MURPHY 76.PS Pressure Switch
76.PS压力开关
一个紧凑和经济的压力开关，用于延长工作时间的应用。76.PS主要设计用于直接安装发动机，以提供机油压力低故障的电信号。隔离开关触点在工厂设置为关闭低于15 psi（1 bar），但可以在14和24 psi（1.0和1.6 bar）之间进行调整。聚酰亚胺薄膜与空气、机油和其他碳氢介质相容。（不建议接触水基液体。我们在英国的办事处备有一个坚固经济的压力开关，主要用于监测发动机低油压。安装在发动机上的开关具有直接作用触点，出厂设置为关闭低于15 psi（现场可在14和24 psi之间调节）。提供常闭触点或转换触点选项。聚酰亚胺卡普顿隔膜与空气、油或其他碳氢化合物介质相容。
A compact and economical pressure switch for extended duty applications. The 76.PS is primarily designed for direct engine mounting, to provide electrical signalling of a low oil pressure fault.The isolated switch contacts are factory set to close below 15 psi (1 bar), but may be adjusted between 14 and 24 psi (1.0 and 1.6 bar). The polyimide diaphragm is compatible with air, engine oil and other hydrocarbon media. (Contact with waterbased fluids is not recommended.)
Our UK office carries stock of a robust and economical pressure switch, designed primarily for monitoring engine low oil pressure.
The engine-mounted switch features direct action contacts that are factory set to close below 15 psi (field adjustable between 14 and 24 psi). Normally closed or changeover contact options are available. A polyimide Kapton diaphragm gives compatibility with air, oil or other hydrocarbon media.
