MURPHY 45APE Series Mechanical Pressure Gauges
45APE Dial Pressure Swichgage Instrument

45APE Series | FW Murphy Production Controls | 45APE Series Swichgage | Murphy by Enovation Controls

45APE系列调压仪器是用于压力指示的机械量具。

它包括两个可调式SPDT开关。这些快动开关可用于启动和停止,触发警报和关闭设备。范围从30“ VAC(-100 kPa)[-1 bar]到10,000 psi(138 MPa)[1379 bar]。45APE系列使用带有不锈钢双扇齿轮传动机构的波登管感应单元。当向波登管施加压力时,每个扇区都驱动单独的指针。指示指针(可见指针)显示实际压力读数,包括低和高跳闸点的下方和上方。高低跳变点可在量规前透镜上独立调节。开关操作员的指针(位于表盘后面)已校准为跟随指示指针。高低跳闸点指示器会锁住开关操作员的指针。

MURPHY45APE系列开关仪表是一种用于压力指示的机械式仪表。它包括两个可调SPDT开关。这些速动开关可用于启动和停止、跳闸报警和关闭设备。范围可从30“真空(-100千帕)[-1巴]到10000磅/平方英寸(138兆帕)[1379巴]。MURPHY 45APE Series Swichgage instrument is a mechanical gage for pressure indication. It includes two adjustable SPDT switches. These snap-acting switches can be used for start and stop, to trip alarms and to shut down equipment. Ranges are available from 30” VAC (-100 kPa) [-1 bar] thru 10,000 psi (138 MPa) [1379 bar].

 

Features:

  • Combination indicating gage with independent low and high snap-acting switches
  • Field-adjustable and highly visible low and high pressure trip point indicators
  • Dual-sector geared movement allows for full-scale indication and set point control
  • Panel and surface mount versions available
  • Latching control relay versions available

 

The 45APE Series utilizes a bourdon tube sensing unit with a stainless steel dual-sector geared movement. Each of the sectors drives separate pointers when pressure is applied to the bourdon tube. The indicating pointer (visible pointer) shows actual pressure reading, including below and beyond the low and high trip points. The low and high trip points are adjustable independently on the gage front lens. The switch operator pointer (behind the dial) is calibrated to follow the indicating pointer. The low and high trip point indicators arrest the switch operator pointer. As pressure decreases or increases through the principal of lost motion, the respective snap-switch is tripped.

The 45APE Series models are widely used in applications requiring pressure indication and Form C low and high pressure switches.
