NAGANO KEIKI DG26 Differential Pressure Gauge |

Made in Japan
Manufacturer: NAGANO KEIKI
Model: DG26 Differential Pressure Gauge

These differential pressure gauges are compactly designed to measure the pressure difference (differential pressure) of two points.
They can also be used to measure tank liquid level, loss of head of strainers, or combined with an office to measure the flow of a pipeline.
These differential pressure gauges with electric contacts use a microswitch for ON-OFF control.

Features

Enclosed liquid helps withstanding high pressure preventing damage caused by valve operation or　reversed process pressure (within proof pressure)

Selectable upper connection mounting or lower connection mounting

Difference Pressure Range

0 to 5, 8, 10kPa (DG26)/
0 to 20, 25, 50, 70kPa (DG16・17)
0 to 0.1, 0.2, 0.3MPa (DG16・17)

Application

Differential pressure, tank level measurement, strainer pressure loss measurement
Filter clogging in pipeline system, flow measurement
