使用以不锈钢为隔离单元的变送器，否则只能选择专为防腐蚀设计的钛合金等特制变送器。其次还需看测量介质是否粘稠度，干净程度，如果粘稠介质就需要选择硬性隔离单元的变送器。
choose corresponding transmitter according to corrosivity, normally transmitter with stainless steel isolation cell is enough for non strong acid strong alkali, otherwise special chemical seal product made in titanium alloy specially designed for corrosion-proof must be used. secondly, need to know viscosity of measuring medium, cleanliness, in case of very viscous transmitter of rigid isolation cell needs to be used.
(2) 确定测量范围和测量方式
decide measuring range and method
一般选择测量范围时要考虑 实际测量范围，过压测量范围，选择量程以Zui大测量范围为准，同时考虑过压测量范围的大小。 另外需要选择正确的测量方式，如果测量差压必须选择差压变送器。
normally when choosing measuring range, need to consider actual measuring range, overpressure measuring range, choosing range should refer to the biggest measuring range, meanwhile consider volume of overpressure range. in addition, need to choose correct measuring method, if measuring pressure difference, need to use differential pressure transmitter
(3) 确定精度范围，补偿温度范围，使用温度范围
decide accuracy range, compensation temperature range, using temperature range.
根据需要测量的Zui低精度，一般选择略高于所要求Zui低精度的产品。 选择时还需考虑长期稳定性指标。 所谓补偿温度范围即正常工作时测量介质的温度范围，使用温度范围即使用过程中可能出现的Zui大温度范围，一般选择时略大于测量介质的温度范围。
according to minimum accuracy, normally choose a bit higher accuracy meanwhile when choosing, need to consider long term stability compensation temperature range is that measuring medium s temperature range when working normally, using temperature range is the biggest temperature range when using, normally choose a little bigger temperature range than re
(4) 确定供电电源、输出信号、压力螺纹接口、电气接口、机械尺寸等
decide pressure connection, electric connection, mechanical dimensions etc
(5) 确定是否需要防爆，需要防电磁干扰，以及外壳防水的环境指标
decide if need explosion-proof, electro magnetic interference-proof, and ambient factor of water-proof of enclosureys1
