该仪表采用了高精度压力传感器，电路部分以高性能单片机微处理器为核心，具有3位LED数字显示及轻触开关输入的人机界面、具有开关量（报警）输出及4～20mA模拟输出，是在机械继电器无法胜任的条件（如压力剧烈波动、强环境振动、高精度高速度控制、小体积等）下可靠工作的理想选择。
二、性能指标◇测量范围：0～1.6—0～60MPa◇电源电压：16～36VDC◇输出信号：（RL≤250Ω）◇接口螺纹：G1/4◇环境条件：环境温度：-20℃～60℃介质温度：:-20℃～80℃存储温度:-40℃～125℃相对湿度：0～80%耐冲击：≤50g/ms耐振动：≤10g/（0～500HZ）◇输出信号精度：1.0◇过载压力：1.5%倍满量程压力◇最大功耗：≤3W触点容量：24VDC/1.2A（MAX）三、功能根据不同型号，装置可提供下列功能◇三位显示当前压力（正常工作）◇按压力、预设开关点输出开关量◇输出模拟量◇基本设定菜单◇提供四种不同输出模式：◇YSJ341带1路开关量输出（负载最大电流1.2A，无模拟量输出）◇YSJ342带2路开关量输出（负载最大电流1.2A，无模拟量输出）◇YSJ343带1路开关量输出（负载最大电流1.2A）和1路模拟量输出（4～20mA）◇YSJ344带2路开关量输出（负载最大电流1.2A）和1路模拟量输出（4～20mA）四、安装YSJ340可以通过压力管接头（DIN3852内螺纹G1/4），直接装在液压集成快上。
电气连接必须由国家认定合格的电工操作（参考中国电工国家标准规范）。
压力继电器的外壳必须同时良好的接地。
如安装在液压块里，块体通过液压系统接地时有保证的。
若用微型软管安装，客体必须单独接地。
