Murphy 20BPG Pressure Murphygages
20BPG / 20BVG / 20BTG (Mechanical Pressure Gauges)
B-Series Murphygage | Murphy by Enovation Controls
Murphy B系列Murphygage仪器是一种高品质的，隔膜驱动指示计。通过Enovation控制内置用相同的重型设计为标准的20系列和25系列Swichgage 仪，B-计更紧凑，仅用于计的应用程序的佳工具。Murphy B系列表可用于石油和天然气，船舶，灌溉，建筑和卡车运输行业的工业发动机和设备，以及监测发动机冷却液，曲轴箱油和变速箱油。
B-Series Murphygage | Murphy by Enovation Controls
每台Murphygage仪器均具有高强度的聚碳酸酯透镜，坚固的钢制表壳和抛光的薄型不锈钢表圈。独特的，统一的隔膜腔室，优质的材料和量具的设计确保了精度和适度超压/过热的防护。
压力墨菲仪
隔膜上的压力变化可转换为精确的机械运动，该机械运动显示在易于读取的模拟刻度盘上。压力端口中的脉动阻尼器有助于消除指针抖动。可以将其卸下进行清洁，以保持压力计的响应和准确性。
真空墨菲仪
0至20或0至30英寸汞柱可用。（0至-68或0至-102 kPa）真空。
温度墨菲仪表
随着温度的升高，传感灯泡中的液体蒸发，从而向隔膜施加压力。机芯将此蒸气压力转换为刻度盘上标定的温度读数。标准毛细管是带有PVC铠装的铜。可选的装甲覆盖层是镀锌钢或316不锈钢（请指定）。可选灯泡类型，紧定螺母和热套管。

MURPHY B系列是一种高品质的隔膜驱动指示计。由Enovation控制器制造，与标准20系列和25系列开关仪表具有相同的重型设计 仪器，B-gage更紧凑，是仅用于测量的佳仪器。它有一个高冲击聚碳酸酯镜头，坚固的钢壳和抛光，低剖面不锈钢边框。独特、统一的隔膜腔、优质材料和表盘运动设计确保了精度和防止中等过压/过温。
MURPHY B-Series Murphygage instrument is a high-quality, diaphragm-actuated indicating gage. Built by Enovation Controls with the same heavy-duty design as the standard 20 series and 25 series Swichgage? instrument, the B-gage is more compact and is the optimum instrument for gage-only applications. It has a high impact polycarbonate lens, sturdy steel case and a polished, low-profile stainless steel bezel. Accuracy and protection from moderate over-pressure/over-temperature are assured by a unique, unitized diaphragm chamber, superior quality materials and the design of the gage movement.
Pressure Murphygage instrument
Pressure changes at the diaphragm convert to accurate mechanical movements that are indicated on an easy-to-read analog dial. A pulsation dampener in the pressure port helps eliminate pointer flutter. It can be removed for cleaning to maintain the gage's response and accuracy.
Vacuum Murphygage instrument
Available in 0 to 20 or 0 to 30 in. Hg. (0 to -68 or 0 to -102 kPa) vacuum.
Temperature Murphygage instrument
As temperature rises, the fluid in the sensing bulb vaporizes to apply pressure on the diaphragm. The movement translates this vapor pressure to a calibrated reading of temperature on the dial. The standard capillary is copper with a PVC armor. Optional armor covering is galvanized steel or 316 stainless steel (specify). Optional bulb types, adaptor nuts and thermowells are available.
The B-Series can be utilized in industrial engines and equipment in the oil field, marine, irrigation, construction and trucking industries as well as monitoring engine coolant, crankcase oil and transmission oil.
Specifications
Dial: White on black; U.S.A. standard scale is dual scale; others available.
